云南某地硫化铅锌矿优先浮选分离试验研究

Experiment Research on Preferential Flotation Process for the Lead-zinc ore from Yunnan

针对云南某地硫化铅锌矿,采用优先浮选流程进行试验研究,获得铅精矿产率4.26%、铅品位60.14%,铅回收率90.53%;锌精矿产率5.01%、锌品位51.78%,锌回收率87.64%;伴生银富集在铅精矿中回收,银品位642 g/t、银回收率76.33%的较好指标,可为矿山开发可研、选厂设计及生产技术服务提供充分可靠的技术依据。

In this paper, the preferential flotation process was adopted in Yunnan lead-zinc ore, which obtained lead sulfide concentrate with the yield of 4.26%,the lead of 60.14% and recovery of 90.53% , zinc sulfide concentrate with the yield of 5.01% the zinc of 51.78% and recovery of 87.64% the associated silver was concentrated in lead concentrate, the silver of 642 g/t and recovery of 76.33%,which can provide sufficient and reliable technical basis for mining feasibility study, mill plant design and production technical services.
