Cantung Mine
Cantung Mine is a tungsten producer in the Nahanni area of the Northwest Territories, Canada, located northeast of Watson Lake in the Flat River Valley of the Selwyn Range close to the Yukon border. Tungsten was originally discovered in the area in 1954 by prospectors. Cantung Mine operated from 1962 to 1986, again from 2002 to 2003, and from 2005. Production was suspended from October 2009 to October 2010. The mine owner, North American Tungsten Corporation, went bankrupt in 2015 and the mine closed in October of that year. The federal government of Canada now owns the mine and has to clean up the site. As of December, 2017, the mine remained closed, with the possibility of being opened to process a nearby lithium deposit. As of February 2019, the mine is still closed; the federal and NWT governments are trying to sell it. 1962—1986 The original company that developed the mine was Canada Tungsten Mining Corporation Limited, with ''Cantung'' being a short abbreviated form o ...

Tungsten, Northwest Territories
The townsite of Tungsten (shown as Cantung on some maps) is located at Cantung Mine in the Northwest Territories. It is accessible from Watson Lake, Yukon via the Nahanni Range Road History Tungsten was built in 1961 and the tungsten mine went into operation in 1962 as a large open-pit mine in the Mackenzie Mountains. It originally consisted of several small bungalow houses. Total population of Tungsten during the 1960s was approximately 120 persons, including about 27 families. In 1968 families were housed in 28 units (single and duplex housing). Because of extremely good wages and benefits, turnover rates for the entire operation were quite low. Families benefited from the K-8 Grade school, and later a K-9 system. During the summer months, because of the open pit operation, manpower and townsite population grew to 160. In the mid-1970s, the townsite expanded to include a trailer court, three condominiums, bunkhouse trailers, and in 1982, a modern recreation complex. An 80 ...

Tungsten
Tungsten, or wolfram, is a chemical element with the symbol W and atomic number 74. Tungsten is a rare metal found naturally on Earth almost exclusively as compounds with other elements. It was identified as a new element in 1781 and first isolated as a metal in 1783. Its important ores include scheelite and wolframite, the latter lending the element its alternate name. The free element is remarkable for its robustness, especially the fact that it has the highest melting point of all known elements barring carbon (which sublimes at normal pressure), melting at . It also has the highest boiling point, at . Its density is , comparable with that of uranium and gold, and much higher (about 1.7 times) than that of lead. Polycrystalline tungsten is an intrinsically brittle and hard material (under standard conditions, when uncombined), making it difficult to work. However, pure single-crystalline tungsten is more ductile and can be cut with a hard-steel hacksaw. Tungsten occurs in many ...

Northwest Territories
The Northwest Territories (abbreviated ''NT'' or ''NWT''; french: Territoires du Nord-Ouest, formerly ''North-Western Territory'' and ''North-West Territories'' and namely shortened as ''Northwest Territory'') is a federal territory of Canada. At a land area of approximately and a 2016 census population of 41,790, it is the second-largest and the most populous of the three territories in Northern Canada.

North American Tungsten Corporation
North is one of the four compass points or cardinal directions. It is the opposite of south and is perpendicular to east and west. ''North'' is a noun, adjective, or adverb indicating direction or geography. Etymology The word ''north'' is related to the Old High German ''nord'', both descending from the Proto-Indo-European unit *''ner-'', meaning "left; below" as north is to left when facing the rising sun. Similarly, the other cardinal directions are also related to the sun's position. The Latin word ''borealis'' comes from the Greek '' boreas'' "north wind, north", which, according to Ovid, was personified as the wind-god Boreas, the father of Calais and Zetes. ''Septentrionalis'' is from ''septentriones'', "the seven plow oxen", a name of ''Ursa Major''. The Greek ἀρκτικός (''arktikós'') is named for the same constellation, and is the source of the English word ''Arctic''. Other languages have other derivations. For example, in Lezgian, ''kefer'' can mean b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Open-pit Mining
Open-pit mining, also known as open-cast or open-cut mining and in larger contexts mega-mining, is a surface mining technique of extracting rock or minerals from the earth from an open-air pit, sometimes known as a borrow. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mining. Open-pit mines are used when deposits of commercially useful ore or rocks are found near the surface. It is applied to ore or rocks found at the surface because the overburden is relatively thin or the material of interest is structurally unsuitable for tunnelling (as would be the case for cinder, sand, and gravel). In contrast, minerals that have been found underground but are difficult to retrieve due to hard rock, can be reached using a form of underground mining. To create an open-pit mine, the miners must determine the information of the ore that is underground. This is done through drilling of probe holes in the ground, then plotting ea ...
