electrorefining of copper process. Dec 17 2019 Electrolytic refining is a process of refining a metal mainly copper by the process of electrolysis As far as the mechanism of the process is concerned during electrolysis a large chunk or slab of impure metal is used as the anode with a thin strip of pure metal at the hode In this setup an electrolyte metal salt aqueous solution depending on ...
Anode plates and stainless steel hode plates are alternately set into the electrorefining cell, where a proper level of DC current is supplied. Dissolved copper from the anode is electrolytically deposited on the stainless steel hode plate. After about 10 days of electrolysis, the hode is lifted out and stripped from the stainless steel plate, resulting in the completion of refined ...
