摘　　要：西藏某铜铅锌硫多金属硫化矿,矿物嵌布粒度细、共生关系复杂,且含硫量较高。采用铜铅混合浮选→铜铅分离→尾矿抑硫浮锌浮选工艺流程。最终获得铜精矿铜品位28.22%、回收率85.29%,铅精矿铅品位57.49%、回收率85.61%,锌精矿锌品位44.17%、回收率62.96%,银在铜、铅精矿中的总回收率达到89.7%,实现了矿物的综合回收。One copper-lead-zinc-sulphur polymetallic sulfide deposit in Tibet was finely and complexly disseminated,which contains high sulphur. Flowsheet of copper-lead bulk flotation-separation of copper-lead then flotation of zinc with inhibition of sulphur was adopted. Grade of copper, lead and zinc concentrates were 28.22% ,57. 49% and 44. 17G respectively. Recovery of them were 85. 29%,85. 61% and 62.96G separately. Silver was collected in copper and lead concentrates with a recovery of 89.7%. Comprehensive recovery of this polymetallic sulfide ore was completed well.
