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. Alumina is a white powder, appearing similar to table salt, which can then be smelted into aluminium metal.
