Bauxite is a combination of minerals, and is the principal ore of aluminum. Considered and sedimentary rock formed by weathering aluminosilicate rocks.

For the production of alumina, which is used for aluminum production, we need a bauxite, which contain :

  • More than 45-50% Al2O3
  • Less than 20% Fe2O3
  • Up to 5 % Si

Most common uses for Bauxite are:

  • The main ore export aluminum. The main use (approximately 85 % of the produced bauxite used for aluminum production).
  • Material grinding at high temperatures: When heated to melt, it gets crystallized, obtaining high hardness, giving abrasive properties.
  • Manufacture of refractory materials.
  • Construction of fast setting cement (diasporic bauxite).
