湿法从氰化金泥中提取金、银、铜、铅工艺试验研究

The hydrometallurgical process extracting gold,silver,copper and lead from cyaniding gold mud

提出了一个湿法从氰化金泥中提取金、银、铜、铅的新工艺。该工艺采用WC混合除杂 剂,将氰化金泥中的Cu、Pb、Zn、Ag除去,使产品金的含量达到95%以上,然后利用电解精炼制备出 99.99%的高纯金,银的品位可达99%以上,且可以回收Cu、Pb。其适于在中小黄金矿山推广应用。

The hydrometallurgical process extracting gold, silver, copper and lead is presented. The process removes copper, lead , zinc, and silver by a mixed chemical agent WC from cyaniding gold mud to produce gold content of over 95% following by electrolysis to produce gold of 99.99% purity and silver over 99.00% and recovering copper and lead. The process suits to be used at middle-small gold mines.
