Bayer process Wikipedia
The Bayer process is the principal industrial means of refining bauxite to produce alumina (aluminium oxide) and was developed by Carl Josef Bayer. Bauxite, the most important ore of aluminium, contains only 30–60% aluminium oxide (Al2O3), the rest being a mixture of silica, various iron oxides, and titanium dioxide. The aluminium oxide must be purified before it can be refined to aluminium metal.

Pentair Alumina refinery
The Bayer process is the most economical means of refining bauxite to alumina (aluminum oxide). The process involves the removal of organic components with the help of caustic soda in what is called a liquor burning plant. The liquor is concentrated by evaporation and combusted in a rotary kiln.

Red mud Wikipedia
2021. 4. 5. Red mud is a side-product of the Bayer process, the principal means of refining bauxite en route to alumina. The resulting alumina is the raw material for producing aluminium by the Hall–Héroult process. A typical bauxite plant produces one to two times as much red mud as alumina.

Alumina Production an overview ScienceDirect Topics
The Bayer process is used to produce over 90% of the world alumina production. The key steps used to produce metallurgical grade alumina from bauxite ore are described including the extraction of alumina trihydrate, removal of iron oxide and silicon dioxide impurities, generation of red mud residue, precipitation of alumina trihydrate crystals, and calcination of gibbsite.

Simplistically the Bayer process solubilizes alumina from a bauxite, then an alumina-rich liquor is separated from the inert solids. Alumina is then concentrated from the liquor by a seeding procedure.
