摘　　要：氰化金泥为金矿生产黄金过程的中间产物,在前期焙烧-酸浸探索试验的基础上,采用不同成分的金泥进行产业化应用研究,结果表明:铜、锌浸出率大于99%,金、银综合回收率大于99%,金、银产品质量满足国标要求。该工艺原料适用性强,金、银回收率高,同时可较好地综合回收铜、锌。Cyanide gold mud is a intermediate production in the process of gold, on the basis of experiment of roasting and acid leaching in the early stage, experiment of gold mud industrialization application was carried by different components. The results show leaching rate of copper and zinc is greater than 99% , comprehensive recovery more than 99% of gold and silver, product quality meet the national standard requirements. This technology is adaptable to raw materials, of highly ration of gold and silver, at the same time, it can be better comprehensively recovery copper, zinc.
