  • Refining of impure metals | Fun Science

    So, it is to be purified. The method used for refining of metal depends on the nature of metal and impurities present in it. Some common methods which are used for purification of impure metals are: 1. Distillation Method. This method is useful for purification of those volatile metals which have low boiling points such as zinc and mercury.

  • Zinc: smelting, producing and classification-Metalpedia

    Zinc is extracted from the purified zinc sulfate solution by electrowinning, which is a specialized form of electrolysis. The process works by passing an electric current through the solution in a series of cells. This causes the zinc to deposit on the cathodes (aluminium sheets) and oxygen to form at the anodes.
