Mining and Refining – Process - bauxite.world-aluminium

The bauxite residue sinks to the bottom of the settling tanks, then is transferred to the washing tanks, where it undergoes a series of washing stages to recover the caustic soda (which is reused in the digestion process). Further separation of the pregnant liquor from the bauxite residue is performed utilising a series of security filters.

TENORM: Bauxite and Alumina Production Wastes | US EPA

Bauxite ore is dissolved in sodium hydroxide, or lye, at a high temperature and pressure. Then, the alumina and bauxite ores are separated by washing out the waste (red muds or sands) from the alumina. Finally, hydrated alumina is crystallized and calcinated (dried in a furnace) to produce solid alumina.
