During extraction of metals, electrolytic refining is used to obtain pure metals. The electrolyte used can be either Silver salt (for refining silver metal) or Copper(ll) sulphate (for refining copper metal). It cannot be Sodium chloride fused as sodium chloride (along with calcium chloride and KF) is used in the extraction of Sodium metal.
