Answer:

Distillation

This is very useful for low boiling metals like zinc and mercury. The impure metal is evaporated to obtain the pure metal as distillate.

Vapour Phase Refining

The metal is converted into its volatile compound and collected elsewhere. It is then decomposed to give pure metal.

There are 2 requirements for this method:-

The metal should form a volatile compound with an available reagent,

The volatile compound should be easily decomposable, so that the recovery is easy.
