In general, electrolytic refining method contains the pure metal as the anode
Out line the principles of refining metals by the following method:
Zone refining
Electrolytic refining
Vapour phase refining
In general, electrolytic refining is a process of purification of impure metal during which an electric current is passed through an electrolytic cell which contains impure metal as anode, a suitable electrolyte and pure metal as cathode.
