Abstract:The conditional and enlarged experiments for the technology of purifying the spent copper electrolyte by sulfide precipitation method were carried out. The results showed that, under suitable conditions, most of the arsenic, antimony and bismuth in the spent copper electrolyte could be removed, while the recovery of the nickel would not be affected. How to remove impurity from the sulfide residue was considered too.The experimental results showed that the sulfide precipitation process of purifying the spent copper electrolyte was a feasible method. 

 

Key words: arsenic; antimony; bismuth; spent copper electrolyte; sulfide
