摘　　要：针对某有色金属公司在铜阳极泥回收处理过程中出现的铂、钯金属回收率低,金的直收率不够高等情况,应用物质流方法对其处理铜阳极泥中的金、银、铂、钯等贵金属的行为进行研究。结果表明:在目前阳极泥处理工艺中,金、银的分布比较集中,粗金粉富集了阳极泥中近88%(质量分数)的金;97%左右的银集中于粗银粉中;铂与钯分布较分散,铂钯精矿、沉氯化银后液、析铂钯后液以及分银渣中都含有金属铂和钯,其含量都分别在53%、14%、26%和8%左右。The low recovery rates of Pt and Pd,and low direct recovery of Au are the main problems needed to be solved in the process of copper anode slime treatment for a non-ferrous metal company.The substance flow analyses（SFA） were used to study the behaviors of the precious metals such as Au,Ag,Pt and Pd.The results show that almost 88% Au and 97% Ag are enriched in the crude Au powder and crude Ag powder,respectively.However,Pt and Pd distribute scatteredly in the Pt-Pd concentrate,AgCl precipitated solution,Pt-Pd precipitated solution and Ag leached residue,with the amounts of Pt and Pd of 53%,14%,26% and 8%,respectively.
