Electrolytic refining

Vedclass · Answer

(C) The most common and effective method for the refining of copper metal is $Electrolytic$ $refining$. In this process, an impure copper block is used as the anode, and a thin strip of pure copper is used as the cathode. An aqueous solution of copper sulfate $(CuSO_4)$ mixed with dilute sulfuric acid $(H_2SO_4)$ is used as the electrolyte. When an electric current is passed through the solution, pure copper from the anode dissolves into the electrolyte and deposits onto the cathode, while impurities settle at the bottom of the anode as 'anode mud'.
