摘　　要：某矿样含铜0.933%,含铅1.326%,含锌2.346%,且含有大量的黄铁矿,属较难分选的低品位多金属矿石。通过试验,推荐使用:“部分混合-优先浮选”的流程。闭路试验获得了铜精矿含铜24.15%,铜回收率80.57%;铅精矿含铅31.63%,铅回收率65.35%;锌精矿含锌40.36%,锌回收率83.52%的较好指标。In one ore sample,copper content is 0.933%,lead content is 1.326%,zinc content is 2.346%,and it contains a large amount of pyrite,which belongs to refractory low-grade polymetallic ore.The recommended flow is"partially mixed-preferential flotation"through tests.Copper concentrate was obtained through the closed circuit tests,and its copper content is 24.15%,the copper recovery rate is 80.57%;in the lead concentration,the lead content is 31.63%,the lead recovery rate is 65.35%;in the zinc concentration,the zinc content is 40.36%,zinc recovery rate is 83.52%,targets are better.
