The Ruashi Mine is an open-pit copper and cobalt mine operated by Metorex that is located about from Lubumbashi in Katanga Province, Democratic Republic of the Congo. The project includes a plant to concentrate the ore from the Ruashi and Etoile mines, and a modern solvent extraction electrowinning (SX-EW) processing plant.〔 As of 2008, annual capacity was estimated to be 10,000 tonnes of copper and 1,000 tonnes of Cobalt. ==Location== The Ruashi mine is located at an elevation of about above sea level. The climate is sub-tropical, with annual rainfall of about falling mostly in the October to March period. Average temperatures are between and , with no marked difference between summer and winter. The region lies in a zone that would naturally be covered by Miombo Woodland, deciduous tropical woodlands. Lying on the edge of Lubumbashi, much of the woodland has been cleared.〔 Tanganyika Concessions Ltd dug pits and trenches in the area in 1907. Union Minière du Haut Katanga (UMHK) discovered the Etoile ore body in 1911, and the Ruashi ore body in 1919. For the next half century both properties were quarried intermittently for their high-grade copper ore. UMHK was nationalized in 1967. Control of all copper and cobalt exploration and production was given to Gécamines, established as the state mining company.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Ruashi Mine」の詳細全文を読む スポンサード リンク
