摘要
洛钼集团三道庄露天矿区为一特大矽卡岩型钼钨矿床,选矿二公司技术人员通过实验室试验和工业试验,对从钼精扫尾矿中回收铜进行了系统试验研究,解决了三道庄钼钨矿中极低品位铜综合回收的难题。通过浓缩、过滤、活化、浮选等工艺,采用一粗—四精—两扫的闭路流程,获得了品位为20%的铜精矿。研究不仅综合回收了钼钨矿中的铜资源,而且对洛钼集团各分子公司和同类型矿山有重要的借鉴意义。
Sandaozhuang open pit mine is an extra big skarn molybdenum-tungsten deposit. Recovering copper from molybdenum roughing tailings were studied experimentally and systematically through laboratory and industrial tests by technicians from the Second Mineral Processing Company,the problem of comprehensive recovery low grade copper from Sandaozhuang molybdenum-tungsten ore was solved. Through concentration,filtration,activation,flotation and the closed-circuit process of one roughing four concentration-two scavening,copper concentrate with grade of 20% was obtained. The study has significant reference value to subsidiaries of China Molybdenum Co.,Ltd and the same type mines.
