Electrolytic refining of copper

Aug 30, 2021

In the electrolytic refining of copper, the impure copper is made from the anode in an electrolyte bath of copper sulfate, CuSO 4, and sulfuric acid H 2 SO 4. The cathode is a sheet of very pure copper. As current is passed through the solution, positive copper ions, Cu 2+, in the solution are attracted to the negative cathode, where they take

    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
