针对青海某低品位铅锌矿，利用显微镜下研究、化学分析、电子探针、扫描电镜等手段，查清了矿石的矿物组成，查明了矿石的结构构造，并进行了主要矿物工艺矿物粒度测定。研究结果表明，虽然方铅矿嵌布粒度较细，但方铅矿解理发育，且与周围矿物接触较平直，在磨矿作业中易单体解理，有利于其选矿富集，而闪锌矿由于含量低，嵌布粒度微细，选矿难度较大。

Using microscope , chemical analysis , electron microprobe and scanning electron micros-copy ( SEM) , the mineral composition and structure of a low grade lead -zinc ore were studied and determined , and the process mineral grain size was measured .The research results show that the disseminated grain size of galena was fine , but the cleavage developed well , and the contact bound-ary with the surrounding minerals were straight , which make it easy to monomer dissociate in grind-ing operation , so it was conducive to the beneficiation process .Due to the low content and fine dis-seminated grain size , the separation of sphalerite was difficult .
