Aluminium, Alumina and Bauxite
Alumina is the key raw material used to produce primary aluminium. Mined bauxite ore is refined into alumina through what is known as the Bayer process. The process, discovered in 1887, extracts alumina from bauxite through crushing, dissolving it in caustic soda, filtration and an electrolytic process.
