The bauxite ore contains aluminum trihydrate (Al (OH) 3 ). Alumina refining produces alumina (Al 2 O 3) from the bauxite ore, by exploiting the reversible reaction of the Bayer process 1–3 : The reaction is firstly driven in the sodium aluminate (NaAlO 2) direction by the addition of caustic soda (NaOH) to bauxite.
The bauxite is then transported to the crushing and washing area, reducing the particle size and increasing the available surface area for the digestion stage. The material that is discharged from the mill is called slurry; Digestion: The slurry is pumped to a digester where the chemical reaction to dissolve the alumina takes place. A hot ...
