I hope its helpful for u

Answer 2

$\huge{\tt\pink{Answer:}}$

Electrorefining of metals

Electrorefining is a process in which materials, usually metals, are purified by means of an electrolytic cell. The anode is the impure metal and the cathode is a very pure sample of the metal. An electric current is passed between a sample of the impure metal and a cathode when both are immersed in a solution containing cations of the metal. The metal is stripped off the impure components and deposited in pure form on the cathode.
