alumina is produced from bauxite an ore that is mined from topsoil in various tropical and subtropical regions. the bayer process discovered in 1887 is the primary process by which alumina is extracted from bauxite. to produce pure aluminum alumina is smelted using the hall héroult electrolytic process.
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. bauxite residues are then removed leaving the process liquid termed “green liquor.”
