Primary aluminium production

Molten aluminium is extracted from alumina through a process called smelting. This process is fully electrified and uses a powerful electric current to extract pure aluminium from alumina. After this electrolysis, molten aluminium can be collected from the bottom of the pot. This liquid metal is transferred to the casthouse, where it is purified, alloyed to specification, and then cast into ingots or billets ready for semi-fabrication.
