甘肃某金矿的浮选尾矿无氰浸金试验研究

Experimental Study on Non-Cyanide Leaching of Gold from a Flotation Tailings of a Gold Mine in Gansu

甘肃某金矿石经多级浮选后,浮选回收率仅能达到80%左右,浮选尾矿中金的含量仍达到1.0 g/t~1.3 g/t,通过对该浮选尾矿进行直接浸出的试验研究,对比了氰化钠与无氰浸金剂Y-CD的浸出效果,并优化了无氰浸金剂Y-CD的浸出试验条件,取得了良好的效果,提高了金的回收率。

In some gold mine in Gansu by multistage flotation, the flotation recovery rate can only reach about 80%, the content of gold flotation tailings still reached 1.0 g/t~1.3 g/t, through the experimental study on the direct leaching of flotation tailings, the leaching effect was compared with sodium cyanide free non-cyanide leaching agent Y-CD, and the optimal conditions of leaching of non non-cyanide leaching Kim agent Y-CD, and achieved good results, improve the recovery rate of gold.
