摘　要: 国外某铅锌多金属矿石含铅4.55%、锌5.78%,共生关系复杂,嵌布粒度极细,而且铅、锌矿物可浮性相近。为综合回收各有用矿物,采用"铅锌优先浮选"流程,对该矿石进行了详细的选矿试验研究。最终试验成功实现了铅、锌矿物分离,获得了铅品位51.23%、回收率为86.43%的铅精矿,以及锌品位46.64%、回收率为87.74%的锌精矿。

Abstract: As we made the research on the characteristics of the ore lead- zinc ore that contains lead4. 55%,zinc 5. 78%,we could find that the intergrowth relation is complicated,the dissemination size was fine,and the floatability of lead- zinc mineral is similar. For the comprehensive recovery of the metals in the ore,we used preferential flotation separation processing to recover the valuable mineral from the ore. The result showed that the lead and zinc were separated successfully,the lead grade is 51. 23% and the lead recovery is 86. 43%,and the zinc grade is 46. 64% and the zinc recovery is87. 74%.
Keywords: lead-zinc oxide ore; preferential flotation; lead-zinc separation
