    This process starts by drying crushed and washed bauxite, usually containing 30–55% Al2O3 [4]. The bauxite is dissolved in caustic soda to form a slurry, heated to temperatures of about 230–520 °F (110–270 °C). This mixture is then filtered to remove the residue called the "red mud" impurities.
