Production process European Aluminium
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.
