一种金湿法精炼新工艺的试验研究

Experimental study of wet process for gold refining

介绍了一种新的金湿法精炼工艺的试验研究过程及取得的研究结果。研究结果表明 :该工艺采用一种弱酸性混合除杂剂取代了传统金提纯过程中所用的强酸 ,除去金泥中银、铜等元素 ,极大地降低了生产成本 ,并可按要求产出不同品位的产品 ,消除了环境污染 。

The experimental study of a new wet process for gold refining are introduced.This method uses acid salt as remover of impurity in stead of traditional strong acid in the course of gold/silver purification.By using such remover,the impurities as silver,copper etc in the gold slime are removed,therefore the production eost is greatly lowered,the pollution is excluded from environment,the different graded products are produced as requested.Such remover is provided with great use value.
