黄金氰化尾渣综合利用研究与现状

Research Status of Utilization of Gold Cyanide Tailings

在氰化提金工艺过程中会产生大量的氰化尾渣。氰化尾渣由于含有氰化物属于危险固废,但其中含有可回收的Au、Ag、Fe、S、Cu、Pb、Zn等有价矿物,回收氰化尾渣中的有价矿物不仅能保护自然环境,还能产生经济效益。本文根据氰化尾渣的性质介绍了四类氰化尾渣综合利用方法与研究,展望了四类氰化尾渣综合利用的前景与发展方向。

In the cyanide gold extraction process,a large amount of cyanide tailings will be generated.Cyanide tailings are hazardous solid waste due to their presence of cyanide,but they contain valuable minerals such as recoverable Au,Ag,Fe,S,Cu,Pb,Zn,etc.Recycling valuable minerals from cyanide tailings can not only protect the natural environment but also generate economic benefits.This article introduces the comprehensive utilization methods and research of four types of cyanide tailings based on their properties,and looks forward to the prospects and development directions of the comprehensive utilization of four types of cyanide tailings.
