摘　　要：研究了干式磨矿对闪锌矿、黄铁矿单矿物及双矿物磨矿矿浆化学性质的影响,并采用光电子能谱(XPS)考察磨矿过程中硫化矿物表面变化的情况,确定硫化矿物表面物质的存在形式。结果表明,黄铁矿经干磨以后矿物表面变化较大且有新物质FeSO_4生成。Study is made on are ground alone and figure out what is on after dry-grinding and the effect of the dry-grinding on the pulp chemistry of sphalerite and pyrite which together, furthermore, XPS is adopted to detect the surface of minerals in order to the surface. The results show that there is great difference on the surface of pyrite FeSO4 is detected on the surface.
