Twin Metals Mine
Twin Metals LLC is seeking approval to create and operate a copper sulfide mine near Ely, Minnesota, on Superior National Forest land. There has been significant opposition to the proposed mine, most notably because of its proximity to the Boundary Waters Canoe Area Wilderness, location within a watershed that drains into the BWCA, and the air, water, light and noise pollution and traffic effects of converting a forested area bordering the BWCA into a substantial industrial mining facility. Twin Metals is a subsidiary of the Chilean conglomerate Antofagasta PLC, Antofagasta, which is controlled by billionaire Andrónico Luksic Craig, Andrónico Luksic. The original lease is a 1966 lease to the International Nickel Corporation. The facility would have an underground mining area accessed by two sloping tunnels, an above-ground processing factory, and a tailings dumping area that would use the dry-storage method. Twin Metals has estimated that the mine would provide 700 jobs and creat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Copper Sulfide
Copper sulfides describe a family of chemical compounds and minerals with the formula CuxSy. Both minerals and synthetic materials comprise these compounds. Some copper sulfides are economically important ores. Prominent copper sulfide minerals include Cu2S ( chalcocite) and CuS ( covellite). In the mining industry, the minerals bornite or chalcopyrite, which consist of mixed copper-iron sulfides, are often referred to as "copper sulfides". In chemistry, a "binary copper sulfide" is any binary chemical compound of the elements copper and sulfur. Whatever their source, copper sulfides vary widely in composition with 0.5 ≤ Cu/S ≤ 2, including numerous non-stoichiometric compounds. Known copper sulfides The naturally occurring mineral binary compounds of copper and sulfur are listed below. Investigations of covellite ( CuS) indicate that there are other metastable Cu-S phases still to be fully characterised. * CuS2, villamaniniteWells A.F. (1984) ''Structural Inorganic C ...

Acid Mine Drainage
Acid mine drainage, acid and metalliferous drainage (AMD), or acid rock drainage (ARD) is the outflow of acidic water from metal mines and coal mines. Acid rock drainage occurs naturally within some environments as part of the rock weathering process but is exacerbated by large-scale earth disturbances characteristic of mining and other large construction activities, usually within rocks containing an abundance of sulfide minerals. Areas where the earth has been disturbed (e.g. construction sites or highway construction) may create acid rock drainage. In many localities, the liquid that drains from coal stocks, coal handling facilities, coal washeries, and coal waste tips can be highly acidic, and in such cases it is treated as acid rock drainage. These, combined with reduced pH, have a detrimental impact on the streams' aquatic environments. The same type of chemical reactions and processes may occur through the disturbance of acid sulfate soils formed under coastal or ...

Iron Range
The Iron Range is collectively or individually a number of elongated iron-ore mining districts around Lake Superior in the United States and Canada. Much of the ore-bearing region lies alongside the range of granite hills formed by the Giants Range batholith. These cherty iron ore deposits are Precambrian in the Vermilion Range and middle Precambrian in the Mesabi and Cuyuna ranges, all in Minnesota. The Gogebic Range in Wisconsin and the Marquette Iron Range and Menominee Range in Michigan have similar characteristics and are of similar age. Natural ores and concentrates were produced from 1848 until the mid-1950s, when taconites and jaspers were concentrated and pelletized, and started to become the major source of iron production. The mining districts are in Minnesota's Arrowhead Region. The region's far eastern area, containing the Duluth Complex along the shore of Lake Superior, and the far northern area, along the Canada–U.S. border, are not associated with iron ...
