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.
