摘要
某低品位难选金矿含金0.86 g/t,根据其性质特点,采用MA和丁胺黑药组合药剂,进行磨矿-二粗一扫三精的浮选工艺流程试验,最终可获得精矿金品位21.40 g/t,回收率84.41%的浮选闭路指标,金得到很好的回收。
The gold content of a low grade gold ore is 0.86 g/t.On the basis of the distinguishing feature of this ore,using composite reagents of MA and butyl-amine dithiophosphate,the flotation technical process experiments for grinding-two roughing-one scavenging and three cleaning were carried out.Finally closed circuit flotation targets of containing gold 21.40 g/t and recovery 84.41% for the concentrate were obtained.The very good recovery for gold was obtained.
