Aluminum extraction process

In the electrolytic extraction of aluminium, the anodic process is the discharge (or oxidation) of the oxide ion, O 2−. The net process is the decomposition of the feed alumina, Al 2 O 3, into aluminium metal and oxygen, which in turn reacts with the carbon (anode) to produce CO 2 at elevated working temperatures (e.g. 900 C). The process
