Frequently Asked Questions
Where does aluminium come from?
Aluminium is derived from the ore bauxite. First bauxite is mined from typically shallow deposits, and then it is refined into alumina (alumina hydroxide – Al2O3) using the Bayer process at an alumina refinery. The alumina, a powdery white substance, is then sent to an aluminium smelter where it subjected to electrolysis (Hall/Héroult process) which separates out the aluminium metal.
