The Johnson Lake Mine is a former tungsten mine located within the boundaries of Great Basin National Park in eastern Nevada.Located on the east slope of the southern Snake Range at an elevation above 10,000 ft (3,000 m), the 100 acres (40 ha) historic district was listed on the National Register of Historic Places in 1995.
Wah Chang is Cantonese for "fortunate enterprise" [6] or "great development". [7] This expanded as an international tungsten ore and concentrate trading company. [2] In 1946, the company built a plant in Union City, New Jersey. In the 1950s, it was also operating tungsten mines in Calento, Nevada, and near Bishop, California. [5]
The lithium mine is proposed to be a carbon-neutral operation, generating electric power from a sulfuric acid plant built on-site to leach lithium from the extracted ore. [43] The Final Environmental Impact Statement (FEIS) for the mine estimated Phase 2 emissions at an equivalent of 132,000 tons per year of CO2 [ 44 ] with an additional 20,000 ...
Mining of tungsten ore began in 1938. However, due to the Korean War, prices of tungsten rose steeply. Leading to an increase of unlicensed mining in the area. These mining activities eventually stopped in 1967, abandoning operations of all the mining facilities. [2] Other ores, for instance Lead, Zinc and Copper, were found in Lead Mine Pass ...
Tungsten ore is a rock from which the element tungsten can be economically extracted. The ore minerals of tungsten include wolframite, scheelite, and ferberite. Tungsten is used for making many alloys. Tungsten ore deposits are predominantly magmatic or hydrothermal in origin and are associated with felsic igneous intrusions. [1]
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. [2]

It was Canada's longest lived continuous mining operation and produced metals worth over $20 billion in terms of 2005 metal prices. Grading was in excess of 5% Pb and 6% Zn. The ore genesis of the Sullivan ore body is summarized by the following process: Sediments were deposited in an extensional second-order sedimentary basin during extension.
