Clarification/Settling. Chemical additives (flocculants) are added to assist the sedimentation process. 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).

Bauxite is the primary source of aluminium metal, and about 85% of bauxite mined is processed via the Bayer Process to make alumina trihydrate (ATH), then smelter grade alumina (SGA) from which aluminium metal is derived. The respective processes take place in an alumina refinery and aluminium smelter, which may or may not be integrated.
