A town is a type of a human settlement . Towns are generally larger than villages and smaller than cities , though the criteria to distinguish between them vary considerably in different parts of the world.
108-628: Capiibary is a town in the San Pedro department of Paraguay . The city gets its name from the Capiibary River, which was named Capiĭbarĭ (compound from capiĭbá·r " capybara " and ĭ "water, river") in Classical Guarani by the natives due to the abundance of these animals in the river. With time, the original pronunciation got mixed together with the Spanish reading of the name, thus producing
216-408: A Millionenstadt , a city with anywhere between one and five million inhabitants (such as Cologne , Munich , Hamburg and Berlin ). Also, a city with more than five million inhabitants is often referred to as a Megastadt (commonly translated as megacity ). Historically, many settlements became a Stadt by being awarded a Stadtrecht in medieval times. In modern German language use,
324-537: A further 17 towns , which have merged with a municipal parish ( vallasisene linn ). In Finland, there is no distinction between a town and a city as the word kaupunki is used for both bigger and smaller settlements, which are bigger than villages and boroughs; although when talking about the word town , the word pikkukaupunki is used ( pikku means 'little' or 'small'). There are over one hundred municipal towns in Finland. From an administrative standpoint,
432-519: A palisade or stockade instead. In the Netherlands, this space was a garden, more specifically those of the wealthy, which had a high fence or a wall around them (like the garden of the palace of Het Loo in Apeldoorn , which was the model for the privy garden of William III and Mary II at Hampton Court ). In Old Norse tún means a (grassy) place between farmhouses, and the word is still used with
540-556: A higher degree of services . (There are a few exceptions, when towns of fewer than 50,000 people gained the status: Érd , Hódmezővásárhely , Salgótarján and Szekszárd ) As of middle 2013, there are only 23 such towns in Hungary. The 2011 Census of India defines towns of two types: statutory town and census town . Statutory town is defined as all places with a municipality , corporation , cantonment board or notified town area committee. Census towns are defined as places that satisfy
648-590: A higher tier of local government, larger towns and cities may have the status of a kreisfreie Stadt , combining both the powers of a municipality and a district. Designations in different states are as diverse as e.g. in Australian States and Territories, and differ from state to state. In some German states, the words Markt ('market'), Marktflecken (both used in southern Germany) or Flecken ('spot'; northern Germany e.g. in Lower Saxony ) designate
756-636: A hopper and a shaking screen or trommel which frees the desired minerals from the waste gravel. The minerals are then concentrated using sluices or jigs. Large drills are used to sink shafts, excavate stopes, and obtain samples for analysis. Trams are used to transport miners, minerals and waste. Lifts carry miners into and out of mines, and move rock and ore out, and machinery in and out, of underground mines. Huge trucks, shovels and cranes are employed in surface mining to move large quantities of overburden and ore. Processing plants use large crushers, mills, reactors, roasters and other equipment to consolidate
864-875: A mass of actual rock. Both types of ore deposit, placer or lode, are mined by both surface and underground methods. Some mining, including much of the rare earth elements and uranium mining , is done by less-common methods, such as in-situ leaching : this technique involves digging neither at the surface nor underground. The extraction of target minerals by this technique requires that they be soluble, e.g., potash , potassium chloride , sodium chloride , sodium sulfate , which dissolve in water. Some minerals, such as copper minerals and uranium oxide , require acid or carbonate solutions to dissolve. Explosives in Mining Explosives have been used in surface mining and sub-surface mining to blast out rock and ore intended for processing. The most common explosive used in mining
972-426: A mining operation. Once the analysis determines a given ore body is worth recovering, development begins to create access to the ore body. The mine buildings and processing plants are built, and any necessary equipment is obtained. The operation of the mine to recover the ore begins and continues as long as the company operating the mine finds it economical to do so. Once all the ore that the mine can produce profitably
1080-503: A more sustainable future, the demand for metals is set to skyrocket. Between 2022 and 2050, an estimated 7 billion metric tons of metals will need to be extracted. Steel will account for the largest portion of this total at 5 billion tons, followed by aluminum at 950 million tons, copper at 650 million tons, graphite at 170 million tons, nickel at 100 million tons, and other metals. Notably, the energy expenditure required to extract these metals will soon surpass that of coal mining, highlighting
1188-426: A municipality must have at least 3,000 inhabitants to have the right to request the town title. Market towns usually have between 500 and 4,000 inhabitants, with median and average both around 1,000. In Denmark, in many contexts no distinction is made between "city", "town" and "village"; all three translate as by . In more specific use, for small villages and hamlets the word landsby (meaning 'country town')
SECTION 10
#17329314817981296-428: A rock or mineral that contains valuable constituent, can be extracted or mined and sold for profit. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum , natural gas , or even water . Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, and final reclamation or restoration of
1404-622: A similar meaning in modern Norwegian. Old English tūn became a common place-name suffix in England and southeastern Scotland during the Anglo-Saxon settlement period. In Old English and Early and Middle Scots , the words ton , toun , etc. could refer to diverse kinds of settlements from agricultural estates and holdings, partly picking up the Norse sense (as in the Scots word fermtoun ) at one end of
1512-488: A small city or large village; and occasionally even hamlets ). Sometimes, the word town is short for township . In general, today towns can be differentiated from townships, villages, or hamlets on the basis of their economic character, in that most of a town's population will tend to derive their living from manufacturing industry, commerce , and public services rather than primary sector industries such as agriculture or related activities. A place's population size
1620-533: A social and technical infrastructure, as well as a population of no fewer than 3500 people. For resort settlements the requirements are lower with the population needing to be no fewer than 1000 people but infrastructure requirements remain. The legal definition of a town in Canada varies by province or territory , as each has jurisdiction over defining and legislating towns, cities and other types of municipal organization within its own boundaries. The province of Quebec
1728-408: A strong inducement to extract these metals or to lease the deposits and collect royalties from mine operators. English, German , and Dutch capital combined to finance extraction and refining . Hundreds of German technicians and skilled workers were brought over; in 1642 a colony of 4,000 foreigners was mining and smelting copper at Keswick in the northwestern mountains. Use of water power in
1836-408: A town such as Parun , the capital of Nuristan Province , whose population is less 20,000 people. In Albania and Kosovo qytezë means 'town', which is very similar to the word for city ( qytet ), although there is no official use of the term for any settlement. In Albanian qytezë means 'small city' or 'new city', while in ancient times it referred to a small residential center within
1944-563: A town-like residential community between Gemeinde and Stadt with special importance to its outer conurbation area. Historically those had Marktrecht (market right) but not full town privileges; see Market town . The legal denomination of a specific settlement may differ from its common designation (e.g. Samtgemeinde – a legal term in Lower Saxony for a group of villages [ Dorf , pl. Dörfer ] with common local government created by combining municipalities [ Gemeinde , pl. Gemeinden ]). In ordinary speech, Greeks use
2052-690: Is Stadt , as it is the case in many other languages that do not differentiate between these concepts. The word for a 'village', as a smaller settlement, is Dorf . However, the International Statistics Conference of 1887 defined different sizes of Stadt , based on their population size, as follows: Landstadt ('country town'; under 5,000), Kleinstadt ('small town'; 5,000 to 20,000), Mittelstadt ('middle town'; between 20,000 and 100,000) and Großstadt ("large town"; 100,000 to 1,000,000). The term Großstadt may be translated as 'city'. In addition, Germans may speak of
2160-635: Is ammonium nitrate . Between 1870 and 1920, in Queensland Australia, an increase in mining accidents lead to more safety measures surrounding the use of explosives for mining. In the United States of America, between 1990 and 1999, about 22.3 billion kilograms of explosives were used in mining quarrying and other industries; Moreover " coal mining used 66.4%, nonmetal mining and quarrying 13.5%, metal mining 10.4%, construction 7.1%, and all other users 2.6%". Artisanal and small-scale mining (ASM)
2268-467: Is a de facto statutory city. All the Czech municipalities with more than 40,000 inhabitants are cities. Town and market town are above all ceremonious honorary degrees, referring to population, history and regional significance of a municipality. As the statistics of Czech municipalities shows, towns usually have between 1,000 and 35,000 inhabitants, with median around 4,000 and average around 6,500. Nowadays
SECTION 20
#17329314817982376-811: Is a blanket term for a type of subsistence mining involving a miner who may or may not be officially employed by a mining company but works independently, mining minerals using their own resources, usually by hand. While there is no completely coherent definition for ASM, artisanal mining generally includes miners who are not officially employed by a mining company and use their own resources to mine. As such, they are part of an informal economy . ASM also includes, in small-scale mining, enterprises or individuals that employ workers for mining, but who generally still use similar manually-intensive methods as artisanal miners (such as working with hand tools). In addition, ASM can be characterized as distinct from large-scale mining (LSM) by less efficient extraction of pure minerals from
2484-422: Is commonly referred to as a city or as a town, no distinction and no objective legal criteria exist to make such a distinction under law. Ontario allows municipalities to select whichever administrative term they like with no legal distinction existing between towns, townships, cities, and villages. Instead all municipalities, with the exception of Toronto and Ottawa, fall into one of three legal categories under
2592-520: Is difficult to call the remaining provincial capitals "large towns" as, in general, they are less developed and have shrinking population, some with as few as 30,000 inhabitants. In Bulgaria the Council of Ministers defines what constitutes a settlement, while the President of Bulgaria grants each settlement its title. In 2005 the requirement that villages that wish to classify themselves as town must have
2700-476: Is done by removing surface vegetation, dirt, and bedrock to reach buried ore deposits. Techniques of surface mining include: open-pit mining , which is the recovery of materials from an open pit in the ground; quarrying , identical to open-pit mining except that it refers to sand, stone and clay; strip mining , which consists of stripping surface layers off to reveal ore underneath; and mountaintop removal , commonly associated with coal mining, which involves taking
2808-613: Is mining upward, creating a sloping underground room, long wall mining , which is grinding a long ore surface underground, and room and pillar mining, which is removing ore from rooms while leaving pillars in place to support the roof of the room. Room and pillar mining often leads to retreat mining , in which supporting pillars are removed as miners retreat, allowing the room to cave in, thereby loosening more ore. Additional sub-surface mining methods include hard rock mining , bore hole mining, drift and fill mining, long hole slope mining, sub level caving, and block caving . Heavy machinery
2916-484: Is much more common, and produces, for example, 85% of minerals (excluding petroleum and natural gas) in the United States, including 98% of metallic ores. Targets are divided into two general categories of materials: placer deposits , consisting of valuable minerals contained within river gravels, beach sands, and other unconsolidated materials ; and lode deposits , where valuable minerals are found in veins, in layers, or in mineral grains generally distributed throughout
3024-550: Is not a reliable determinant of urban character. In many areas of the world, e.g. in India at least until recent times, a large village might contain several times as many people as a small town. In the United Kingdom, there are historical cities that are far smaller than the larger towns. The modern phenomenon of extensive suburban growth, satellite urban development, and migration of city dwellers to villages has further complicated
3132-413: Is not of immediate interest to the miner. The total movement of ore and waste constitutes the mining process. Often more waste than ore is mined during the life of a mine, depending on the nature and location of the ore body. Waste removal and placement is a major cost to the mining operator, so a detailed characterization of the waste material forms an essential part of the geological exploration program for
3240-420: Is partitioned into 2098 municipalities ( German : Gemeinden ) of fundamentally equal rank. Larger municipalities are designated as market towns ( German : Marktgemeinden ) or cities ( Städte ), but these distinctions are purely symbolic and do not confer additional legal responsibilities. There is a number of smaller communities that are labelled cities because they used to be regional population centers in
3348-584: Is recovered, reclamation can begin, to make the land used by the mine suitable for future use. Technical and economic challenges notwithstanding, successful mine development must also address human factors. Working conditions are paramount to success, especially with regard to exposures to dusts, radiation, noise, explosives hazards, and vibration, as well as illumination standards. Mining today increasingly must address environmental and community impacts, including psychological and sociological dimensions. Thus, mining educator Frank T. M. White (1909–1971), broadened

3456-634: Is the largest producer of diamonds in Africa, with an estimated 12 million carats in 2019. Other types of mining reserves in Africa include cobalt , bauxite , iron ore , coal, and copper . Gold and coal mining started in Australia and New Zealand in the 19th century. Nickel has become important in the economy of New Caledonia . In Fiji , in 1934, the Emperor Gold Mining Company Ltd. established operations at Vatukoula , followed in 1935 by
3564-423: Is to conduct a feasibility study to evaluate the financial viability, the technical and financial risks, and the robustness of the project. This is when the mining company makes the decision whether to develop the mine or to walk away from the project. This includes mine planning to evaluate the economically recoverable portion of the deposit, the metallurgy and ore recoverability, marketability and payability of
3672-464: Is unique in that it makes no distinction under law between towns and cities. There is no intermediate level in French between village and ville ( municipality is an administrative term usually applied to a legal, not geographical entity), so both are combined under the single legal status of ville . While an informal preference may exist among English speakers as to whether any individual ville
3780-419: Is used in mining to explore and develop sites, to remove and stockpile overburden, to break and remove rocks of various hardness and toughness, to process the ore, and to carry out reclamation projects after the mine is closed. Bulldozers, drills, explosives and trucks are all necessary for excavating the land. In the case of placer mining , unconsolidated gravel, or alluvium , is fed into machinery consisting of
3888-488: Is used, while the Danish equivalent of English city is storby (meaning 'large town'). For formal purposes, urban areas having at least 200 inhabitants are considered by . Historically some towns held various privileges, the most important of which was the right to hold market. They were administered separately from the rural areas in both fiscal, military and legal matters. Such towns are known as købstad (roughly
3996-513: The Greek author Diodorus Siculus , who mentions fire-setting as one method used to break down the hard rock holding the gold . One of the complexes is shown in one of the earliest known mining maps. The miners crushed the ore and ground it to a fine powder before washing the powder for the gold dust known as the dry and wet attachment processes. Mining in Europe has a very long history. Examples include
4104-507: The argentiferous galena in the mines of Cartagena ( Cartago Nova ), Linares ( Castulo ), Plasenzuela and Azuaga , among many others. Spain was one of the most important mining regions, but all regions of the Roman Empire were exploited. In Great Britain the natives had mined minerals for millennia , but after the Roman conquest , the scale of the operations increased dramatically, as
4212-806: The greenstone of the Langdale axe industry based in the English Lake District . The oldest-known mine on archaeological record is the Ngwenya Mine in Eswatini (Swaziland) , which radiocarbon dating shows to be about 43,000 years old. At this site Paleolithic humans mined hematite to make the red pigment ochre . Mines of a similar age in Hungary are believed to be sites where Neanderthals may have mined flint for weapons and tools. Ancient Egyptians mined malachite at Maadi . At first, Egyptians used
4320-484: The 1950s, to accommodate exponential population increase. The first new towns included Tsuen Wan and Kwun Tong . In the late 1960s and the 1970s, another stage of new town developments was launched. Nine new towns have been developed so far. Land use is carefully planned and development provides plenty of room for public housing projects. Rail transport is usually available at a later stage. The first towns are Sha Tin , Tsuen Wan , Tuen Mun and Tseung Kwan O . Tuen Mun
4428-505: The 21st century begins, a globalized mining industry of large multinational corporations has arisen. Peak minerals and environmental impacts have also become a concern. Different elements, particularly rare-earth minerals , have begun to increase in demand as a result of new technologies. In 2023, 8.5 billion metric tons of coal were extracted from the Earth's crust. However, as the global economy transitions away from fossil fuels and toward

The former municipalities survive as administrative subdivisions ( δημοτικά διαμερίσματα , δημοτικές ενότητες ). Cyprus, including the Turkish-occupied areas, is also divided into 39 δήμοι (in principle, with at least 5,000 inhabitants, though there are exceptions) and 576 κοινότητες . Hong Kong started developing new towns in

Gold was often traded to Mediterranean economies that demanded gold and could supply salt , even though much of Africa was abundant with salt due to the mines and resources in the Sahara desert . The trading of gold for salt was mostly used to promote trade between the different economies. Since the Great Trek in the 19th century, after, gold and diamond mining in Southern Africa has had major political and economic impacts. The Democratic Republic of Congo

These developments ushered in a “mining boom”, with gold production rising more than a hundred-fold, from 931.4 oz in 1934 to 107,788.5 oz in 1939, an order of magnitude then comparable to the combined output of New Zealand and Australia's eastern states. During prehistoric times, early Americans mined large amounts of copper along Lake Superior 's Keweenaw Peninsula and in nearby Isle Royale ; metallic copper
4968-647: The Minister of Internal Affairs selects candidates from a committee-screened list of applicants, whom the President of Republic usually affirms by issuing a bill of town's rank to them. Since being a town carries extra fiscal support from the government, many relatively small villages try to win the status of városi rang ('town rank') nowadays. Before the fall of communism in 1990, Hungarian villages with fewer than 10,000 residents were not allowed to become towns. Recently some settlements as small as 2,500 souls have received
5076-504: The Municipalities Act: Single-tier (I.e. towns that are located within a region or county but that are considered separate for municipal purposes such as Hamilton ), lower-tier (i.e. municipalities that are part of a region or county such as St. Catharines ), or upper-tier (i.e. regional municipalities such as Niagara ). Accordingly, many larger municipalities continue to use the title of town due to it better reflecting
5184-715: The National Statistics Institute (INE) as an urban entity with a population from 2001 to 5000 or an area with a population from 1001 to 2000 and an established economic activity. In Czechia , a municipality can obtain the title of a city ( Czech : statutární město ), town ( Czech : město ) or market town ( Czech : městys ). The title is granted by law. Statutory cities (in English usually called just "cities"), which are defined by law no. 128/2000 Coll., can define their own self-governing municipal districts. There are 26 such cities, in addition to Prague , which
5292-477: The Romans needed Britannia 's resources, especially gold , silver , tin , and lead . Roman techniques were not limited to surface mining. They followed the ore veins underground once opencast mining was no longer feasible. At Dolaucothi they stoped out the veins and drove adits through bare rock to drain the stopes. The same adits were also used to ventilate the workings, especially important when fire-setting
5400-539: The Spanish to pulverize ore after being mined. This device was powered by animals and used the same principles used for grain threshing . Much of the knowledge of medieval mining techniques comes from books such as Biringuccio 's De la pirotechnia and probably most importantly from Georg Agricola 's De re metallica (1556). These books detail many different mining methods used in German and Saxon mines. A prime issue in medieval mines, which Agricola explains in detail,

Other minerals mined in Egypt from the Old Kingdom (2649-2134 BC) until the Roman Period (30 BC-AD 395) including granite , sandstone , limestone , basalt , travertine , gneiss , galena , and amethyst . Mining in Egypt occurred in the earliest dynasties. The gold mines of Nubia were among the largest and most extensive of any in Ancient Egypt. These mines are described by

#17329314817985616-412: The appurtenances of local government (e.g. a police force). In the United States these are referred to as "incorporated towns". In other cases the town lacks its own governance and is said to be "unincorporated". The existence of an unincorporated town may be legally set out by other means, e.g. zoning districts. In the case of some planned communities , the town exists legally in the form of covenants on
5724-624: The beginning of civilization, people have used stone , clay and, later, metals found close to the Earth's surface. These were used to make early tools and weapons; for example, high quality flint found in northern France , southern England and Poland was used to create flint tools . Flint mines have been found in chalk areas where seams of the stone were followed underground by shafts and galleries. The mines at Grimes Graves and Krzemionki are especially famous, and like most other flint mines, are Neolithic in origin (c. 4000–3000 BC). Other hard rocks mined or collected for axes included
5832-469: The beginning of the root word (e.g. nagyváros ) have been normalized to differentiate between cities and towns (towns being smaller, therefore bearing the name kisváros .) In Hungary, a village can gain the status of város ('town'), if it meets a set of diverse conditions for quality of life and development of certain public services and utilities (e.g. having a local secondary school or installing full-area sewage collection pipe network). Every year

Later, between 2613 and 2494 BC, large building projects required expeditions abroad to the area of Wadi Maghareh in order to secure minerals and other resources not available in Egypt itself. Quarries for turquoise and copper were also found at Wadi Hammamat , Tura , Aswan and various other Nubian sites on the Sinai Peninsula and at Timna . Quarries for gypsum were found at
6048-399: The character of the municipality. For example, Oakville (2021 Population: 213,759) is the largest municipality to use the title of town to reflect its largely suburban character while other municipalities such as Richmond Hill (2021 Population: 202,022) have opted to change their status from "town" to "city" to encourage investment. In Chile , towns (Spanish: pueblos ) are defined by
6156-410: The consolidation of large estates during the Roman Empire , the town became the center of large farms. A distinction was created between rustic and urban settlements: In Afghanistan , a city and a town are both referred to as shār ( Dari : شهر ; Pashto : ښار ). The capital of each of its 34 provinces may include a major city such as Kabul whose population is over five million people or
6264-417: The cutter-head is progressively launched further into the coal seam. High wall mining can produce thousands of tons of coal in contour-strip operations with narrow benches, previously mined areas, trench mine applications and steep-dip seams. Sub-surface mining consists of digging tunnels or shafts into the earth to reach buried ore deposits. Ore, for processing, and waste rock, for disposal, are brought to
6372-414: The definition of towns, creating communities urban in their economic and cultural characteristics but lacking other characteristics of urban localities. Some forms of non-rural settlement, such as temporary mining locations, may be clearly non-rural, but have at best a questionable claim to be called a town. Towns often exist as distinct governmental units, with legally defined borders and some or all of
6480-609: The distant past. The city of Rattenberg for example has about 400 inhabitants. The city of Hardegg has about 1200 inhabitants. There are no unincorporated areas. Of the 201 cities in Austria, 15 are statutory cities ( Statutarstädte ). A statutory city is a city that is vested, in addition to its purview as a municipality, with the duties of a district administrative authority . The status does not come with any additional autonomy: district administrative authorities are essentially just service centers that citizens use to interact with

#17329314817986696-698: The focus to the “total environment of mining”, including reference to community development around mining, and how mining is portrayed to an urban society, which depends on the industry, although seemingly unaware of this dependency. He stated, “[I]n the past, mining engineers have not been called upon to study the psychological, sociological and personal problems of their own industry – aspects that nowadays are assuming tremendous importance. The mining engineer must rapidly expand his knowledge and his influence into these newer fields.” Mining techniques can be divided into two common excavation types: surface mining and sub-surface (underground) mining . Today, surface mining
6804-541: The following criteria: Mining Mining is the extraction of valuable geological materials and minerals from the surface of the Earth . Mining is required to obtain most materials that cannot be grown through agricultural processes , or feasibly created artificially in a laboratory or factory. Ores recovered by mining include metals , coal , oil shale , gemstones , limestone , chalk , dimension stone , rock salt , potash , gravel , and clay . The ore must be
6912-481: The form of water mills was extensive. The water mills were employed in crushing ore, raising ore from shafts, and ventilating galleries by powering giant bellows . Black powder was first used in mining in Selmecbánya , Kingdom of Hungary (now Banská Štiavnica , Slovakia) in 1627. Black powder allowed blasting of rock and earth to loosen and reveal ore veins. Blasting was much faster than fire-setting and allowed
7020-400: The growing importance of sustainable metal extraction practices. The process of mining from discovery of an ore body through extraction of minerals and finally to returning the land to its natural state consists of several distinct steps. The first is discovery of the ore body, which is carried out through prospecting or exploration to find and then define the extent, location and value of
7128-421: The historical importance, the existence of central functions (education, retail etc.) and the population density of an urban place might also be taken as characteristics of a Stadt . The modern local government organisation is subject to the laws of each state and refers to a Gemeinde ( municipality ), regardless of its historic title. While most Gemeinden form part of a Landkreis ( district ) on
7236-421: The land after the mine is closed. Mining materials are often obtained from ore bodies, lodes , veins , seams , reefs , or placer deposits . The exploitation of these deposits for raw materials is dependent on investment, labor, energy, refining, and transportation cost. Mining operations can create a negative environmental impact, both during the mining activity and after the mine has closed. Hence, most of

In the early colonial history of the Americas, "native gold and silver was quickly expropriated and sent back to Spain in fleets of gold- and silver-laden galleons", the gold and silver originating mostly from mines in Central and South America. Turquoise dated at 700 AD
7452-753: The mid-19th century, mining for minerals and precious metals, along with ranching , became a driving factor in the U.S. Westward Expansion to the Pacific coast. With the exploration of the West, mining camps sprang up and "expressed a distinctive spirit, an enduring legacy to the new nation"; Gold Rushers would experience the same problems as the Land Rushers of the transient West that preceded them. Aided by railroads, many people traveled West for work opportunities in mining. Western cities such as Denver and Sacramento originated as mining towns. When new areas were explored, it
7560-442: The mid-sixteenth century. On the continent, mineral deposits belonged to the crown, and this regalian right was stoutly maintained. But in England, royal mining rights were restricted to gold and silver (of which England had virtually no deposits) by a judicial decision of 1568 and a law in 1688. England had iron , zinc , copper , lead , and tin ores. Landlords who owned the base metals and coal under their estates then had
7668-432: The minehead, where the water was stored in large reservoirs and tanks. When a full tank was opened, the flood of water sluiced away the overburden to expose the bedrock underneath and any gold-bearing veins. The rock was then worked by fire-setting to heat the rock, which would be quenched with a stream of water. The resulting thermal shock cracked the rock, enabling it to be removed by further streams of water from
7776-431: The mining of previously impenetrable metals and ores. In 1762, one of the world's first mining academies was established in the same town there. The widespread adoption of agricultural innovations such as the iron plowshare , as well as the growing use of metal as a building material, was also a driving force in the tremendous growth of the iron industry during this period. Inventions like the arrastra were often used by
7884-542: The name of their respective seats, and if they were not municipal seats, they would have the category of village. Bulgarians do not, in general, differentiate between 'city' and 'town'. However, in everyday language and media the terms "large towns" and "small towns" are in use. "Large towns" usually refers to Sofia , Plovdiv , Varna and Burgas , which have population over 200,000. Ruse and Stara Zagora are often included as well due to presence of relatively developed infrastructure and population over 100,000 threshold. It
7992-418: The national government, for example to apply for driver licenses or passports. The national government generally uses the provinces to run these points of contact on its behalf; in the case of statutory cities, the municipality gets to step up. In Brazil, since 1938, it was defined that the seat of the municipalities would pass to the category of city and give it the name and the districts would be designated by
8100-405: The ore body. This leads to a mathematical resource estimation to estimate the size and grade of the deposit. This estimation is used to conduct a pre-feasibility study to determine the theoretical economics of the ore deposit. This identifies, early on, whether further investment in estimation and engineering studies is warranted and identifies key risks and areas for further work. The next step
8208-462: The ore concentrates, engineering concerns, milling and infrastructure costs, finance and equity requirements, and an analysis of the proposed mine from the initial excavation all the way through to reclamation. The proportion of a deposit that is economically recoverable is dependent on the enrichment factor of the ore in the area. To gain access to the mineral deposit within an area it is often necessary to mine through or remove waste material which
8316-442: The ore, lower wages, decreased occupational safety, benefits, and health standards for miners, and a lack of environmental protection measures. Artisanal miners often undertake the activity of mining seasonally. For example, crops are planted in the rainy season , and mining is pursued in the dry season . However, they also frequently travel to mining areas and work year-round. There are four broad types of ASM: Surface mining
8424-556: The overhead tanks. The Roman miners used similar methods to work cassiterite deposits in Cornwall and lead ore in the Pennines . Sluicing methods were developed by the Romans in Spain in 25 AD to exploit large alluvial gold deposits, the largest site being at Las Medulas , where seven long aqueducts tapped local rivers and sluiced the deposits. The Romans also exploited the silver present in
8532-476: The properties within the town. The United States Census identifies many census-designated places (CDPs) by the names of unincorporated towns which lie within them; however, those CDPs typically include rural and suburban areas and even surrounding villages and other towns. The distinction between a town and a city similarly depends on the approach: a city may strictly be an administrative entity which has been granted that designation by law, but in informal usage,
8640-417: The rank of town (e.g. Visegrád, Zalakaros or Gönc) and meeting the conditions of development is often disregarded to quickly elevate larger villages into towns. As of middle 2013, there are 346 towns in Hungary, encompassing some 69% of the entire population. Towns of more than 50,000 people are able to gain the status of megyei jogú város (town with the rights of a county ), which allows them to maintain
8748-431: The remaining part of a coal seam previously exploited by other surface-mining techniques has too much overburden to be removed but can still be profitably exploited from the side of the artificial cliff made by previous mining. A typical cycle alternates sumping, which undercuts the seam, and shearing, which raises and lowers the cutter-head boom to cut the entire height of the coal seam. As the coal recovery cycle continues,
8856-557: The same meaning as borough albeit deriving from a different etymology) and they retain the exclusive right to the title even after the last vestiges of their privileges vanished through the reform of the local administration carried through in 1970. In Estonia , there is no distinction between a town and a city as the word linn is used for both bigger and smaller settlements, which are bigger than villages and boroughs. There are 30 municipal towns ( omavalitsuslik linn ) in Estonia and
8964-404: The scale, to fortified municipalities. Other common Anglo-Saxon suffixes included ham 'home', stede 'stead', and burh 'bury, borough, burgh'. In toponymic terminology, names of individual towns and cities are called astyonyms or astionyms (from Ancient Greek ἄστυ 'town, city', and ὄνομα 'name'). In some cases, town is an alternative name for "city" or "village" (especially
9072-446: The shafts could no longer be pumped dry with the available technology. Although an increased use of banknotes , credit and copper coins during this period did decrease the value of, and dependence on, precious metals , gold and silver still remained vital to the story of medieval mining. Due to differences in the social structure of society, the increasing extraction of mineral deposits spread from central Europe to England in
9180-558: The silver mines of Laurium , which helped support the Greek city state of Athens . Although they had over 20,000 slaves working them, their technology was essentially identical to their Bronze Age predecessors. At other mines, such as on the island of Thassos , marble was quarried by the Parians after they arrived in the 7th century BC. The marble was shipped away and was later found by archaeologists to have been used in buildings including
9288-430: The smallest level of local authorities are all called communes . They can have anywhere from a handful to millions of inhabitants, and France has 36,000 of them. The French term for town is bourg but French laws generally do not distinguish between towns and cities which are all commonly called villes . However, some laws do treat these authorities differently based on the population and different rules apply to
9396-474: The surface through the tunnels and shafts. Sub-surface mining can be classified by the type of access shafts used, and the extraction method or the technique used to reach the mineral deposit. Drift mining uses horizontal access tunnels, slope mining uses diagonally sloping access shafts, and shaft mining uses vertical access shafts. Mining in hard and soft rock formations requires different techniques. Other methods include shrinkage stope mining , which
9504-421: The term is also used to denote an urban locality of a particular size or importance: whereas a medieval city may have possessed as few as 10,000 inhabitants, today some consider an urban place of fewer than 100,000 as a town, even though there are many officially designated cities that are much smaller than that. 193 countries have been involved in a common effort to agree on a common statistical definition of
9612-607: The three big cities Paris , Lyon and Marseille . For historical reasons, six communes in the Meuse département exist as independent administrative entities despite having no inhabitants at all. For statistical purposes, the national statistical institute ( INSEE ) operates a distinction between urban areas with fewer than 2,000 inhabitants and bigger communes, the latter being called villes . Smaller settlements are usually called villages . Germans do not, in general, differentiate between 'city' and 'town'. The German word for both
9720-455: The three categories: cities, towns and rural areas. Australian geographer Thomas Griffith Taylor proposed a classification of towns based on their age and pattern of land use . He identified five types of towns: Through different periods of recorded history, many towns have grown into sizeable settlements, with the development of properties, centres of culture, and specialized economies. Çatalhöyük , currently an archaeological site,
9828-590: The tomb of Amphipolis. Philip II of Macedon , the father of Alexander the Great , captured the gold mines of Mount Pangeo in 357 BC to fund his military campaigns. He also captured gold mines in Thrace for minting coinage, eventually producing 26 tons per year. However, it was the Romans who developed large-scale mining methods, especially the use of large volumes of water brought to the minehead by numerous aqueducts . The water
9936-448: The top of a mountain off to reach ore deposits at depth. Most placer deposits, because they are shallowly buried, are mined by surface methods. Finally, landfill mining involves sites where landfills are excavated and processed. Landfill mining has been thought of as a long-term solution to methane emissions and local pollution. High wall mining, which evolved from auger mining, is another form of surface mining. In high wall mining,
10044-614: The top slats. Many examples of such devices have been found in old Roman mines and some examples are now preserved in the British Museum and the National Museum of Wales . Mining as an industry underwent dramatic changes in medieval Europe . The mining industry in the early Middle Ages was mainly focused on the extraction of copper and iron . Other precious metals were also used, mainly for gilding or coinage. Initially, many metals were obtained through open-pit mining , and ore
10152-675: The walls of a castle. In Australia, most rural and regional centres of population can be called towns; many small towns have populations of less than 200. The smallest may be described as townships. In addition, some local government entities are officially styled as towns in Queensland , South Australia , Western Australia and the Northern Territory , and formerly also (till the 1990s) in Victoria . The Austrian legal system does not distinguish between villages, towns, and cities. The country
10260-617: The word χωριό ('village') to refer to smaller settlements and the word πόλη or πολιτεία ('city') to refer to larger ones. Careful speakers may also use the word κωμόπολη to refer to towns with a population of 2,000–9,999. In Greek administrative law there used to be a distinction between δήμοι , i.e. municipalities with more than 10,000 inhabitants or considered important for some other geographical (county seats), historical or ecclesiastical (bishops' seats) reason, and κοινότητες, referring to smaller self-governing units, mostly villages. A sweeping reform, carried out in two stages early in
10368-461: The world's gold, followed by the establishment of large mines such as the Mount Morgan Mine , which ran for nearly a hundred years, Broken Hill ore deposit (one of the largest zinc-lead ore deposits), and the iron ore mines at Iron Knob . After declines in production, another boom in mining occurred in the 1960s. In the early 21st century, Australia remains a major world mineral producer. As
10476-652: The world's nations have passed regulations to decrease the impact; however, the outsized role of mining in generating business for often rural, remote or economically depressed communities means that governments often fail to fully enforce such regulations. Work safety has long been a concern as well, and where enforced, modern practices have significantly improved safety in mines. Unregulated, poorly regulated or illegal mining , especially in developing economies , frequently contributes to local human rights violations and environmental conflicts . Mining can also perpetuate political instability through resource conflicts . Since
10584-468: The world, which was increasingly demanding copper for electrical and household goods. Canada's mining industry grew more slowly than did the United States due to limitations in transportation, capital, and U.S. competition; Ontario was the major producer of the early 20th century with nickel, copper, and gold. Meanwhile, Australia experienced the Australian gold rushes and by the 1850s was producing 40% of
10692-498: Was considered to be the oldest inhabited town, or proto-city , that existed from around 7500 BC. Inscribed as a World Heritage Site , it remains a depopulated town with a complex of ruins. In Roman times , a villa was a rural settlement formed by a main residential building and another series of secondary buildings. It constituted the center from which an agricultural holding was administered. Subsequently, it lost its agricultural functions and reduced its activity to residential. With
10800-534: Was intended to be self-reliant, but was not successful and turned into a bedroom community like the other new towns. More recent developments are Tin Shui Wai and North Lantau (Tung Chung-Tai Ho) . In Hungary there is no official distinction between a city and a town (the word for both in Hungarian is város ). Nevertheless, the expressions formed by adding the adjectives kis ('small') and nagy ('large') to
10908-612: Was mined in pre-Columbian America; in the Cerillos Mining District in New Mexico , an estimate of "about 15,000 tons of rock had been removed from Mt. Chalchihuitl using stone tools before 1700." In 1727 Louis Denys (Denis) (1675–1741), sieur de La Ronde – brother of Simon-Pierre Denys de Bonaventure and the son-in-law of René Chartier – took command of Fort La Pointe at Chequamegon Bay ; where natives informed him of an island of copper. La Ronde obtained permission from
11016-576: Was primarily extracted from shallow depths, rather than through deep mine shafts. Around the 14th century , the growing use of weapons , armour , stirrups , and horseshoes greatly increased the demand for iron. Medieval knights , for example, were often laden with up to 100 pounds (45 kg) of plate or chain link armour in addition to swords , lances and other weapons. The overwhelming dependency on iron for military purposes spurred iron production and extraction processes. The silver crisis of 1465 occurred when all mines had reached depths at which
11124-406: Was still present near the surface in colonial times. Indigenous peoples used Lake Superior copper from at least 5,000 years ago; copper tools, arrowheads, and other artifacts that were part of an extensive native trade-network have been discovered. In addition, obsidian , flint , and other minerals were mined, worked, and traded. Early French explorers who encountered the sites made no use of
11232-405: Was that of a fortress or an enclosure. Cognates of town in many modern Germanic languages designate a fence or a hedge. In English and Dutch, the meaning of the word took on the sense of the space which these fences enclosed, and through which a track must run. In England, a town was a small community that could not afford or was not allowed to build walls or other larger fortifications, and built
11340-411: Was the removal of water from mining shafts. As miners dug deeper to access new veins, flooding became a very real obstacle. The mining industry became dramatically more efficient and prosperous with the invention of mechanically- and animal-driven pumps. Iron metallurgy in Africa dates back over four thousand years. Gold became an important commodity for Africa during the trans-Saharan gold trade from
11448-403: Was used for a variety of purposes, including removing overburden and rock debris, called hydraulic mining , as well as washing comminuted , or crushed, ores and driving simple machinery. The Romans used hydraulic mining methods on a large scale to prospect for the veins of ore, especially using a now-obsolete form of mining known as hushing . They built numerous aqueducts to supply water to
11556-461: Was used. At other parts of the site, they penetrated the water table and dewatered the mines using several kinds of machines, especially reverse overshot water-wheels . These were used extensively in the copper mines at Rio Tinto in Spain, where one sequence comprised 16 such wheels arranged in pairs, and lifting water about 24 metres (79 ft). They were worked as treadmills with miners standing on
11664-539: Was usually the gold ( placer and then lode ) and then silver that were taken into possession and extracted first. Other metals would often wait for railroads or canals, as coarse gold dust and nuggets do not require smelting and are easy to identify and transport. In the early 20th century, the gold and silver rush to the western United States also stimulated mining for coal as well as base metals such as copper, lead, and iron. Areas in modern Montana, Utah, Arizona, and later Alaska became predominant suppliers of copper to
