Answer:
Distillation: This method is used for the purification of metals which possess a low boiling point such as mercury and zinc. In this process the impure metal is heated above its boiling point so that it can form vapours.
Liquation: In this method, melting point of the metals are taken into consideration. Metals with low melting points are purified using this process. The melting point of the impurities is higher than the metal. The metals are converted into liquid state by supplying heat at a temperature slightly above their melting point. Pure metal melts and flows down from the furnace leaving the impurities behind.
Electrolysis: In this process the impure metal and a strip of pure metal is used. The crude metal is made to act as an anode and pure metal is made to act as a cathode. They are dipped in an electrolytic bath which contains the soluble salt of the same metal. As electricity is passed through the solution, the less basic metal moves towards the anode mud leaving the more basic metal in the solution. For example copper is purified using this method.
