摘　　要：对某难处理含金石英脉矿石进行了高效利用试验研究,采用浮选可获含金54.20g/t,金回收率为73.23%的金精矿和含金1.43 g/t的尾矿。对金精矿和尾矿分别进行氰化浸出处理,获得了回收率53.49%的贵液和回收率36.21%的金精矿浸渣(含金26.80 g/t),金总回收率达到89.70%。该浮选—精尾分浸工艺流程为该难选金矿提供了较好的开发利用方案。The efficient utilization of a refractory gold ore was investigated. The results indicated that gold concentrate containing gold 54.20 g/t at recovery of 73.23% and tailing containing gold 1.43 g/t could be obtained by flotation. Cyanide leaching process was used to treated the gold concentrate and tailing. Pregnant solution with recovery of 53.49% and leaching slag of gold concentrate at recovery of 36.21% were produced. The total recovery of gold could reach 89.70%. The process of flotation and cy- anide leaching provides scheme for developing and utilizing of this refractory gold ore.
