उत्तर
Electrolytic refining of copper
When current flows through the electrolyte, the impure metal dissolves from the anode into the solution. Positive copper ions travel towards the cathode, which is pure copper. Metal cations receive electrons from the cathode and deposit them as \[\ce{Cu}\] atoms, producing pure copper at the cathode.
