根据矿石性质,采用优先浮铅→锌硫混浮→锌硫分离的原则流程,试验确定了浮选药剂种类和用量以及工艺技术条件。闭路试验结果:铅精矿含铅48.73%,铅回收率77.44%;锌精矿含锌41.89%,锌回收率71.90%;金在铅精矿中富集,品位54.51g/t,金的回收率达到70%。硫精矿中硫品位27.81%,可作为硫精矿销售。实现了铅、锌、硫、金的综合回收。
According to the nature of the ore, the principle of preferential floatation → zinc-sulfur mixed floatation → separation of zinc and sulfur was adopted. The types and amount of flotation reagents and technical conditions were determined through experiments. The closed circuit test results showed that the lead concentrate contained 48.73% lead and the lead recovery rate was 77.44%; the zinc concentrate contained 41.89% zinc and the zinc recovery rate was 71.90%; gold was enriched in the lead concentrate with a grade of 54.51g / t; Rate reached 70%. Sulfur concentrate sulfur grade of 27.81%, can be used as sulfur concentrate sales. To achieve a comprehensive recovery of lead, zinc, sulfur, gold.
