摘　　要：对云南某微细粒难选次生硫化铜矿石进行选矿试验研究。结果表明,采用一次磨矿、一次粗选、两次精选、两次扫选的闭路试验流程,可获得铜精矿品位为24.10%,回收率为86.79%的技术指标。A beneficiation test of superfine and secondary copper sulphide ore from Yunnan was studied. The results show that copper concentrate grade of 24. 10% and recovery of 86. 79% was achieved through the whole closed trial, which was once rough grinding, once roughing and twice scavenging, then twice cleaning to the rough concentrate.
