During the electrorefining of a metal, the pure metal is deposited at the cathode.

Here are the steps involved in the process:

1. An electrolytic cell is set up. The impure metal is made the anode and a thin sheet of the pure metal is made the cathode. A solution of a salt of the metal is used as the electrolyte.

2. When electricity is passed through the cell, metal ions from the anode are oxidized and dissolve in the electrolyte. This leaves behind the impurities in the anode, which either fall off as anode sludge or stay in solution.

3. At the same time, metal ions from the electrolyte are reduced at the cathode and are deposited as pure metal.

4. The impurities either remain in solution or fall to the bottom of the cell as anode sludge.

5. The pure metal is then removed from the cathode.
