Alumina is primarily derived from bauxite ore through the Bayer process, in which a caustic soda material, in combination with heat and pressure, is used to dissolve aluminum-bearing minerals from the bauxite. Bauxite residue is then separated from the sodium aluminate, allowing alumina to be crystallized from the remaining solution.
