    The processes involved in the extraction of metal from their ores and refining is called metallurgy.
    The three steps of metallurgy are:
    1)Concentration of ore
    2)Conversion of ore into metal
    3)Refining of impure metal.
    Concentration of ore: The unwanted impurities such as sand, rocky material, earthy particles etc present in an ore are called gangue.
    The method for removing gangue from ore depend on some differences in physical or chemical properties of ore and gangue.
