Extraction Process of Aluminium from Bauxite Ore

2016-4-11  It is essential that the Al2O3 (alumina) be obtained substantially free from these impurities as otherwise the iron oxide and silica would be reduced and contaminate the metallic aluminum produced in the Hall (or Heroult) Process. 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
