摘要: 从含砷金矿石中回收金一直是浮选研究的重要课题。试验采用石灰、亚硫酸氢钠和少量氰化物作为毒砂的抑制剂及适宜的选别流程,可以有效实现金与毒砂的分离。金精矿含砷0.27%,砷的脱除率92.68%;金精矿金品位82.30 g/t,金回收率87.01%。

Abstract: Gold recovery from arsenic-containing gold ore has been a major subject of flotation research. In this research, lime, sodium bisulfite and small amount of cyanide as the depressors for arsenopyrite and a suitable process were adopted to realize an effective separation of gold from arsenopyrite, with the gold concentrate containing 0.27% arsenic at an arsenic removal rate of 92.68% and the gold concentrate grading 82.30 g/t at a gold recovery of 87.01%.

Key words: Arsenic-containing gold ore, Arsenopyrite, Flotation
