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.

Abstract: 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.

Key words: copper-molybdenum mixed concentrate; process mineralogy; copper minerals; molybdenite
