黄金冶炼渣中有价金属的综合利用研究

贵金属的提取工艺,普遍采取氰化法,由于其技术成熟、且回收率高,适用于多种贵金属的提取工艺,是现阶段黄金矿山企业应用最为广泛的提金工艺。黄金等贵金属氰化生产中氰化尾渣中的硫和铜、铅、锌等重金属以及浮选残留的氰化物会对堆存场地环境造成影响。因此如何开发冶炼渣中有价金属的综合利用研究,不仅减少对环境造成的影响,也能使炼渣废物利用,创造其价值。本文针对黄金冶炼渣中有价金属的综合利用进行探究。

Comprehensive utilization of valuable metals in gold smelting slag

Cyanidation is widely used in the extraction of precious metals.Due to its mature technology and high recovery rate,it is the most widely used extraction process in gold mining enterprises at present.In the cyanide production of gold and other precious metals,the sulfur,copper,lead,zinc and other heavy metals in the cyanide tailings,as well as the residual cyanide in flotation will affect the environment of the storage site.Therefore,how to develop the research on the comprehensive utilization of valuable metals in smelting slag can not only reduce the impact on the environment,but also enable the utilization of smelting slag waste and create its value.In this paper,the comprehensive utilization of valuable metals in gold smelting slag is studied.
