The processes involved in the extraction of metal from their ores and refining is called metallurgy.The three steps of metallurgy are 1concentration of ore.2conversion of ore into metal.3refining of impure metal.Concentration of ore the unwanted impurities such as sand,rocky material,earthy particles etc present in an ore are called gangue.
