摘　　要：针对全泥氰化工艺尾水开展100t/d工业试验研究,开发纳滤、反渗透二段浓缩铜银络合离子工艺,通过置换、中性萃取、酸性反萃、电积全新工艺技术,在不改变尾水理化性能的条件下,实现了活化游离氰根,提高金、银浸出率,综合回收电积铜的目的。The 100t/d industrial experiments for tail water from whole mud cyanidation process were carried out.New technologies of nanofiltration,and reverse osmosis two-step concentration of complex ions of copper and silver were developed.Activation of free cyanide,improvement of leaching rate of gold and silver,comprehensive recovery of electro-deposit copper were realized through replacement,neutral extraction,acidic stripping,and electrowinning without changing physical and chemical properties of tail water.
