  Bayer process

  Bauxite ore is a mixture of hydrated aluminum oxides and compounds of other elements such as iron. The aluminium compounds in the bauxite may be present as gibbsite 2(Al(OH) 3), böhmite (γAlO(OH)) or diaspora (αAlO(OH)); the different forms of the aluminium component and the impurities dictate the extraction conditions. Aluminum oxides and hydroxides are amphoteric, meaning that they are ...
