摘要: 利用显微镜、电子探针和扫描电镜对云南个旧西凹铜多金属矿床围岩、蚀变花岗岩、矿石样品进行观察和微观分析,查明了矿床主要成矿元素铜、锡和钨等的赋存特征。研究结果表明,铜主要以黄铜矿、硫砷铜矿形式存在;锡主要以锡石、黄锡矿形式存在;钨主要以白钨矿形式存在。除可工业利用铜、锡和钨元素外,还可综合利用钼和铋元素。成

Abstract: This paper investigated the occurrence characteristics of main ore-forming elements such as Cu,Sn,W in deposit,from the observe and analysis on the wall-rocks,altered granite and ore samples in Xi'ao copper-polymetallic deposit in Gejiu,Yunnan by using optical microscopy,electron probe micro-analyzer(EPMA) and scanning electron microscopy(SEM).The results showed that copper occurs as chalcopyrite and enargite,tin occurs as cassiterite and custerite,and tungsten occurs as scheelite.Besides Cu,Sn,W used in industry,Mo,Bi can be comprehensively utilized as well.
