REFINING OF BLISTER COPPEROREGANGUEUSES OF LEAD .
REFINING OF BLISTER COPPER : Blister copper is refined by an electrolytic process. Blister copper in the form of a large plate is made as anode. A thin plate of pure copper is cathode. A solution of CuSO 4 is used as an electrolyte. The impure blister copper dissolves at the anode.
