Refining – Various Methods

Usually, it is a copper refining process against impurities. Firstly, the impure copper is kept in an anode furnace for two steps of refining. Next, iron and sulphur release in the form of iron oxide and sulphur oxide by blowing air. In this step, the iron oxides release from copper and gaseous sulphur oxide emits from furnace by off-gas system.
