摘　　要：为了综合回收利用内蒙古某黄金矿山堆浸尾矿中的金、银,采用无氰浸出工艺,选用新型无氰环保药剂作浸出剂,在矿浆质量浓度33%、pH=11、浸出剂用量2.0 kg/t、浸出时间24 h的条件下,金浸出率达52%,银浸出率约59%,浸出指标稳定。该工艺简单易行,可实现尾矿资源的二次利用,并能取得较大的经济效益。In order to recycle the gold and silver in the tailings of gold ores from Inner Mongolia, a noncyanide leaching process with a new type of non-cyanide leaching agent was used. The pulp density was33%, pH value was 11, the leaching agent was 2.0 kg/t, and the leaching time was 24 h. The results showed that, the gold leaching rate was over 52%,while the silver leaching rate was about 59 %. The leaching indexes were stable. This process is simple and easy to operate, and it not only can recycle the tailing ores, but also can achieve great economic benefits.
