摘　　要：印尼某铅锌矿石属于含碳多金属硫化矿石。根据其矿石性质,采用预先除碳—浮铅—再选锌的优先浮选工艺流程进行铅、锌分离试验研究。其结果表明:在最佳条件下,浮选闭路试验获得了铅品位51.16%、锌品位4.37%、铅回收率87.15%的铅精矿,锌品位57.42%、铅品位0.73%、锌回收率81.80%的锌精矿,指标较好。One lead- zinc ore in Indonesia is a carbonaceous polymetallic sulfide ore. According to the ore property,a preferential flotation process was adopted,during which carbon was removed first,and then lead was floated before zinc was recovered,to conduct the experimental study on lead and zinc separation. The results show that under optimal conditions,closed circuit flotation can obtain a lead concentrate with lead grade of 51. 16 %,zinc grade of 4. 37% and lead recovery rate of 87. 15 %; and a zinc concentrate with zinc grade of 57. 42 %,lead grade of 0. 73 % and zinc recovery rate of 81. 80 %,indicating satisfactory indexes.
