摘　　要：为高效利用内蒙古某选厂含铜铅精矿,通过化学多元素分析、铜物相分析、光学显微镜、MLA等多种分析手段,对含铜铅精矿进行了详细的工艺矿物学研究。结果表明:含铜铅精矿中铅、铜含量分别为72.58%、0.81%,矿物组成以方铅矿为主,少量闪锌矿、黄铁矿、黄铜矿及其他矿物,方铅矿、黄铜矿的嵌布粒度主要处于0.01~0.10 mm,属细粒级嵌布范畴,方铅矿和黄铜矿的单体+富连生体占比分别为97.14%,86.23%,解离情况好,在合理的选矿工艺条件下,可有效实现铜、铅的分离与富集。In order to make efficient use of concentrate containing copper and lead from a concentrator in Inner Mongolia,the process mineralogy of concentrate containing copper and lead was studied in detail by means of chemical multi-element analysis,copper phase analysis,optical microscope,MLA and other analytical methods.The results show that the contents of lead and copper in the concentrate containing cop⁃per and lead are 72.58%and 0.81%,respectively.The mineral composition is mainly galena,with a small amount of sphalerite,pyrite,chalcopyrite and other minerals.The dissemination size of galena and chalco⁃pyrite is mainly in the range of 0.01~0.10 mm,which belongs to the category of fine-grained dissemination.The proportion of monomer+rich coenobium in galena and chalcopyrite is 97.14%and 86.23%,respective⁃ly,and the dissociation situation is good.Under the reasonable beneficiation process conditions,the separa⁃tion and enrichment of copper and lead can be effectively realized.
