ABSTRACT
This paper presents the results of laboratory studies on electrowinning of copper and lead from spent leachate obtained by leaching of copper concentrates with ammonium acetate solutions. The effect of electrolyte composition and the electrolysis current density on the process efficiency was investigated. The electrolyte was also pre-treated with ammonia before it was electrolysed under the same above- mentioned conditions.
