云南保山矽卡岩型铜铅锌共生矿选矿扩大试验

Study on the pilot test of copper-lead-zinc skarn sulphides in Baoshan Yunnan

摘要: 在选矿扩大试验条件下对云南保山地区矽卡岩型铜铅锌共生矿进行了浮选试验研究，并取得了较好的选矿指标。扩大试验选矿指标为：铜精矿铜品位18.57%，回收率78.04%；铅精矿铅品位67.37%，铅回收率58.26%；锌品位49.11%，锌回收率88.57%。为开发该矿提供了选矿技术依据。

Abstract: In the present paper flotation research on skarn-type Cu-Pb-Zn associated mine in Baoshan Yunnan was carried out during pilot test and obtained much better flotation index. Then copper concentrate with Cu grade of 18.57% at an 78.04% recovery, lead concentrate with Pb grade of 67.37% at an 58.26% recovery and zinc concentrate with Zn grade of 49.11% at an 88.57% recovery are obtained respectively. A refined beneficiation test indicator had been obtained, which provides a basis for reasonably recovering these mineral resources.
