| 摘 要： | 为制定某钨矿资源合理的开发利用方案，对该矿有代表性矿样进行了工艺矿物学研究。结果表明：矿石中主要有价元素为钨、钼、铜，对应的主要有用矿物为白钨矿、辉钼矿、黄铜矿；矿石中有用矿物嵌布关系复杂，嵌布粒度较细，白钨矿属于细粒较均匀嵌布类型，而黄铜矿和辉钼矿则属于微细粒不均匀嵌布类型；白钨矿WO3品位高达74.76%，95.30%的钨赋存在白钨矿中，辉钼矿Mo品位达57.84%，白钨矿Mo品位为2.83%，58.25%的钼赋存在辉钼矿中，33.20%的钼赋存在白钨矿中，黄铜矿Cu品位达31.24%，87.92%的铜赋存在黄铜矿中；白钨矿较易解离，辉钼矿次之，黄铜矿较难单体解离；矿石在磨矿细度为-0.074 mm占65.81%时白钨矿的单体解离度达97.48%、黄铜矿为89.20%、辉钼矿为91.67%。

| Abstract: | Process mineralogy research on representative samples of the tungsten ore was carried out in order to explore a reasonable exploitation and utilization scheme.The result indicated that the valuable elements of the ore include wolfram，molybdenum and copper and their corresponding valuable minerals are scheelite，molybdenite and chalcopyrite respectively.The valuable minerals are complexly and finely disseminated with each other.The scheelite is finely and evenly disseminated，while chalcopyrite and molybdenite are micro-finely and unevenly disseminated.The grade of WO3 in scheelite reached 74.76% and 95.30% of wolfram exist in scheelite.The grade of molybdenum in molybdenite and scheelite was 57.84% and 2.83% respectively.And 58.25% of molybdenum exists in molybdenite and 33.20% of molybdenum existed in scheelite.The copper grade in chalcopyrite is 31.24% and 87.92% of copper exists in chalcopyrite.The scheelite is easier to be liberated，followed by molybdenite，while chalcopyrite is the hardest.The liberation degree of scheelite，chalcopyrite and molybdenite were 97.48%，89.20 and 91.67% respectively at the grinding fineness of 65.81% passing -0.074 mm. |
