摘　　要：采用化学分析、显微镜下分析和MLA分析等方法对西藏某铜钼混合精矿进行了工艺矿物学研究.研究表明:该混合精矿中铜质量分数19.00%、钼质量分数0.38%,铜、钼均主要以硫化物的形式存在;混合精矿中主要矿物为黄铁矿、黄铜矿和斑铜矿,辉钼矿的质量分数为1.0%;混合精矿磨矿细度很细;辉钼矿解离程度较好,少部分辉钼矿以与黄铜矿、黄铁矿连生的形式存在.研究结果为现场铜钼分离改造提供了理论指导.The process mineralogy of a copper-molybdenum mixed concentrate in Tibet was studied by means of chemical analysis,microscopic analysis and MLA analysis.The research shows that the mixed concentrate contains 19.00%copper and 0.38%molybdenum,and both copper and molybdenum mainly exist in the form of sulfide.Pyrite,chalcopyrite and bornite are the main minerals in the mixed concentrate,with molybdenite present at a content of 1.0%.The grinding fineness of the mixed concentrate is extremely fine,and the degree of dissociation of molybdenite is excellent.Additionally,a small part of molybdenite exists in coexistence with chalcopyrite and pyrite.The research results provide theoretical guidance for on-site copper-molybdenum separation and transformation.
