Bauxite is found in the form of sedimentary rock with minerals in it

Bauxite is found in the form of sedimentary rock with minerals in it. Such rocks are generally formed over a period of time when volcanic activities lead to solidification of the lava and subsequent weathering of this solid in tropical climates in countries like Brazil, Russia, Australia, Spain, Italy etc. It has shades of brown in raw form. This mineral is named as bauxite after the locality at Les Baux (or Beaux), a village in France. The ore was discovered at this place in 1821 (Mindat.org, 2010). Aluminium is found in bauxite in the form of Aluminium Oxide (Al₂O₃) i.e. Alumina. Therefore, with the help of a refining process, Alumina is extracted from bauxite which in turn is converted into Aluminium metal with the help of smelting process.
