摘要
为了提高经济效益,对从铅精矿中氰化浸出回收金进行了研究,其盈亏平衡点是金的浸出率≥50.00%,铅浸出率≤3.00%。经细磨、碱浸预处理、高碱高氰浸出、控制浸出矿浆浓度及浸出时间,金的浸出率达85.00%以上,铅浸出率<0.50%,浸出后的尾渣仍作为铅精矿出售。
An experimental research on recovering gold from lead concentrate with cyaniding process was carried out. And the break-even point is that the extraction rate of gold is more than 50.00% while lead less than 3.00%. By fine milling, alkali leaching pretreatment, high-concentration alkali and cyanide leaching, controlling the pulp concentration and leaching time, the extraction rate of gold is up to 85.00% while lead less than 0.50%, and the process doesn＇t influence the sale of lead concentrate.
