Explain the distillation and liquation methods for the refining of metals.
(N/A) Distillation: This method is very useful for low boiling metals like $Zn$ and $Hg$. The impure metal is evaporated to obtain the pure metal as a distillate.
Liquation: In this method,a low melting metal like $Sn$ is made to flow on a sloping surface. In this way,it can be separated from impurities with higher melting points.
