Aluminium is extracted from bauxite through the Bayer process which involves crushing, digestion, precipitation, and calcination.

• Bauxite is first crushed into small pieces

• The crushed bauxite is then mixed with a hot caustic soda solution in a digester vessel

• The resulting slurry is filtered to remove impurities

• The filtered solution is then cooled and aluminium hydroxide is precipitated

• The precipitated aluminium hydroxide is then heated to produce alumina

• Finally, the alumina is...read more
