Mary Beard points to
680-698: 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
816-716: 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
952-479: A free path to reestablish his own power. In 83 BC he made his second march on Rome and began a time of terror: thousands of nobles, knights and senators were executed. Sulla held two dictatorships and one more consulship, which began the crisis and decline of Roman Republic. In the mid-1st century BC, Roman politics were restless. Political divisions in Rome split into one of two groups, populares (who hoped for

"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
1224-650: A half century after these events, Carthage was left humiliated and the Republic's focus was now directed towards the Hellenistic kingdoms of Greece and revolts in Hispania . However, Carthage, having paid the war indemnity, felt that its commitments and submission to Rome had ceased, a vision not shared by the Roman Senate . The Third Punic War began when Rome declared war against Carthage in 149 BC. Carthage resisted well at

Titus died of fever in 81 AD, and was succeeded by his brother Domitian . As emperor, Domitian showed the characteristics of a tyrant . He ruled for fifteen years, during which time he acquired a reputation for self-promotion as a living god. He constructed at least two temples in honour of Jupiter,
1496-610: A large proletariat often of impoverished farmers. The latter groups supported the Catilinarian conspiracy —a resounding failure since the consul Marcus Tullius Cicero quickly arrested and executed the main leaders. Gaius Julius Caesar reconciled the two most powerful men in Rome: Marcus Licinius Crassus , who had financed much of his earlier career, and Crassus' rival, Gnaeus Pompeius Magnus (anglicised as Pompey), to whom he married his daughter . He formed them into

While Paulinus and his troops were massacring druids in Mona,
1904-488: 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
2040-686: A military leader to defeat the Cimbri and the Teutones , who were threatening Rome. After Marius's retirement, Rome had a brief peace, during which the Italian socii ("allies" in Latin) requested Roman citizenship and voting rights. The reformist Marcus Livius Drusus supported their legal process but was assassinated, and the socii revolted against the Romans in the Social War . At one point both consuls were killed; Marius
2176-644: A new informal alliance including himself, the First Triumvirate ("three men"). Caesar's daughter died in childbirth in 54 BC, and in 53 BC, Crassus invaded Parthia and was killed in the Battle of Carrhae ; the Triumvirate disintegrated. Caesar conquered Gaul , obtained immense wealth, respect in Rome and the loyalty of battle-hardened legions. He became a threat to Pompey and was loathed by many optimates . Confident that Caesar could be stopped by legal means, Pompey's party tried to strip Caesar of his legions,
2312-510: A pair of tribunes who attempted to pass land reform legislation that would redistribute the major patrician landholdings among the plebeians. Both brothers were killed and the Senate passed reforms reversing the Gracchi brother's actions. This led to the growing divide of the plebeian groups ( populares ) and equestrian classes ( optimates ). Gaius Marius soon become a leader of the Republic, holding
2448-527: A period of turbulence. Archaeological evidence implies some degree of large-scale warfare. According to tradition and later writers such as Livy , the Roman Republic was established c. 509 BC , when the last of the seven kings of Rome, Tarquin the Proud , was deposed and a system based on annually elected magistrates and various representative assemblies was established. A constitution set
2584-564: A prelude to Caesar's trial, impoverishment, and exile. To avoid this fate, Caesar crossed the Rubicon River and invaded Rome in 49 BC. The Battle of Pharsalus was a brilliant victory for Caesar and in this and other campaigns, he destroyed all of the optimates leaders: Metellus Scipio , Cato the Younger , and Pompey's son, Gnaeus Pompeius . Pompey was murdered in Egypt in 48 BC. Caesar
2720-438: 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. Ancient Rome In modern historiography , ancient Rome
2856-603: A revolt in Mauretania and the Bar Kokhba revolt in Judea. This was the last large-scale Jewish revolt against the Romans, and was suppressed with massive repercussions in Judea. Hundreds of thousands of Jews were killed. Hadrian renamed the province of Judea " Provincia Syria Palaestina ", after one of Judea's most hated enemies. He constructed fortifications and walls, like the celebrated Hadrian's Wall which separated Roman Britannia and

They landed on the banks of the Tiber River and a woman travelling with them, Roma, torched their ships to prevent them leaving again. They named the settlement after her. The Roman poet Virgil recounted this legend in his classical epic poem the Aeneid , where the Trojan prince Aeneas is destined to found a new Troy. Literary and archaeological evidence
3264-671: A series of checks and balances , and a separation of powers . The most important magistrates were the two consuls , who together exercised executive authority such as imperium , or military command. The consuls had to work with the Senate , which was initially an advisory council of the ranking nobility, or patricians , but grew in size and power. Other magistrates of the Republic include tribunes , quaestors , aediles , praetors and censors . The magistracies were originally restricted to patricians , but were later opened to common people, or plebeians . Republican voting assemblies included

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.,
3944-418: 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
4080-429: 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
4216-415: 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

Long after the abolition of the Roman monarchy, a vestigial rex sacrorum was retained to exercise the monarch's former priestly functions. The Romans believed that their monarchy was elective, with seven legendary kings who were largely unrelated by blood. Evidence of Roman expansion is clear in the sixth century BC; by its end, Rome controlled
4488-616: 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
4624-436: 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

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,
5168-586: Is the Roman civilisation from the founding of the Italian city of Rome in the 8th century BC to the collapse of the Western Roman Empire in the 5th century AD. It encompasses the Roman Kingdom (753–509 BC), the Roman Republic (509–27 BC), and the Roman Empire (27 BC–476 AD) until the fall of the western empire. Ancient Rome began as an Italic settlement, traditionally dated to 753 BC, beside

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
5440-519: 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

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
10200-537: The changes to the calendar promoted by Caesar , and the month of August is named after him. Augustus brought a peaceful and thriving era to Rome, known as Pax Augusta or Pax Romana . Augustus died in 14 AD, but the empire's glory continued after his era. The Julio-Claudians continued to rule Rome after Augustus' death and remained in power until the death of Nero in 68 AD. Influenced by his wife, Livia Drusilla , Augustus appointed her son from another marriage, Tiberius , as his heir. The Senate agreed with
10336-466: The character Aeneas , a common culture is attested to archaeologically. Attested to reciprocal rights of marriage and citizenship between Latin cities—the Jus Latii —along with shared religious festivals, further indicate a shared culture. By the end of the 6th century, most of this area had become dominated by the Romans. By the end of the sixth century, Rome and many of its Italian neighbours entered
10472-465: The city's sole founder. The area of his initial settlement on the Palatine Hill was later known as Roma Quadrata ("Square Rome"). The story dates at least to the third century BC, and the later Roman antiquarian Marcus Terentius Varro placed the city's foundation to 753 BC. Another legend, recorded by Greek historian Dionysius of Halicarnassus , says that Prince Aeneas led a group of Trojans on
10608-785: The death of Tiberius, and, with belated support from the senators, proclaimed his uncle Claudius as the new emperor. Claudius was not as authoritarian as Tiberius and Caligula. Claudius conquered Lycia and Thrace ; his most important deed was the beginning of the conquest of Britannia . Claudius was poisoned by his wife, Agrippina the Younger in 54 AD. His heir was Nero , son of Agrippina and her former husband, since Claudius' son Britannicus had not reached manhood upon his father's death. Nero sent his general, Suetonius Paulinus , to invade modern-day Wales , where he encountered stiff resistance. The Celts there were independent, tough, resistant to tax collectors, and fought Paulinus as he battled his way across from east to west. It took him
10744-462: The destruction of republican values, but on the other hand, they boosted Rome's status as the central power in the Mediterranean region. While Caligula and Nero are usually remembered in popular culture as dysfunctional emperors, Augustus and Claudius are remembered as successful in politics and the military. This dynasty instituted imperial tradition in Rome and frustrated any attempt to reestablish
10880-579: The edict as a fundamental turning point, after which Rome was "effectively a new state masquerading under an old name". Macrinus conspired to have Caracalla assassinated by one of his soldiers during a pilgrimage to the Temple of the Moon in Carrhae, in 217 AD. Macrinus assumed power, but soon removed himself from Rome to the east and Antioch. His brief reign ended in 218, when the youngster Bassianus, high priest of
11016-432: 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
11152-462: The emperors all the executive powers of government. Gibbon declared the rule of these "Five Good Emperors" the golden era of the Empire. During this time, Rome reached its greatest territorial extent. Commodus , son of Marcus Aurelius, became emperor after his father's death. He is not counted as one of the Five Good Emperors, due to his direct kinship with the latter emperor; in addition, he
11288-519: The end of the Triumvirate, Antony was living in Ptolemaic Egypt , ruled by his lover, Cleopatra VII . Antony's affair with Cleopatra was seen as an act of treason, since she was queen of another country. Additionally, Antony adopted a lifestyle considered too extravagant and Hellenistic for a Roman statesman. Following Antony's Donations of Alexandria , which gave to Cleopatra the title of " Queen of Kings ", and to Antony's and Cleopatra's children
11424-762: 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
11560-492: The field. However, he became ill and died in 211 AD, at the age of 65. Upon the death of Severus, his sons Caracalla and Geta were made emperors. Caracalla had his brother, a youth, assassinated in his mother's arms, and may have murdered 20,000 of Geta's followers. Like his father, Caracalla was warlike. He continued Severus' policy and gained respect from the legions. Knowing that the citizens of Alexandria disliked him and were denigrating his character, Caracalla served
11696-700: The first graves in the Esquiline Hill 's necropolis, along with a clay and timber wall on the bottom of the Palatine Hill dating to the middle of the 8th century BC. Starting from c. 650 BC , the Romans started to drain the valley between the Capitoline and Palatine Hills, where today sits the Roman Forum . By the sixth century BC, the Romans were constructing the Temple of Jupiter Optimus Maximus on
11832-516: The first of his seven consulships (an unprecedented number) in 107 BC by arguing that his former patron Quintus Caecilius Metellus Numidicus was not able to defeat and capture the Numidian king Jugurtha . Marius then started his military reform: in his recruitment to fight Jugurtha, he levied the very poor (an innovation), and many landless men entered the army. Marius was elected for five consecutive consulships from 104 to 100 BC, as Rome needed
11968-564: The first persecutor of Christians and for the Great Fire of Rome , rumoured to have been started by the emperor himself. A conspiracy against Nero in 65 AD under Calpurnius Piso failed, but in 68 AD the armies under Julius Vindex in Gaul and Servius Sulpicius Galba in modern-day Spain revolted. Deserted by the Praetorian Guards and condemned to death by the senate, Nero killed himself. As Roman provinces were being established throughout
12104-465: The first strike but could not withstand the attack of Scipio Aemilianus , who entirely destroyed the city, enslaved all the citizens and gained control of that region, which became the province of Africa . All these wars resulted in Rome's first overseas conquests (Sicily, Hispania and Africa) and the rise of Rome as a significant imperial power. After defeating the Macedonian and Seleucid Empires in
12240-469: The frontier legions to save them. The legions of three frontier provinces— Britannia , Pannonia Superior , and Syria —resented being excluded from the " donative " and replied by declaring their individual generals to be emperor. Lucius Septimius Severus Geta, the Pannonian commander, bribed the opposing forces, pardoned the Praetorian Guards and installed himself as emperor. He and his successors governed with
12376-694: 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
12512-553: 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
12648-750: 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
12784-469: The imperial dignity. Pertinax, a member of the senate who had been one of Marcus Aurelius's right-hand men, was the choice of Laetus, and he ruled vigorously and judiciously. Laetus soon became jealous and instigated Pertinax's murder by the Praetorian Guard, who then auctioned the empire to the highest bidder, Didius Julianus, for 25,000 sesterces per man. The people of Rome were appalled and appealed to
12920-433: The increased reliance on foreign slaves and the growth of latifundia reduced the availability of paid work. Income from war booty, mercantilism in the new provinces, and tax farming created new economic opportunities for the wealthy, forming a new class of merchants, called the equestrians . The lex Claudia forbade members of the Senate from engaging in commerce, so while the equestrians could theoretically join
13056-584: 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
13192-756: The laws. He died in 161 AD. Marcus Aurelius , known as the Philosopher, was the last of the Five Good Emperors . He was a stoic philosopher and wrote the Meditations . He defeated barbarian tribes in the Marcomannic Wars as well as the Parthian Empire . His co-emperor, Lucius Verus , died in 169 AD, probably from the Antonine Plague , a pandemic that killed nearly five million people through
13328-682: The legions' support. The changes on coinage and military expenditures were the root of the financial crisis that marked the Crisis of the Third Century . Severus was enthroned after invading Rome and having Didius Julianus killed. Severus attempted to revive totalitarianism and, addressing the Roman people and Senate, praised the severity and cruelty of Marius and Sulla, which worried the senators. When Parthia invaded Roman territory, Severus successfully waged war against that country. Notwithstanding this military success, Severus failed in invading Hatra ,
13464-461: 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
13600-663: 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
13736-711: 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 ,
13872-413: 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
14008-534: The path to the victory a long and difficult one for the Roman Republic . Despite this, after more than 20 years of war, Rome defeated Carthage and a peace treaty was signed. Among the reasons for the Second Punic War was the subsequent war reparations Carthage acquiesced to at the end of the First Punic War. The war began with the audacious invasion of Hispania by Hannibal , who marched through Hispania to
14144-752: The populace and the legions. Augustus intended to extend the Roman Empire to the whole known world, and in his reign, Rome conquered Cantabria , Aquitania , Raetia , Dalmatia , Illyricum and Pannonia . Under Augustus' reign, Roman literature grew steadily in what is known as the Golden Age of Latin Literature . Poets like Virgil , Horace , Ovid and Rufus developed a rich literature, and were close friends of Augustus. Along with Maecenas , he sponsored patriotic poems, such as Virgil's epic Aeneid and historiographical works like those of Livy . Augustus continued
14280-688: 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
14416-407: 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
14552-400: The regal titles to the newly conquered Eastern territories, war between Octavian and Antony broke out . Octavian annihilated Egyptian forces in the Battle of Actium in 31 BC. Antony and Cleopatra committed suicide . Now Egypt was conquered by the Roman Empire. In 27 BC and at the age of 36, Octavian was the sole Roman leader. In that year, he took the name Augustus . That event
14688-546: The revitalised Persia and also the Germanic peoples , who invaded Gaul. His losses generated dissatisfaction among his soldiers, and some of them murdered him during his Germanic campaign in 235 AD. A disastrous scenario emerged after the death of Alexander Severus : the Roman state was plagued by civil wars, external invasions , political chaos, pandemics and economic depression . The old Roman values had fallen, and Mithraism and Christianity had begun to spread through
14824-732: The siege, of whom a majority were Jewish. 97,000 were captured and enslaved , including Simon bar Giora and John of Giscala . Many fled to areas around the Mediterranean. Vespasian was a general under Claudius and Nero and fought as a commander in the First Jewish-Roman War . Following the turmoil of the Year of the Four Emperors , in 69 AD, four emperors were enthroned in turn: Galba , Otho , Vitellius , and, lastly, Vespasian, who crushed Vitellius' forces and became emperor. He reconstructed many buildings which were uncompleted, like
14960-540: 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
15096-491: The son of the deified. In the same year, Octavian and Antony defeated both Caesar's assassins and the leaders of the Liberatores , Marcus Junius Brutus and Gaius Cassius Longinus , in the Battle of Philippi . The Second Triumvirate was marked by the proscriptions of many senators and equites : after a revolt led by Antony's brother Lucius Antonius , more than 300 senators and equites involved were executed, although Lucius
15232-514: The succession, and granted to Tiberius the same titles and honours once granted to Augustus: the title of princeps and Pater patriae , and the Civic Crown . However, Tiberius was not an enthusiast for political affairs: after agreement with the Senate, he retired to Capri in 26 AD, and left control of the city of Rome in the hands of the praetorian prefect Sejanus (until 31 AD) and Macro (from 31 to 37 AD). Tiberius died (or
15368-429: The support of the people) and optimates (the "best", who wanted to maintain exclusive aristocratic control). Sulla overthrew all populist leaders and his constitutional reforms removed powers (such as those of the tribune of the plebs ) that had supported populist approaches. Meanwhile, social and economic stresses continued to build; Rome had become a metropolis with a super-rich aristocracy, debt-ridden aspirants, and
15504-480: The supreme deity in Roman religion . He was murdered following a plot within his own household. Following Domitian's murder, the Senate rapidly appointed Nerva as Emperor. Nerva had noble ancestry, and he had served as an advisor to Nero and the Flavians. His rule restored many of the traditional liberties of Rome's upper classes, which Domitian had over-ridden. The Nerva–Antonine dynasty from 96 AD to 192 AD included
15640-624: The surface has led to more complex extraction processes such as pit mining and gold cyanidation . In 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
15776-467: 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
15912-445: The temple of the Sun at Emesa, and supposedly illegitimate son of Caracalla, was declared Emperor by the disaffected soldiers of Macrinus. He adopted the name of Antoninus but history has named him after his Sun god Elagabalus , represented on Earth in the form of a large black stone. An incompetent and lascivious ruler, Elagabalus offended all but his favourites. Cassius Dio , Herodian and
16048-460: The tribes of modern-day East Anglia staged a revolt led by queen Boadicea of the Iceni . The rebels sacked and burned Camulodunum , Londinium and Verulamium (modern-day Colchester , London and St Albans respectively) before they were crushed by Paulinus . Boadicea, like Cleopatra before her, committed suicide to avoid the disgrace of being paraded in triumph in Rome. Nero is widely known as
16184-486: The tribes of modern-day Scotland. Hadrian promoted culture, especially the Greek. He forbade torture and humanised the laws. His many building projects included aqueducts, baths, libraries and theatres; additionally, he travelled nearly every province in the Empire to review military and infrastructural conditions. Following Hadrian's death in 138 AD, his successor Antoninus Pius built temples, theatres, and mausoleums, promoted
16320-562: The weighing noticed that the Gauls were using false scales. The Romans then took up arms and defeated the Gauls. Their victorious general Camillus remarked "With iron, not with gold, Rome buys her freedom." The Romans gradually subdued the other peoples on the Italian peninsula, including the Etruscans . The last threat to Roman hegemony in Italy came when Tarentum , a major Greek colony, enlisted
16456-587: 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,
16592-493: The world's largest gold bar , weighing 250 kilograms (8,000 ozt), and representing a 2016 value of about 1.1 billion yen (US$ 9.7 million). The bar obtained an official Guinness record certificate for "The largest manufactured pure gold bar": Gold mining Gold mining is the extraction of gold by mining . 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
16728-657: The world's population at the time. The Roman state evolved from an elective monarchy to a classical republic and then to an increasingly autocratic military dictatorship during the Empire. Ancient Rome is often grouped into classical antiquity together with ancient Greece , and their similar cultures and societies are known as the Greco-Roman world . Ancient Roman civilisation has contributed to modern language, religion, society, technology, law, politics, government, warfare, art, literature, architecture, and engineering. Rome professionalised and expanded its military and created
16864-711: 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
17000-663: 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
17136-636: Was Josephus' sponsor and Pliny dedicated his Naturalis Historia to Titus, son of Vespasian. Vespasian sent legions to defend the eastern frontier in Cappadocia , extended the occupation in Britannia (modern-day England, Wales and southern Scotland ) and reformed the tax system. He died in 79 AD. Titus became emperor in 79. He finished the Flavian Amphitheater, using war spoils from the First Jewish-Roman War, and hosted victory games that lasted for
17272-470: Was appointed to command the army together with Lucius Julius Caesar and Lucius Cornelius Sulla . By the end of the Social War, Marius and Sulla were the premier military men in Rome and their partisans were in conflict, both sides jostling for power. In 88 BC, Sulla was elected for his first consulship and his first assignment was to defeat Mithridates VI of Pontus , whose intentions were to conquer
17408-502: Was campaigning in Greece. He seized power along with the consul Lucius Cornelius Cinna and killed the other consul, Gnaeus Octavius , achieving his seventh consulship. Marius and Cinna revenged their partisans by conducting a massacre. Marius died in 86 BC, due to age and poor health, just a few months after seizing power. Cinna exercised absolute power until his death in 84 BC. After returning from his Eastern campaigns, Sulla had
17544-506: 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
17680-490: Was killed) in 37 AD. The male line of the Julio-Claudians was limited to Tiberius' nephew Claudius , his grandson Tiberius Gemellus and his grand-nephew Caligula . As Gemellus was still a child, Caligula was chosen to rule the empire. He was a popular leader in the first half of his reign, but became a crude and insane tyrant in his years controlling government. The Praetorian Guard murdered Caligula four years after
17816-525: Was militarily passive. Cassius Dio identifies his reign as the beginning of Roman decadence : "(Rome has transformed) from a kingdom of gold to one of iron and rust." Commodus was killed by a conspiracy involving Quintus Aemilius Laetus and his wife Marcia in late 192 AD. The following year is known as the Year of the Five Emperors , during which Helvius Pertinax , Didius Julianus , Pescennius Niger , Clodius Albinus and Septimius Severus held
17952-569: 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
18088-570: Was no chance of a return to the Roman Republic , and so a new emperor had to arise. After the turmoil in the Year of the Four Emperors , Titus Flavius Vespasianus (anglicised as Vespasian) took control of the empire and established a new dynasty. Under the Flavians, Rome continued its expansion, and the state remained secure. Under Trajan, the Roman Empire reached the peak of its territorial expansion. Rome's dominion now spanned 5.0 million square kilometres (1.9 million square miles). The most significant military campaign undertaken during
18224-602: Was now pre-eminent over Rome: in five years he held four consulships, two ordinary dictatorships, and two special dictatorships, one for perpetuity. He was murdered in 44 BC, on the Ides of March by the Liberatores . Caesar's assassination caused political and social turmoil in Rome; the city was ruled by his friend and colleague, Marcus Antonius . Soon afterward, Octavius , whom Caesar adopted through his will, arrived in Rome. Octavian (historians regard Octavius as Octavian due to
18360-549: Was spared. The Triumvirate divided the Empire among the triumvirs: Lepidus was given charge of Africa , Antony, the eastern provinces, and Octavian remained in Italia and controlled Hispania and Gaul . The Second Triumvirate expired in 38 BC but was renewed for five more years. However, the relationship between Octavian and Antony had deteriorated, and Lepidus was forced to retire in 36 BC after betraying Octavian in Sicily . By
18496-482: Was succeeded by the general Trajan . Trajan is credited with the restoration of traditional privileges and rights of commoner and senatorial classes, which later Roman historians claim to have been eroded during Domitian's autocracy. Trajan fought three Dacian wars , winning territories roughly equivalent to modern-day Romania and Moldova . He undertook an ambitious public building program in Rome, including Trajan's Forum , Trajan's Market and Trajan's Column , with
