उत्तर
Distillation
Explanation:
Distillation is used for the purification of metals having low boiling points and which are liquid at or near room temperature, such as zinc, mercury, and cadmium. The impure metal is heated so that it vaporises and then condenses, leaving the non-volatile impurities behind.
