摘　　要：为了有效地回收硫精矿中的金、银、铜等有价元素,采用了以电化学方法调整矿浆和经电氧化处理的捕收剂在碱性介质中抑硫浮铜的电化学—浮选工艺,从含Au 5.01g/t、Ag17.23g/t、Cu0.67％的硫精矿中浮出了含金、银、铜分别为112g/t、210g/t、18.02％的铜精矿,其回收率分别为74.83％、40.72％、77.74％。采用该工艺无疑将获得明显的经济效益。Elements of gpld,silver,copper in sulphur concentrates can be effectively recovered by means of an electrochemistry-flotation process which includes pulp conditioning of electrochemistry followed by sulphur depression and copper floating in alkaline medium with electro-oxidization treated collectors. 112 g/t of Au,210 g/t of Ag and 18. 02%of Cu have been obtained from sulphur concentrate containing 5. 01 g/t of Au,17. 23 g/t of Ag and 0. 67% of Cu with the recovery of 74. 83%,40. 72% and 77. 74% respectively. This process, no doubt, will, bring about remarkable economic benefits.
