114-567: Bralorne ( / ˈ b r eɪ l ɔːr n / BRAY -lorn ) is a historic Canadian gold mining community in the Bridge River District of British Columbia , some 130 km on dirt roads west of the town of Lillooet . Gold has been the central element in the area's history going back to the 1858-1860 Fraser River Gold Rush . Miners rushed to the Cayoosh and Bridge River areas looking for placer deposits, One named Cadwallader looked for

228-698: A combination of factors including the depletion of easily accessible gold deposits, harsh weather conditions, and the political instability at the time. The Welsh gold rush occurred in Wales , more so in the Dolgellau area of Gwynedd , during the 19th century. Gold deposits were discovered in Welsh mountains, with reports of gold being found in rivers Mawddach and Tryweryn . By the mid-19th century, commercial mining operations had begun. Wales' gold gained popularity for its quality and rarity, leading to its use in royal jewelry for

342-459: A common "Saharan-Sudanese culture", and drew their reinforcements from the same great source, even though, as time went by, they also absorbed a number of wanderers from the Near East". Biological anthropologists Shomarka Keita and A.J. Boyce have stated that the "Studies of crania from southern predynastic Egypt , from the formative period (4000-3100 B.C.), show them usually to be more similar to

456-716: A critical source of income and livelihood, providing employment opportunities and economic support in regions with limited alternative options. Artisanal mining operations vary in scale, from individuals panning for gold in rivers and streams, to small groups working collectibely in informal mining camps, often referred to as ' galamsey ' in West Africa . Gold mining can create employment opportunities in mining operations and related sectors. Howevers, these jobs may be temporary. The sector's reliance on fluctuating global gold prices can lead to economic stability for communities dependent on mining. The discovery of significant gold deposits in

570-437: A gravel screening plant and sluice box floating in a temporary pond. The pond is excavated in the gravel bar and filled from the natural water table. "Pay" gravel is excavated from the front face of the pond and processed through the floating plant, with the gold trapped in the onboard sluice box and tailings stacked behind the plant, steadily filling in the back of the pond as the operation moves forward. This type of gold mining

684-569: A large circular dwelling, and a palace-like structure. Classic Kerma rulers employed "a good many Egyptians", according to the Egyptian Execration texts. Kerma culture was militaristic, as attested by many archers' burials and bronze daggers/swords found in their graves. Other signs of Nubia's military prowess are the frequent use of Nubians in Egypt's military and Egypt's need to construct numerous fortresses to defend their southern border from

798-467: A large scale to extract gold from extensive alluvial (loose sediment) deposits, such as those at Las Medulas . Mining was under the control of the state but the mines may have been leased to civilian contractors some time later. The gold served as the primary medium of exchange within the empire, and was an important motive in the Roman conquest of Britain by Claudius in the first century AD; although there

912-574: A lasting legacy that was merged with indigenous C-group customs. Egyptians remaining at the garrison towns started to merge with the C-group Nubians in Lower Nubia. The C-group quickly adopted Egyptian customs and culture, as attested by their graves, and lived together with the remaining Egyptians in garrison towns. After Upper Nubia annexed Lower Nubia around 1700 BC, the Kingdom of Kush began to control

1026-488: A lower grade. Tailings can contain lead, mercury, cadmium, and arsenic. These toxins can pose health risks for local communities. Arsenic is typically found in gold-containing ores, and gold processing may contaminate groundwater or the atmosphere. This pollution may persist for decades. Furthermore, mining operations use large quantities of water for processing ore and can result in the contamination of water sources with heavy metals, such as mercury and cyanide , used in

1140-669: A military occupation of Thebes to the High Priest, which later led to the Civil war in Thebes. By 1082 BC, Ramesses XI finally sent help to the High Priest. Panehesy continued his revolt and the city of Thebes suffered from "war, famine, and plunderings". Panehesy initially succeeded and the High Priest fled Thebes. Panehesy pursued the High Priest as far as Middle Egypt before Egyptian forces pushed Panehesy and his troops out of Egypt and into Lower Nubia. Ramesses sent new leadership to Thebes: Herihor

1254-755: A monumental scale." At Karnak, the Sacred Lake structures, the kiosk in the first court, and the colonnades at the temple entrance are all built by Taharqa and Mentuemhet. In addition to architecture, the Kingdom of Kush was deeply influenced by Egyptian culture. By 780 BC, Amun was the main god of Kush and "intense contacts with Thebes" were maintained. Kush used the methods of Egyptian art and writing. The Nubian elite adopted many Egyptian customs and gave their children Egyptian names. Although some Nubian customs and beliefs (e.g. burial practices) continued to be practiced, Egyptianization dominated in ideas, practices, and iconography. The cultural Egyptianization of Nubia

1368-447: A region often sees a flood of resources and development, which lasts as long as the mines are economic. When goldfields begin to decline in production, local economies find themselves destabilised and overly reliant upon an industry that will inevitably abandon the region when gold deposits are sufficiently depleted; leaving the areas without proper rehabilitation. Nubia From the 3rd century BC to 3rd century AD, northern Nubia

1482-467: A series of towns below the Second Cataract with heavy fortresses that had enclosures and drawbridges. Sesotris III relentlessly expanded his kingdom into Nubia (from 1866 to 1863 BC) and erected massive river forts including Buhen , Semna , Shalfak and Toshka at Uronarti to gain more control over the trade routes in Lower Nubia. They also provided direct access to trade with Upper Nubia, which

1596-727: A tributary of the Klondike River by George Carmack and his Indigenous companions, Skookum Jim Mason and Tagish Charlie . As prospectors arrived in Klondike, makeshift towns and settlements sprang up along the rivers, including Dawson City , which because the largest town in Yukon at the height of the gold rush. Prospectors employed various mining techniques to extract gold from the Klondike's streams and riverbeds, including placer mining, dredging, and hydraulic mining. The Carlin Trend of Nevada, U.S.,

1710-418: Is a cyanide extraction method, or gold cyanidation, introduced in the late 1800s. This a metallurgical technique used to extract gold from lower grade ores by converting gold into a water-soluble coordination complex. Finely ground rock is treated with a solution of sodium cyanide . The extract is absorbed onto carbon and then removed from the carbon with a solution of caustic soda and cyanide. Gold cyanide

1824-429: Is a method of extracting gold from alluvial deposits such as sand, gravel, and sediment. These are known as placer deposits which are typically found in riverbeds, stream beds, and floodplains. These deposits typically contain minerals that are resistant to weathering and eroision like gold , platinum , diamonds , and more. They are characterized by their relatively high concentration of valuable minerals compared to

1938-562: Is called Nubiology . Historically, the people of Nubia spoke at least two varieties of Nubian languages , a subfamily that includes Nobiin (the descendant of Old Nubian), Dongolawi , Midob and several related varieties in the northern part of the Nuba Mountains in South Kordofan . The Birgid language was spoken north of Nyala in Darfur , but became extinct as late as 1970. However,

2052-415: Is characterized by its low cost, as each rock is moved only once. It also has low environmental impact, as no stripping of vegetation or overburden is necessary, and all process water is fully recycled. Such operations are typical on New Zealand's South Island and in the Klondike region of Canada. Also called a cradle, a rocker box uses riffles located in a high-walled box to trap gold in a similar manner to

2166-616: Is done by small-scale miners using suction dredges. These are small machines that float on the water and are usually operated by one or two people. A suction dredge consists of a sluice box supported by pontoons, attached to a suction hose which is controlled by a miner working beneath the water. This method is particularly popular in areas where gold is found at river bottoms or submerge deposits . Suction dredging can have environmental impacts, moreso on aquatic habitats and water quality. Regulations and best practices are often in place to minimize these impacts. State dredging permits in many of

2280-436: Is essentially a man made channel with riffles set in the bottom. The riffles are designed to create dead zones in the current to allow gold to drop out of suspension. The box is placed in the stream to channel water flow. Gold-bearing material is placed at the top of the box. The material is carried by the current through the volt where gold and other dense material settles out behind the riffles. Less dense material flows out of

2394-841: Is estimated that the total gold production in Karnataka to date is 1000 tons. The mining of the Hungarian deposit (present-day Slovakia) primarily around Kremnica was the largest of the Medieval period in Europe. In South America, gold mining in the Andes dates back to thousands of years, with the Inca empire employing extensive gold mining operations in regions such as present-day Peru and Ecuador . They used stone tools and simple mining techniques to extract gold from rivers, streams, and surface deposits. During

However, there is no known depiction of her painted during her lifetime (she is represented with the same light skin as other represented individuals in tomb TT15, before her deification); the earliest black skin depiction appears in tomb TT161, c. 150 years after her death. Egyptologist Barbara Lesko wrote in 1996 that Ahmose-Nefertari

2622-677: Is only one known Roman gold mine at Dolaucothi in west Wales. Gold was a prime motivation for the campaign in Dacia when the Romans invaded Transylvania in what is now modern Romania in the second century AD. The legions were led by the emperor Trajan, and their exploits are shown on Trajan's Column in Rome and the several reproductions of the column elsewhere (such as the Victoria and Albert Museum in London ). Under

2736-962: Is produced by major corporations, there are an estimated 10 to 15 million small-scale artisanal gold miners worldwide. Around 4.5 million of them are women, and an estimated 600,000 children work in illegal artisanal gold mines. Artisanal miners use rudimentary methods to extract and process gold. Many of these people are mining to escape extreme poverty , unemployment and landlessness . In Ghana, galamsey miners are estimated to number 20,000 to 50,000. In neighboring francophone countries, such workers are called orpailleurs . In Brazil, Venezuela, Suriname, and French Guiana, workers are called garimpeiros . These workers are not required to claim responsibility for their social and environmental impacts. Miners risk government persecution, mine shaft collapses, and toxic poisoning from unsafe chemicals used in processing, such as mercury. For example, in Ghana during 2009,

2850-628: Is then converted to relatively pure gold through gold parting . There are many environmental hazards associated with this extraction method, largely due to the high toxicity of the cyanide compounds. Furthermore, there are potentials for accidental spills or leaks to cause harm to aquatic ecosystems and human health. For example, in 2000, the Baia Mare cyanide spill in northern Romania released approximately 100,000 cubic metres (3,500,000 cu ft) of waste water contaminated with heavy metal sludge and up to 120 long tons (122 t) of cyanide into

2964-519: Is unknown, but some of the oldest known gold artifacts were found in the Varna Necropolis in Bulgaria . The graves of the necropolis were built between 4700 and 4200 BC, indicating that gold mining could be at least 6,724 years old. During a series of excavations carried out between 1878 and 1992, several graves were found with more than 6kg of gold. A group of German and Georgian archaeologists claims

3078-615: The British royal family . During the 19th century, numerous gold rushes in remote regions around the globe caused large migrations of miners, such as the California Gold Rush of 1849. This is one of the most famous gold rushes in history. The discovery of gold at Sutter's Mill in California sparked a massive migration of people from around the world to California in search of gold. The rush significantly accelerated westward expansion in

3192-690: The Bronze Age , sites in the Eastern Desert became a great source of gold-mining for nomadic Nubians, who used "two-hand-mallets" and "grinding ore extraction ." By the Old Kingdom , the oval mallet was introduced for mining. By the Middle Kingdom , stone mortars to process ores and a new gold-washing technique were introduced. During the New Kingdom , Nubian mining expanded under Egyptian occupation with

3306-552: The C-Group culture and the Blemmyes ) spoke Cushitic languages before the spread of Eastern Sudanic languages from southern or Upper Nubia . Nubia was divided into three major regions: Upper, Middle, and Lower Nubia, in reference to their locations along the Nile . "Lower" referred to regions downstream (further north) and "upper" to regions upstream (further south). Lower Nubia lay between

3420-568: The Dompoase mine collapse killed 18 workers. It was the worst mining disaster in Ghanaian history. Children in these mines suffer extremely harsh working conditions and various hazards such as collapsing tunnels, explosions, and chemical exposure. Children may be especially vulnerable to these hazards and many suffer from serious respiratory conditions, hearing, and vision problems. Gold mining by large multi-national corporations produces about 80% of

3534-664: The First Dynasty of Egypt buried at Abydos were of Nubian origin. However, several biological anthropological studies have shown the Badarian and Naqada people to be closely related to the Nubian and other, tropical African populations. Also, the proto-dynastic kings emerged from the Naqada region. A uniform culture of nomadic herders, called the Gash group , existed from 3000 to 1500 BC to

The Pan Grave and C-Group definitely interacted: Pan Grave pottery is characterized by more limited incised lines than the C-Group's and generally have interspersed undecorated spaces within the geometric schemes. In 2300 BC, Nubia was first mentioned in Old Kingdom Egyptian accounts of trade missions. The Egyptians referred to Lower Nubia as Wawat, Irtjet, and Setju, while they referred to Upper Nubia as Yam. Some authors believe that Irtjet and Setju could also have been in Upper Nubia. They referred to Nubians dwelling near

3876-457: The Sakdrisi site in southern Georgia , dating to the 3rd or 4th millennium BC, may be the world's oldest known gold mine. Gold has been prized by humans since prehistoric times. Archaeological evidence suggests that humans were mining gold as far back as 4000 BCE, with some the earliest known gold artifacts dating back to ancient Mesopotamia . Particularly in the region of present-day Iraq, gold

3990-511: The Tisza River. Historically, mercury was used extensively in placer gold mining in order to form mercury-gold amalgam with smaller gold particles, and thereby increase the gold recovery rates. First, the gold ore is crushed and ground to a fine powder to expose the gold particles for amalgamation. Then, this finely ground ore is mixed with liquid mercury to amalgamate it. Mercury forms an amalgam, an alloy, with gold particles to allow for

4104-677: The Twelfth Dynasty had strong Nubian features, due to the origin of the dynasty in the Aswan region of southern Egypt. He also identified the pharaoh Sequenre Tao of the Seventeenth Dynasty , as having Nubian features. Many scholars in recent years have argued that the mother of Amenemhat I, founder of the Twelfth Dynasty was of Nubian origin. After a period of withdrawal, the Middle Kingdom of Egypt conquered Lower Nubia from 2000 to 1700 BC. By 1900 BC, King Sesostris I began building

4218-463: The 15th Dynasty, isolated Nubian communities in Egypt, and some bowmen communities. C-Group pottery is characterized by all-over incised geometric lines with white infill and impressed imitations of basketry. Lower Nubia was controlled by Egypt from 2000 to 1700 BC and Upper Nubia from 1700 to 1525 BC. From 2200 to 1700 BC, the Pan Grave culture appeared in Lower Nubia. Some of the people were likely

Historically, mining gold from alluvial deposits used manual separation processes, such as gold panning . The expansion of gold mining to ores that are not on the surface has led to more complex extraction processes such as pit mining and gold cyanidation . In

4674-521: The 20th and 21st centuries, most volume of mining was done by large corporations. However, the value of gold has led to millions of small, artisanal miners in many parts of the Global South . Like all mining, human rights and environmental issues are common in the gold mining industry, and can result in environmental conflict . In mines with less regulation, health and safety risks are much higher. The exact date that humans first began to mine gold

As a consequence of this, some have left the rainforest to move to cities which further puts them at risk to disease, homelessness, and poverty. Artisanal gold mining is widespread across Africa , occurring in numerous countries including Ghana , Mali , Burkina Faso , Tanzania , Zimbabwe , and many others. For many individuals and communities in rural Africa, artisanal gold mining represents

5016-509: The C-group in Upper Nubia vanish by 2000 BC and Kerma culture began to dominate Upper Nubia. The power of an independent Upper Nubia increased around 1700 BC and Upper Nubia dominated Lower Nubia. An Egyptian official, Harkhuf, mentions that Irtjet, Setjet, and Wawat all combined under a single ruler. By 1650 BC, Egyptian texts started to refer to only two kingdoms in Nubia: Kush and Shaat. Kush

5130-572: The Early A-Group culture , arose in Lower Nubia. They were sedentary agriculturalists, traded with the Egyptians and exported gold. This trade is supported archaeologically by large amounts of Egyptian commodities deposited in the A-Group graves. The imports consisted of gold objects, copper tools, faience amulets and beads, seals, slate palettes, stone vessels, and a variety of pots. During this time,

5244-875: The Eastern Roman Empire Emperor Justinian's rule, gold was mined in the Balkans, Anatolia, Armenia, Egypt, and Nubia. In the area of the Kolar Gold Fields in Bangarpet Taluk , Kolar district of Karnataka state, India; gold was first mined prior to the 2nd and 3rd century AD by digging small pits. Golden objects found in Harappa and Mohenjo-daro have been traced to Kolar through the analysis of impurities – the impurities include 11% silver concentration, found only in KGF ore. The Champion reef at

5358-689: The Egyptian Nile Valley during these periods, which may be due to problems in site preservation. Several scholars have argued that the African origins of the Egyptian civilization derived from pastoral communities which emerged in both the Egyptian and Sudanese regions of the Nile Valley in the fifth millennium BCE. Dietrich Wildung (2018) examined Eastern Saharan pottery styles and Sudanese stone sculptures and suggested these artefacts were transmitted across

5472-627: The Egyptian military as scouts and minor workers before being incorporated into the Egyptian army. In the army, the Medjay served as garrison troops in Egyptian fortifications in Nubia and patrolled the deserts as a kind of gendarmerie , or elite paramilitary police force, to prevent their fellow Medjay tribespeople from further attacking Egyptian assets in the region. The Medjay were often used to protect valuable areas, especially royal and religious complexes. Although they are most notable for their protection of

5586-430: The Egyptian occupation of Nubia, there were temple towns with Egyptian cults, but "production and redistribution" was based mostly on indigenous social structures. The El Kurru chiefdom likely played a major role in the development of the Kingdom of Kush due to its access to gold producing areas, control of caravan routes, more arable land, and participation in international trade. "There can be no doubt that el-Kurru

5700-827: The First and the Second Cataracts within the current borders of Egypt, Middle Nubia lay between the Second and the Third Cataracts, and Upper Nubia lay south of the Third Cataract. Archaeological evidence attests to long histories of fishing-hunting-gathering, and later herding, throughout the Nile Valley. Affad 23 is an archaeological site located in the Affad region of southern Dongola Reach in northern Sudan , which hosts "the well-preserved remains of prehistoric camps (relics of

5814-412: The Highlands during the 16th and 17th century. Gold deposits were discovered in rivers and streams, leading to a surge in prospecting and mining activity. The Scottish Crown took an interest in gold discoveries, in hopes of aiding the kingdom's economy and revenue. King James IV of Scotland established a royal mint to produce gold coins from Scottish gold. The Scottish gold rush eventually waned due to

5928-477: The Kushite conquest of Egyptian territories. The Napatan Empire ushered in the age of Egyptian archaism, or a return to a historical past, which was embodied by a concentrated effort at religious renewal and restoration of Egypt's holy places. Piye expanded the Temple of Amun at Jebel Barkal by adding "an immense colonnaded forecourt". Shabaka restored the great Egyptian monuments and temples, "unlike his Libyan predecessors". Taharqa enriched Thebes on

6042-722: The Middle Ages, Europe experience several gold rushes. Most notably in regions like Transylvania, Scotland, and Wales. These rushes were often small-scale and localised compared to later rushes in history. The Transylvania gold rush took place in the Kingdom of Hungary (present-day Romania ), primarily in the region of Transylvania during the medieval period. Transylvania was known for its rich mineral resources including gold, silver, and other metals. Miners in Transylvania used both surface and underground mining techniques to extract gold from alluvial deposits and veins. These methods include panning, sluicing, and rudimentary shaft mining. The Scottish gold rush occurred in Scotland, primarily in

6156-467: The Middle East. The primitive working conditions for the slaves are recorded by Diodorus Siculus . One of the oldest maps known is of a gold mine in Nubia: the Turin Papyrus Map dating to about 1160 BC; it is also one of the earliest characterized road maps in existence. Nubians were an integral part of New Kingdom Egyptian society. Some scholars state that Nubians were included in the 18th Dynasty of Egypt 's royal family. Ahmose-Nefertari , "arguably

6270-403: The Naqada people and the Nubian A-Group people were from different cultures. Kathryn Bard states that "Naqada cultural burials contain very few Nubian craft goods, which suggests that while Egyptian goods were exported to Nubia and were buried in A-Group graves, A-Group goods were of little interest further north." According to anthropologist Jane Hill, there is no evidence that the pharaohs of

6384-417: The New Kingdom pharaohs brought all of Nubia under Egyptian rule from 1500 to 1070 BC. After 1070 BC, there were continued hostilities with Egypt, which led Nubians to concentrate in Upper Nubia. Within 200 years, a fully formed Kushite state, based at Napata, began to exert its influence on Upper (Southern) Egypt. When the Middle Kingdom Egyptians pulled out of the Napata region around 1700 BC, they left

The poorly known " pre-Kerma " culture existed in Upper (Southern) Nubia on a stretch of fertile farmland just south of the Third Cataract . Nubia has one of the oldest civilizations in the world. This history is often intertwined with Egypt to the north. Around 3500 BC, the second "Nubian" culture, termed

6612-685: The Nubians began creating distinctive black topped, red pottery. The A-Group population have been described as ethnically “very similar” to the pre-dynastic Egyptians in physical characteristics. Around 3100 BC, the A-group transitioned from the Early to Classical phases. "Arguably royal burials are known only at Qustul and possibly Sayala." During this period, the wealth of A-group kings rivaled Egyptian kings. Royal A-group graves contained gold and richly decorated pottery. Some scholars believe Nubian A-Group rulers and early Egyptian pharaohs used related royal symbols; similarities in A-Group Nubia and Upper Egypt rock art support this position. Scholars from

6726-439: The Nubians. Despite assimilation, the Nubian elite remained rebellious during Egyptian occupation. There were numerous rebellions and "military conflict occurred almost under every reign until the 20th dynasty". At one point, Kerma came very close to conquering Egypt: Egypt suffered a serious defeat at the hands of the Kingdom of Kush . According to Davies, head of the joint British Museum and Egyptian archaeological team,

6840-407: The Qustul rulers adopted or emulated the symbols of Egyptian pharaohs. According to David Wengrow , the A-Group polity of the late 4th millenninum BCE is poorly understood since most of the archaeological remains are submerged underneath Lake Nasser. Frank Yurco also remarked that depictions of pharonic iconography such as the royal crowns, Horus falcons and victory scenes were concentrated in

He further elaborated that "Egyptian writing arose in Naqadan Upper Egypt and A-Group Nubia, and not in the Delta cultures, where the direct Western Asian contact was made, further vitiates the Mesopotamian-influence argument". The archaeological cemeteries at Qustul are no longer available for excavations since the flooding of Lake Nasser . The earliest representations of pharaonic iconography have been excavated from Nag el-Hamdulab in Aswan ,

Egypt conquered Lower and Upper Nubia from 1500 to 1070 BC. However, the Kingdom of Kush survived longer than Egypt. After the Theban 17th Dynasty New Kingdom of Egypt (c. 1532–1070 BC) expelled the Canaanite Hyksos from Egypt, they turned their imperial ambitions to Nubia. By

During Egypt's Second Intermediate period, the Kushites reached the height of their Bronze Age power and completely controlled southern trade with Egypt. They maintained diplomatic ties with the Thebans and Hyksos until

7638-580: The box as tailings . Larger commercial placer mining operations employ screening plants, or trommels , to remove the larger alluvial materials such as boulders and gravel, before concentrating the remainder in a sluice box or jig plant. After the gold is sorted through trommels, it is then placed through regular sluice boxes for further sorting. These operations typically include diesel powered, earth moving equipment including excavators, bulldozers, wheel loaders , and rock trucks. Although this method has largely been replaced by modern methods, some dredging

At this time, kings at Qustul likely ruled all of Lower Nubia and demonstrated the political centralization of Nubian society. The A-Group culture came to an end sometime between 3100 and 2900 BC, when it was apparently destroyed by the First Dynasty rulers of Egypt. There are no records of settlement in Lower Nubia for

8094-432: The efficient capture of gold from the ore. The gold is concentrated by boiling away the mercury from the amalgam . This process is called retorting. This is effective in extracting very small gold particles, but the process is hazardous due to the toxicity of mercury vapour. Large-scale use of mercury stopped in the 1960s. However, mercury is still used in artisanal and small-scale gold mining (ASGM). While most gold

8208-458: The end of Thutmose I 's reign (1520 BC), all of Lower Nubia had been annexed. After a long campaign, Egypt also conquered the Kingdom of Kerma in Upper Nubia and held both areas until 1070 BC. The Egyptian empire expanded into the Fourth Cataract, and a new administrative center was built at Napata , which became a gold and incense production area. Egypt became a prime source of gold in

8322-762: The extraction process. This pollution can have detrimental effects on aquatic ecosystems and human health. Soil degradation has also been found to be impacted by gold mining. Mining activities can disturb soil structure, leading to erosion, sedimentation of waterways, and loss of fertile land for agriculture or vegetation regrowth. More evidently, dust and emissions from mining machiner and processing facilities can contribute to air pollution, impacting air quality and potentially causings respiratory problems for nearby communities. Large-scale gold mining projects may require land acquisition and resettlement of local communities, leading to displacement, loss of livelihoods, and disruption of traditional ways of life. In addition to

8436-619: The extreme southern region of Egypt which borders the Sudan, with an estimated dating range between 3200 and 3100 BC. Writing developed in Egypt around 3300 BC. In their writings, Egyptians referred to Nubia as " Ta-Seti ", or "The Land of the Bow," as the Nubians were known to be expert archers. More recent and broader studies have determined that the distinct pottery styles, differing burial practices, different grave goods, and site distribution all indicate that

8550-589: The first Nubian kingdom to unify much of the region arose. The Classic Kerma culture, named for its royal capital at Kerma , was one of the earliest urban centers in the Nile region and oldest city in Africa outside of Egypt. The Kerma group spoke either languages of the Cushitic branch or, according to more recent research, Nilo-Saharan languages of the Eastern Sudanic branch. By 1650 BC (Classic Kerma phase),

8664-694: The gold supply. Most gold is mined in developing nations. Large mining companies play a key role in globalisation of the economy by linking rich and poor companies. Newmont and Barrick Gold are the largest gold mining companies in the world, but there are many smaller corporations in the industry. Local communities are frequently vulnerable to environmental degradation caused by large mining companies and may lack government protection or industry regulation. For example, thousands of people around Lega Dembi mine are exposed to mercury, arsenic, and other toxins resulting in widespread health problems and birth defects. Vulnerable communities may also lose their land to

8778-605: The great East African substratum". Williams also wrote that Qustul "could well have been the seat of Egypt's founding dynasty". David O'Connor wrote that the Qustul incense burner provides evidence that the A-group Nubian culture in Qustul marked the "pivotal change" from predynastic to dynastic "Egyptian monumental art". However, "most scholars do not agree with this hypothesis", as more recent finds in Egypt indicate that this iconography originated in Egypt instead of Nubia, and that

8892-553: The growth of cities like Melbourne and Sydney . The discovery of gold in the Witwatersrand led to the Second Boer War and ultimately the founding of South Africa. This transformed the region into one of the wealthiest gold-producing areas in the world. This rush played a crucial role in the development of South Africa's economy and lead to the establishment of Johannesburg, known as the 'city of gold'. Gold-bearing reefs in

9006-750: The heat is unbearable for humans, and air conditioning is required for the safety of the workers. The first such mine to receive air conditioning was Robinson Deep , at that time the deepest mine in the world for any mineral. Gold is also produced by mining in which it is not the principal product. Large copper mines, such as the Bingham Canyon mine in Utah, often recover considerable amounts of gold and other metals along with copper. Sand and gravel pits, like those in Denver (Colorado), may recover small amounts of gold in their wash operations. The largest producing gold mine in

9120-584: The invention of the grinding mill . Additionally, gold was associated with the sun god Ra and was believed to be eternal and indestructible, symbolising the pharoah's divine power and afterlife. Gold has also been found in the tombs of Tutankhamun and other pharoahs. During the Bronze Age, gold objects were also plentiful; especially in Ireland and Spain. Romans employed slave labour and used hydraulic mining methods, such as hushing and ground sluicing on

9234-497: The kings of Kerma were powerful enough to organize the labor for monumental town walls and large mud brick structures, such as the Eastern and Western Deffufas (50 by 25 by 18 meters). They also had rich tombs with possessions for the afterlife and large human sacrifices . George Andrew Reisner excavated sites at the royal city of Kerma and found distinctive Nubian architecture , such as large pebble covered tombs (90 meters in diameter),

9348-539: The linguistic identity of the ancient Kerma culture of southern and central Nubia (also known as Upper Nubia ), is uncertain; some research suggests that it belonged to the Cushitic branch of the Afroasiatic languages , while more recent studies indicate that the Kerma culture belonged to the Eastern Sudanic branch of Nilo-Saharan languages instead, and that other peoples of northern or Lower Nubia north of Kerma (such as

9462-461: The lowest ever recorded for tropical forests, with there being little to no tree regeneration at abandoned mining camps, even after several years. The Amazon rainforest is at risk for 'savannization', which is the gradual transformation of a tropical rainforest into a savannah. This would ultimately lead to a collapse of biodiversity, ecosystems, and climate. Gold mining produces more waste than mining of other minerals, because it can be mined at

9576-663: The mine. Some large companies have attempted to build local legitimacy through corporate responsibility initiatives and local development. Gold mining can significantly alter the natural environment. Gold mining activities in tropical forests are increasingly causing deforestation along rivers and in remote areas rich in biodiversity. Mining has increased rainforest loss up to 70km beyond lease boundaries, causing nearly 11,670 km of deforestation between 2005 to 2015. Up to 9% of gold mining occurs outside of these regulated lease boundaries. Other gold mining impacts, particularly in aquatic systems with residual cyanide or mercury (used in

9690-431: The most venerated woman in Egyptian history", was thought by some scholars such as Flinders Petrie to be of Nubian origin because she is most often depicted with black skin. The mummy of Ahmose-Nefertari 's father, Seqenenre Tao , has been described as presenting "tightly curled, woolly hair", with "a slight build and strongly Nubian features". Some modern scholars also believe that in some depictions, her skin color

9804-711: The neighbouring Free State province were found shortly thereafter, driving significant development in the region with the establishment of the Free State goldfields . Also known as the Yukon Gold Rush , brought prospectors from around the world to the Klondike region of the Yukon territory in Canada . The Klondike Gold Rush began in 1896, when gold was discovered in Bonanza Creek ,

9918-483: The next 600 years. Old Kingdom Egyptian dynasties (4th to 6th) controlled uninhabited Lower Nubia and raided Upper Nubia. The pre-Kerma developed into the Middle phase Kerma group. Some A-group people (transitioning to C-group) settled the area and co-existed with the pre-Kerma group. Like other Nubian groups, the two groups made an abundance of red pottery with black tops, though each group made different shapes. Traces of

10032-413: The old bucket line . This has improved the chances of finding gold. Smaller dredges with 50-to-100-millimetre (2 to 4 in) suction tubes are used to sample areas behind boulders and along potential pay streaks, until "colour" (gold) appears. Other larger scale dredging operations take place on exposed river gravel bars at seasonal low water. These operations typically use a land based excavator to feed

10146-599: The oldest open-air hut in the world) and diverse hunting and gathering loci some 50,000 years old". In southern Nubia (near modern Khartoum) from the ninth to the sixth millennia cal BC, Khartoum Mesolithic fisher-hunter-gatherers produced sophisticated pottery. By 5000 BC, the people who inhabited what is now called Nubia participated in the Neolithic Revolution . The Sahara became drier and people began to domesticate sheep, goats, and cattle. Saharan rock reliefs depict scenes that have been thought to suggest

10260-691: The origins of the Kushite kings of the 25th Dynasty: some scholars believe they were Nubian officials that learned "state level organization" by administering Egyptian-held Nubia from 1500 to 1070 BC, such as the rebel Viceroy of Kush, Panehesy, who ruled Upper Nubia and some of Lower Nubia after Egyptian forces withdrew. Other scholars believe they are descended from families of the Egyptianized Nubian elite supported by Egyptian priests or settlers. Children of elite Nubian families were sent to be educated in Egypt then returned to Kush to be appointed in bureaucratic positions to ensure their loyalty. During

10374-425: The outcroppings on the creek that is now named for him and turned out later to be the site of the richest hard-rock veins in the region. Early exploratory parties of Chinese and Italians in the upper Bridge River basin were driven out by Chief Hunter Jack , who himself had a secret placer mine somewhere in the region, believed to be in upper Tyaughton Creek . and whose big-game hunting territory this also was. During

10488-649: The partition of Nubia, which was split into the northern half conquered by the Ottomans and the southern half by the Sennar sultanate , in the sixteenth century, but also a rapid Islamization and partial Arabization of the Nubian people . Nubia was reunited with the Khedivate of Egypt in the nineteenth century. Today, the region of Nubia is split between Egypt and Sudan. The primarily archaeological science dealing with ancient Nubia

10602-688: The possible respiratory problems that could be acquired, individuals may be exposed to hazardous chemicals used in gold extraction such as mercury and cyanide. These chemicals pose risks to gold miners, communities, and wildlife; resulting in further medical problems involving neurological disorders and waterborne diseases . Gold mining in some regions has been associated with conflicts over land rights, labour rights violations, and exploitation of vulnerable populations, including Indigenous peoples and artisanal miners. Mining activities can damage or destroy cultural heritage sites, artifacts, and sacred areas; further impacting cultural identities and heritages. In

10716-513: The presence of a cattle cult , typical of those seen throughout parts of Eastern Africa and the Nile Valley even to this day. Nubian rock art depicts hunters using bows and arrows in the neolithic period, which is a precursor to Nubian archer culture in later times. Megaliths discovered at Nabta Playa are early examples of what seems to be one of the world's first astronomical devices, predating Stonehenge by almost 2,000 years. This complexity as expressed by different levels of authority within

10830-407: The recovery of gold from ore), can be highly toxic to people and wildlife even at relatively low concentrations. Illegal gold mining exacerbates the ecological vulnerability of the remaining forest ultimately leading to permanent forest loss. Gold mining clears native forests for mineral extraction, but also indirectly facilitates access to more land and further clearing. Rainforest recovery rates are

10944-687: The river as Nehasyu. From Aswan , the southern limit of Egyptian control at the time, Egyptians imported gold, incense, ebony, copper, ivory, and exotic animals from tropical Africa through Nubia. Relations between the Egyptians and Nubians showed peaceful cultural interchange, cooperation, and mixed marriages. Nubian bowmen that settled at Gebelein during the First Intermediate Period married Egyptian women, were buried in Egyptian style, and eventually could not be distinguished from Egyptians. Older scholarship noted that some Egyptian pharaohs may have had Nubian ancestry. Richard Loban expressed

11058-634: The royal palaces and tombs in Thebes and the surrounding areas, the Medjay were deployed throughout Upper and Lower Egypt; they were even used during Kamose 's campaign against the Hyksos and became instrumental in turning the Egyptian state into a military power. After the First Intermediate Period of Egypt , the Medjay district was no longer mentioned in written records. From the Middle Kerma phase,

11172-540: The sluice box. A rocker box uses less water than a sluice box and is well suited for areas where water is limited. A rocking motion provides the water movement needed for the gravity separation of gold in placer material. Rocker boxes gained popularity during the California Gold Rush in the 19th century and remain in use today. Although simple and inexpensive, it is not efficient as the previously discussed mining techniques . The dominant method for refining gold

11286-523: The society there likely formed the basis for the structure of both the Neolithic society at Nabta and the Old Kingdom of Egypt . American anthropologist, Joseph Vogel wrote that: "The period when sub-Saharan Africa was most influential in Egypt was a time when neither Egypt, as we understand it culturally, nor the Sahara, as we understand it geographically, existed. Populations and cultures now found south of

11400-467: The surrounding rock or sediments. Unlike hard-rock mining, which involves excavating solid rock formations, water or dredging is used to extract the gold. Using a sluice box to extract gold from placer deposits has long been a very common practice in prospecting and small-scale mining. Sluices work on the principle that heavier particles will sink to the bottom of a stream, while those that are lighter will be carried downstream and expelled. A sluice box

11514-703: The view that Mentuhotep II of the 11th Dynasty "was quite possibly of Nubian origin" and cited historical evidence which mentioned that Amenemhet I , founder of the 12th Dynasty, "had a Ta Seti or Nubian mother". Dietrich Wildung has argued that Nubian features were common in Egyptian iconography since the pre-dynastic era and that several pharaohs such as Khufu and Mentuhotep II were represented with these Nubian features. Frank Yurco wrote that "Egyptian rulers of Nubian ancestry had become Egyptians culturally; as pharaohs, they exhibited typical Egyptian attitudes and adopted typical Egyptian policies". Yurco noted that some Middle Kingdom rulers, particularly some pharaohs of

11628-587: The world's gold. Sometimes open-pit mining is used, such as at the Fort Knox Mine in central Alaska. Barrick Gold Corporation has one of the largest open-pit gold mines in North America located on its Goldstrike mine property in north eastern Nevada. Other gold mines use underground mining, where the ore is extracted through tunnels or shafts. South Africa has the world's deepest hard rock gold mine up to 3,900 metres (12,800 ft) underground. At such depths,

11742-711: The world, the Grasberg mine in Papua, Indonesia, is primarily a copper mine. Gold panning , or simply panning , is a form of placer mining and traditional mining that extracts gold from a placer deposit using a pan. The process is one of the simplest ways to extract gold, and is popular with geology enthusiasts especially because of its low cost and relative simplicity. The first recorded instances of placer mining are from ancient Rome , where gold and other precious metals were extracted from streams and mountainsides using sluices and panning ( ruina montium ). Placer mining

11856-663: Was China with 368.3 tonnes of gold mined in that year. The second-largest producer of gold was Russia where 331.1 tonnes was mined in the same year, followed by Australia with 327.8 tonnes. In 2023, the annual gold demand of 4,448 tonnes was 5% below that of 2022. The total gold demand in 2023 was the highest at 4,899 tonnes. Despite its decreasing content in ores, gold production is increasing. This increase can be achieved through ever larger-scale industrial installations as well as innovations, especially in hydrometallurgy . Hard rock mining extracts gold encased in rock, rather than fragments in loose sediment, and produces most of

11970-503: Was "sometimes portrayed by later generations as having been black, although her coffin portrait gives her the typical light yellow skin of women." In 2009, Egyptologist Elena Vassilika, noting that in a wooden statuette of the queen (now at the Museo Egizio ) the face is painted black but the arms and feet are light in color, argued that the reason for the black coloring in that case was religious and not genetic. In 1098–1088 BC, Thebes

12084-532: Was "the scene of a civil war-like conflict between the High Priest of Amun of Thebes Amenhotep and the Viceroy of Kush Panehesy (= the Nubian)". It was chaotic and many tombs were plundered. Instead of sending soldiers to restore order, Ramesses XI put Panehesy in control of that area's military and appointed him Director of Granaries. Panehesy stationed his troops in Thebes to protect the city from thieves, but it resembled

12198-501: Was centered at Kerma and Shaat was centered on Sai island. Bonnet posits that Kush actually ruled all of Upper Nubia, since "royal" graves were much larger in Kush than Shaat and Egyptian texts other than the Execration lists only refer to Kush (and not Shaat). C-group Nubians resettled Lower Nubia by 2400 BC. As trade between Egypt and Nubia increased, so did wealth and stability. Nubia

12312-506: Was discovered in 1961. Official estimates indicate that total world gold production since the beginning of civilization has been around 6,352,216,000 troy ounces (197,576.0 t) and total gold production in Nevada is 1.1% of that, ranking Nevada as one of the Earth's primary gold-producing regions. World gold production was 3,612 tonnes in 2022. As of 2020 , the world's largest gold producer

12426-505: Was divided into a series of small kingdoms. There is debate over whether the C-group people, who flourished from 2500 BC to 1500 BC, were another internal evolution or invaders. O'Connor states "a transition from A group into a later culture, the C-group, can be traced" and the C-group culture was typical of Lower Nubia from 2400 to 1650 BC. Although they lived in close proximity to each other, Nubians did not acculturate much to Egyptian culture. Notable exceptions include C-group Nubians during

12540-417: Was independent and increasingly powerful during this time. These Egyptian garrisons seemed to peacefully coexist with the local Nubian people, though they did not interact much with them. Medjay was the name given by ancient Egypt to nomadic desert dwellers from east of the Nile river. The term was used variously to describe a location, the Medjay people, or their role/job in the kingdom. They became part of

12654-580: Was invaded and annexed to Egypt, ruled by the Greeks and Romans . This territory was known in the Greco-Roman world as Dodekaschoinos . Kush's collapse in the fourth century AD was preceded by an invasion from the Ethiopian Kingdom of Aksum and the rise of three Christian kingdoms: Nobatia , Makuria and Alodia . Makuria and Alodia lasted for roughly a millennium. Their eventual decline started not only

12768-569: Was mined extensively. The ancient Sumerians , around 2500 BCE, developed sophisticated techniques for extracting gold from alluvial deposits and underground mines. These techniques included the use of sluice boxes. Evidence suggests that Nubia had sporadic access to gold nuggets during the Neolithic and Prehistoric Period . Gold mining in Egypt involved both surface mining such as panning for gold in riverbeads and underground mining, where tunnels were dug to extract gold-bearing quartz veins. During

12882-412: Was named the new High Priest of Thebes (and effectively King of Southern Egypt) and Paiankh was named the new Viceroy of Kush. Paiankh recaptured former Egyptian holdings in Lower Nubia as far as the second Nile cataract, but could not defeat Panehesy in Lower Nubia, who ruled the area until his death. Herihor's descendants became rulers of Egypt's 21st and 22nd Dynasties. There are competing theories on

12996-552: Was the burial place of the ancestors of the Twenty-Fifth Dynasty." The early el-Kurru burials resemble Nubian Kerma/C-group traditions (contracted body, circular stone structures, burial on a bed). However, by 880–815 BC, Nubian burials at el-Kurru became more Egyptian in style with "mastabas, or pyramid on mastabas, chapels, and rectangular enclosures". Alara, the first el-Kurru prince, and his successor, Kashta , were buried at el-Kurru. Later documents mention Alara as
