Detailed Solution

Electrolytic refining is a technique used for the extraction and purification of metals by the process of electrolysis.
Electrolysis means the breakdown of substances through the use of electricity.
In electrolytic refining, the anode is the impure metal to be purified, while the cathode is a thin strip of high-purity metal. The electrolyte used in the solution is metal salt.
When electric current passes through the electrolyte, pure metal from the anode dissolves in the electrolyte and gets deposited at the cathode.
This happens because metal cations are positively charged and they get attracted to the negative electrode.
