摘　　要：赞比亚某铜钴硫化矿含铜1.25%、钴0.088%。针对该矿石的工艺矿物学特征,进行了不同药剂种类及用量的条件试验,确定了铜钴混合浮选-铜钴分离的工艺流程。闭路试验获得了含铜31.52%、铜回收率为92.32%、含钴0.232%的铜精矿和含钴2.12%、钴回收率67.56%、含铜1.48%的钴精矿的较好指标。A Copper-Cobalt sulfide ore in Zambia containing 1 .25% Cu , 0 .088% Co , based on the charac-teristic of process mineralogy of the ore , the reagent sieving and dosage tests were carried out , and finally the process combination flowsheet of Cu -Co bulk flotation , followed by Cu -Co separation flotation was determined . Good indexes were achieved by the closed -circuit test , and the concentrates of copper and co-balt was obtained , while copper concentrate containing 31 .52% Cu and 0 .232% Co with copper recovery of 92 .32% and cobalt concentrate containing 2 .12% Co and 1 .48% Cu with cobalt recovery of 67 .56% .
