摘要
对四川某复杂高硫铜铅锌矿进行了工艺矿物学研究后,采用部分混合浮选流程,铜铅混浮—铜铅分离—混浮尾矿选锌,最终获得铜品位17.5%,回收率为51.80%的铜精矿,铅品位为60.10%、回收率为79.51%的铅精矿,锌品位为47.01%、回收率为78.64%的锌精矿,硫品位为38.92%、回收率为72.64%的硫精矿,同时铜铅分离生产验证试验取得良好指标。
Studied the technological mineralogy of a Copper-Lead-Zinc poly metallic ore which contain highly pyrite from Sichuan province, then the closed-circuit of copper-lead mixed flotation-copper-lead separation- zinc flotation form tailings was established. The results indicated that it could obtain the copper concentrate with 17.5% grade and 51.80% recovery; the lead concentrate with 60.10% grade and 79.51% recovery; the zinc concentrate with 47. 01% grade and 78.64% recovery; the sulfur concentrate with 38.92% grade and 72.64% recovery. At the same time, the separation of copper and lead production verification test achieved good indicator.
