    Electrowinning And Electrorefining Of Copper Murdoch

    Copper electrorefining. In the electrorefining of copper, anodes of impure copper are suspended in an electrolyte solution, adjacent to cathodes of pure copper. Electrical current is passed between the anodes and cathodes, through the electrolyte, in such a way as to cause copper to dissolve from the anodes and deposit onto the cathodes.

    In Electro Refining Of Copper Some Gold Is Deposited As

    In Electrolytic refining, the impure metal is made to act as an anode. A strip of the same metal in pure form is used as the cathode. They are put in a suitable electrolytic bath containing a soluble salt of the same metal. The more basic metal remains in the solution and the less basic ones go to the anode mud. Copper is refined using an electrolytic method.
