Extraction Process of Aluminium from Bauxite Ore

2016-04-10  The separation of the alumina from the impurities in the bauxite ore is usually accomplished by the Bayer Process. In this process the ground bauxite is leached with caustic soda (NaOH) to produce soluble sodium aluminate (NaAlO2), leaving the impurities in the insoluble residue. The aluminate solution is then decomposed producing Al(OH)3 which is calcined to produce Al2O3. Alumina
