福建某复杂含金矿物的选矿试验研究

Experimental study on mineral processing of a complex gold bearing mineral in Fujian

复杂含金矿石,矿石中含有碳、砷、硫、铅和锌,为了提高回收率,充分利用资源,通过小型浮选试验,采用高效捕收剂和高效抑制剂代替常规的黄药和黑药,浮选回收率达到92%以上,目的矿物得到了更好的回收利用,精矿品位也有较大的提高。

Complex gold-bearing ores contain carbon, arsenic, sulphur, lead and zinc. In order to improve the recovery rate and make full use of resources, a small flotation test was carried out to replace conventional xanthate and black powder with high-efficiency collector and depressant. The flotation recovery rate was above 92%, and the target mineral was better recovered and utilized. The grade of concentrate has also been greatly improved.
