摘要
本文通过对DMSO/H_2O/Cl^-浸出硫化银的理论分析,阐述了以二氯化铜为氧化剂,氯离子为络合剂,在DMSO—H_2O混合溶剂中浸出含银量高的物料的可能性和优点。将该混合溶液用于浸出镍阳极泥中的硫化银,获得了银浸出率高于99％的结果。从浸出液中回收氯化银和浸出剂的再生也是简便易行的。
This paper has explained the possibility and the advantages of leaching the materials containing a quantity of silver in the system of cupric chloride as a oxidaut, chlorion as a complex agent, DMSO-H_2O as a mixed solvent depeuding on theoretical analysis on leaching silver sulfide in DMSO/ H2O/Cl^- system. when the silver sulfide in nickel slime was leached by this mixed solution the result of the silver extraction rate more than 99% was gained.It is simple and feasible to recovery silver chloride from the leaching solution or to relive of leaching ageat.
