摘要
采用湿法预处理除铜 -氨氰法研究了从含 Cu、Pb金精矿中提取 Au、Ag的新工艺方法。它与常规方法相比 ,Au、Ag的回收率分别提高了 34 .78%和 1 2 .52 % ,对于中小型黄金矿山具有推广价值。
The new extraction technics of gold and silver from Cu,Pb bearing gold concentrates is studied by using wet preprocessing to remove Cu and ammonia cyanidation process. Comparing with the general technology, it can raise the recovery ratios of Au and Ag, to 34.18% and 12.52% respectively. It is valuable to spread in the middle or small gold mines.
