Extraction of Copper from Copper pyrite Grade 12 Science
It is mostly purified by electrolytic method. A block of impure copper is anode a strip of pure copper is cathode while solution of CuSO 4 containing dil H 2 SO 4 is eectrolyte. On passing current impure copper dissolves and equivalent amount of pure copper is deposited at cathode. Impurities are collected below anode as anode mud.
