Question

In electrolytic refining, the impure metal is made as _______.

Answer 1

Many impure metals, such as copper, zinc, tin, lead, nickel, silver, and gold, are refined electrolytically.

Complete answer:
Electrolytic refining is a method of using electricity to purify impure metals. In this operation, the anode is impure metal, while the cathode is a pure metal strip. To produce a solution, a soluble salt of the same material as the electrolyte is used.
In metallurgy, refining is the method of purifying an impure metal. Actually, it differs from other processes such as smelting and calcining in that those two require a chemical modification to the raw material, while refining produces a purer finished product that is chemically similar to the original.
Metal ions from the electrolyte are deposited as a pure metal in the cathode when an electric current is transferred, and impure metal from the anode dissolves in the electrolyte as ions. Mud anode is a type of anode that collects metal impurities below the anode.
Pure metal is deposited at the cathode and impure metal is dissolved from the anode when an electric current is passed. Anode mud is a collection of metal impurities that collects below the anode. So impurities such as gold, silver, platinum group metals, arsenic, selenium, and tellurium are recovered during electrolytic refining.
So the impure metal is used as an anode and the pure metal is used as a cathode in electrolytic refining.
So answering to the question, in electrolytic refining, the impure metal is made as anode.

Note:
The traditional current reaches a polarised electrical system through an anode, which is an electrode. A cathode, on the other hand, is an electrode that allows traditional current to escape an electrical system. These two electrodes are used in Electrolytic refining.
