Bayer process, comprising grinding (L, B) and then digestion (N 2, A) of a bauxite by bringing it into contact with a sodium aluminate liquor ( 20 b, 120 b ). Digestion consists of forming a slurry ( 3 a, 103 ) that is then treated to separate insoluble residues ( 5 a, 105 a ) from the sodium aluminate liquor. The liquor is then crystallized (D) and recycled back to green liquor ( 20, 120 ...

The Bayer process is the principal method for the production of alumina from bauxite worldwide. The modern version of the process (developed in the 1880's) still maintains the key steps of dissolution of alumina-rich minerals into hot caustic solution, separation of the insoluble phases, followed by gibbsite precipitation and calcination of the gibbsite to alumina (Al 2 O 3).
