摘　　要：我国黄金矿山尾矿逐年增加,给社会和环境都带来了巨大压力和潜在危险。而黄金行业的氰化提金工艺又常使金矿中伴生的铜铅锌等有价元素留在尾渣中,却未能有效综合回收利用,造成了铜铅锌铁硫等资源的浪费。本文分析了氰化尾渣的二次利用价值,综述了国内目前从氰化尾渣中回收铜铅锌金属的工艺现状及其研究成果,指出了未来发展趋势和研究方向。The gold mine tailings in China have increased year by year,which has brought great pressure and potential risks to the society and environment.Cyanide processes in gold industry often make copper,lead,zinc and other valuable elements remain in residues.The effective comprehensive recovery of these valuable minerals is difficulty.This article analyzes the huge recyclable value of cyanide tailings,which have a great necessity to recover,and summarizes the technology status and research findings about the currently recovering copper,lead,zinc from cyanide tailings.At the end of this article,it states the development trend and research direction of recovering copper,lead,zinc from cyaniding tail slag in the future.
