摘　　要：内蒙古某微细粒金矿中,金主要嵌布于黄铁矿等硫化矿物内。本文从磨矿细度,捕收剂、调整剂的用量等方面进行浮选试验研究。确定采用一粗两精三扫闭路流程,最终获得金精矿品位20.57g/t,回收率89.19%的较好指标。In a fine gold ore in Inner Mongolia,gold is mainly embedded in sulfide minerals such as pyrite.Flotation tests were carried out in terms of grinding fineness,collector and dosage of adjusting agent.The closed circuit flowsheet with one roughness,Two concentrates and three sweeps was adopted.The gold concentrate grade of 20.57g/t and the recovery rate of 89.19% were obtained.
