  • Purification or Refining of Impure Metals

    Distillation Method. This method is useful for purification of those volatile metals which have low boiling points such as zinc and mercury. In this method, the impure metal is heated to its boiling point in a vessel. The vapours of metal thus formed are collected and cooled in a separate vessel to get pure metal.
