提高某高硫铅锌矿铅锌回收率的试验研究

Experimental Study on Increasing of the Recovery Rate of Lead and Zinc from one High Sulfur Lead Zinc Ore

采用铅硫混选-分离-选锌-硫精矿再选锌的原则工艺流程处理某高硫铅锌矿矿石,可以得到铅精矿、主流程锌精矿1及硫精矿再选锌精矿2及硫精矿等精矿产品,铅精矿中Pb铅回收率91.13%,锌精矿中锌回收率94.49%。银绝大部分在铅锌精矿中得到富集,银在铅锌精矿中的回收达到86.22%。

The process flow chart that using the principle of lead and sulfur mixed flotation - separation - zinc separation - zinc recleaning from sulfur concentrate,which is used for treatment of one lead zinc ore with high sulfur;so the concentrates products,such as lead concentrate,main process zinc concentrate 1 and sulfur concentrate,recleaing zinc concentrate 2 can be got;the recovery rate of Pb lead in lead concentrate is 91.13%,the recovery rate of zinc in zinc concentrate is 94.49%. Most of silver can be enriched in the lead-zinc concentrate,the recovery rate of silver in lead-zinc concentrate can reach to 86.22%.
