<h3>Extraction Process of Aluminium from Bauxite Ore</h3><p>Extraction Process of Aluminium from Bauxite Ore.  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. </p>
