国内目前有十几家工厂采用湿法炼铜,贵金属金、银均损失在浸出渣中,这是炼铜工艺一大弱点。本文就针对这一课题,研究综合回收金、银的方法,即采用浮选法从铜浸出渣中回收金银。对原矿(铜浸出渣)含金4.60克/吨、含银600.80克/吨。研究了重选法、磁选法、氰化法、浮选法,并研究了浮选过程中各种影响因素如矿浆中可溶性离子的影响、捕收剂 There are currently more than a dozen factories using wet-process copper smelting, precious metal gold, silver loss in leaching residue, which is a major weakness of copper smelting process. In response to this issue, this paper studies a comprehensive recovery of gold, silver method, that is, the use of flotation method from the recovery of copper leaching residue of gold and silver. On the ore (copper leaching residue) gold 4.60 g / ton, silver 600.80 g / ton. Researches on the methods of re-election, magnetic separation, cyanidation, flotation and the influence of various influencing factors such as soluble ions in the flotation process,
