Copper Refining - an overview ScienceDirect Topics

In the electrolytic process, copper is electrodeposed to obtain a spongy powder deposit at the cathode rather than a smooth, adherent one. In this feature, it differs from the process of copper refining where a strongly adherent product is desired. Low copper ion concentration and high acid content in the electrolyte favor formation of powder deposits.
