Luishia mine was an open pit copper and cobalt mine in Katanga Province, Democratic Republic of the Congo. A concession to the south of the mine has recently been opened to exploitation. ==Original open pit mine== The reduced facies-type deposit of copper and cobalt was mined from 1913 to 1949 by the Union Miniere du Haut Katanga.〔(【引用サイトリンク】title=Luishia Mine, Katanga, Katanga Copper Crescent, Katanga (Shaba), Democratic Republic of Congo (Zaïre) )〕 In October 1928 the mine employed 1,466 men. That month there were two deaths, and 16.37% of the men fell ill. The mine was hit by arson and sabotage in 1938 by miners dissatisfied with their pay and working conditions. In December 1941 the miners, and those in other mines in the area, began a general strike. While the open pit mine was in operation a total of 4.1 million tonnes of ore were extracted with an average grade of 8.3% copper.〔 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「Luishia Mine」の詳細全文を読む スポンサード リンク
