摘　　要：四川某铅锌矿石,由于方铅矿与黄铁矿、闪锌矿等嵌布关系较密切。确定采用优先浮选的工艺流程对该矿石进行回收利用,通过添加组合抑制剂使铅锌矿物有效分离,获得合格铅、锌精矿。最终闭路试验获得,铅精矿品位62.35%、铅回收率86.29%,锌精矿品位55.68%、锌回收率95.00%。One lead-zinc ore in Sichuan,galena had a relatively close relationship with pyrite and sphalerite. Adopting the process of preferential flotation for the ore recovery,by adding the composite depressor,effective separation of lead and zinc mineral was made,and concentrate of lead and zinc was obtained. The ultimate closed test,lead to concentrate grade of62. 35%,lead recovery rate 86. 29%,the zinc concentrate grade of 55. 68%,recovery of zinc 95%.
