Abstract

Method for electrolytically refining copper involving precise control of the thiourea concentrations in the copper sulfate, sulfuric acid solution used in the refining whereby improvements are obtained in tankhouse current efficiencies and the quality of the refined copper deposited on the cathodes. Sufficient thiourea is added to the electrolyte feed so that at least above trace quantities are measured in the electrolyte outflow.
