Abstract

Investigations of Cu–Co–Fe alloys dissolution in sulphuric acid solution were conducted. The phase compositions were identified before electrochemical experiments. Anodic dissolution was found to give about 100% current efficiency and was independent of anode composition. Passivation of anodes was not observed. Dissolution was selective; iron and cobalt were transferred into the electrolyte, while copper was left in anodic slimes and/or deposited on the cathode.
