摘　　要：针对某低品位铜铅锌硫化矿,采用铜铅顺序优先浮选—锌硫混合浮选再分离工艺进行了浮选分离试验研究。选用高效选择性铜捕收剂BK916和铅捕收剂BK906进行了铜铅顺序优先浮选试验研究,并在锌硫分离试验研究中,利用环保型抑制剂BD和石灰的组合作用,有效抑制了锌硫混合精矿中的黄铁矿,获得了铜品位20.68%、铜回收率72.98%的铜精矿;铅品位61.38%、铅回收率73.57%的铅精矿;锌品位46.31%、锌回收率73.17%的锌精矿和硫品位48.54%的硫精矿。For a low grade copper-lead-zinc sulfide ore,the flotation separation experiment was carried out by the process of preferential flotation of copper-lead—zinc-sulfur mixed flotation and zinc-sulfur separation.A high-efficiency and selective copper collector BK916 and lead collector BK906 were used to conduct a copper-lead sequential preferential flotation test study.In the experimental study of zinc-sulfur separation,the combination of environmental protection inhibitor BD and lime effectively inhibited the pyrite in zinc-sulfur mixed concentrate.It can obtain copper concentrate with copper grade of 20.68%and copper recovery rate of 72.98%,lead concentrate with lead grade of 61.38%and lead recovery rate of 73.57%,zinc concentrate with zinc grade of 46.31%and zinc recovery rate of 73.17%,and sulfur concentrate with sulfur grade of 48.54%.
