Bauxite, Alumina and Aluminium | SpringerLink

Abstract. The main ore for the production of aluminium metal is bauxite which is refined to produce an oxide, alumina, which in turn is smelted to produce aluminium. Alternative sources of aluminium-bearing materials are being sought, but there is little likelihood of their displacing bauxite to any significant degree in the near future.

2021-12-30 · In the Bayer process, bauxite ore (containing 30 – 55% Al2O3), is digested by washing with a hot solution of sodium hydroxide at 175°C. The slurry is then filtered and sent to a rotary kiln calciner to dry and, under very high temperature (1000°C), is transformed into the fine, white powder known as alumina.
