Question

Define the term refining of metals.

Answer 1

Refining is the method of obtaining highly purified metals by separating the impurities from the ores.

Some of the examples for the refining process of metals are Liquation, Distillation and Electrolytic refining.

Liquation is a partial melting procedure for separating elements of an ore, metal, or alloy.

Distillation is the process of transforming a liquid into a vapor, which is then cooled back into a liquid form.

Electrolytic refining is a way to separate metals that have been produced by refining processes. The impure metal acts as an anode, whereas the pure metal acts as a cathode.
