The influence of phase structure on the dissolution of Cu–Co–Fe alloys in sulphuric acid solution and the metals recovery

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 n...

More Information
Summary: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.
