摘　　要：某硫化铜金矿原矿Cu和Au品位分别为3.27%和2.35 g/t,针对铜的赋存状态及粒度嵌布特点,进行了浮选工艺研究。确定了最佳试验条件为:磨矿粒度为-0.074 mm粒级占70%,pH=8.5,采用BY-309与B-5050组合作捕收剂,用量分别为110 g/t和55 g/t,一粗三精三扫闭路试验获得了含Cu 18.87%、Au 13.587 g/t的铜金混合精矿,铜、金回收率分别达到了92.70%与89.53%,实现了硫化铜金矿综合高效回收。In view of the occurrence state of copper minerals and dissemination size of a copper sulfide gold ore with Cu grade of 3.27% and Au grade of 2.35 g/t, flotation technique was studied. With the optimized grinding fineness of -0. 074 mm 70% , at pH value of around 8.5, by adopting a combined collectors of BY-309 and B-5050 with the dosage of 110 g,/t and 55 g/t, respectively, a copper-gold bulk concentrate graded at 18.87% Cu and 13. 587 g/t Au, with Cu and Au recovery of 92.70% and 89.53%, respectively, consisting of one stage of roughing , three stages of cleaning and comorehensive recovery of coooer sulfide gold ore was realized. can be obtained adopting a closed-circuit flowsheet three stages of scavenging. Therefore high efficient
