Bauxite an overview ScienceDirect Topics
The Bayer process starts by dissolving crushed bauxite in sodium hydroxide under pressure at 300 °C to form a supersaturated solution of sodium aluminate at normal conditions of pressure and temperature. The insoluble oxides are then removed and the hydrated aluminium oxide is precipitated as gibbsite by seeding, more frequently, or as metastable bayerite by reduction of pH by carbon dioxide.
