About Bauxite

  • Introduction: This mineral ore is primarily composed of aluminium oxide (Al₂O₃).
    • It is the primary source of aluminium metal.
  • Chemical Composition
    • Main constituents: Aluminium oxide (40-60%).
    • Other elements: Iron oxide, silica and titanium dioxide
    • Present as hydrated aluminium oxides such as gibbsite, boehmite and diaspore
  • Origin and Geology
    • Formed by weathering in tropical and sub-tropical regions.
    • Found in laterite soils, which are formed by the weathering of aluminium-rich rocks.
  • Uses
    • Aluminium production: Bauxite is purified by the Bayer process to make alumina, which gives aluminium metal.
    • Important in aluminium products such as aeroplanes, utensils, packaging and construction materials.
  • Other uses: Abrasives, cement, chemical industry.
