摘要
对某高寒地区难处理含金尾渣进行了提金工艺实验,考察了磨矿细度、浸出剂浓度、浸出时间、温度对金浸出率的影响,在优化条件下,金浸出率可以达到90%以上,金总回收率达到86%以上,经济效益显著。
Experiments on gold extraction from refractory gold tailings was carried out in the alpine area. The grinding fineness,leaching agent concentration,leaching time,the effect of temperature on gold leaching rate were investigated. Under the optimized conditions,the gold leaching rate can reach above 90%,the total gold recovery reached above 86%,with significant economic benefits.
