摘　　要：研究干式铁磨和干式瓷磨对黄铁矿表面性质以及后续浮选的影响。结果表明,瓷介质磨矿的矿物浮游性较铁介质磨矿的矿物浮游性好,黄铁矿氧化形成的缺金属富硫表面和矿物晶格中的阳离子空位将大大提高黄铁矿的回收率和浮游速度。The effect of the dry-grinding on the surface properties and flotation behaviors of pyrite being ground with iron media and ceramic media is investigated.The results show that the floatability of pyrite ground with ceramic media is better than that ground with iron media,and the recovery and floatation rate are greatly improved due to sulfur-lacking while metal-exceeding surface and cation vacancy in mineral crystal lattice.
