extraction of iron from its ore

  • extraction of metals from concentrated ore: reduction of

    extraction of metals. now we already saw how the ore of a metal is concentrated to remove impurities known as gangue. after concentration of ores we must now extract metal from in it. this step will give us metal in its pure form i.e. the native form of metal. first we must convert the ore to a suitable form.inquire now
