摘　　要：云南某金矿开采已有近百年的历史,由于历史遗留问题在民采过程中地表上堆存了大量的氰化尾渣,含金量在(3~4) g/t,具备一定的回收利用价值,针对上述情况开展一系列试验研究,该氰化尾渣处理方式采用重+浮联合工艺,尾渣中金回收率可达85.57%,实现对有价金属的充分回收。Mining of one Yunnan gold mine has hundreds of years of history up to now,a large amount of cyanidation tailings is stockpiled on the earth’s surface in the process of folk mining due to historical problems,which has gold content ofabout(3~4)g/t,it has a certain recycling utilization value,then a series experimental studies were carried out for above mentioned situation,the joint process that gravity separation+flotation were adopted for treatment of the dyanidation tailings,gold recovery rate can reach to 85.57%,the sufficiently recovering of valuable metals can be realized.
