  • Extraction Process of Aluminium from Bauxite Ore

    Aluminum is the most abundant metal in the earths crust and is a constituent of many minerals However, the material which is highest in aluminum and most free from objectionable impurities is bauxite which, therefore, is practically the only source of the metal under present processesNomenclatureProductionExampleOperationMechanismTechnologyAdvantagesBauxite is the general name given to the hydrated oxides of aluminum It contains varying amounts of combined water and several impurities of which ferric oxide and silica are usually predominant 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
