Production process
Pure aluminium oxide, called alumina, is extracted from bauxite via a process called refining, composed of two steps: a digestion process, using caustic soda, which allows the separation of aluminium hydroxide from the socalled "bauxite residue", followed by a calcination step which removes the water content in the hydroxide.

How Aluminum is Produced
The smelting process required to produce aluminum from the alumina is continuous the potline is usually kept in production 24 hours a day yearround. A smelter cannot easily be stopped and restarted. If production is interrupted by a power supply failure of more than four hours, the metal in the pots will solidify, often requiring an expensive rebuilding process.
