This method is applied to those metals which contain impurities as their own oxides. The crude metal is melted in a big container and is then stirred with green poles of wood. Gaseous hydrocarbons (CH4, C2H6, C2H4, etc) are released from green poles which reduces the oxides of metals to the pure state by taking up oxygen. Copper is purified by Poling Process.
