  • 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 processes.
