(B) In electrolytic refining,the impure metal is made to act as an anode,while a strip of the same metal in pure form is used as the cathode.These are placed in a suitable electrolytic bath containing a soluble salt of the same metal.The more basic metals remain in the solution,while the less basic metals (noble metals) settle at the bottom of the anode as anode mud.Copper is refined using this electrolytic method.Impurities from the blister copper,such as antimony,selenium,tellurium,silver,gold,and platinum,deposit as anode mud. The recovery of these valuable elements often helps offset the cost of the refining process.
