This process entails dissolving the alumina in cryolite a molten solvent An electrical current is run through the mixture causing the carbon from the

Aluminium Rio Tinto

Aluminium is made from bauxite or aluminium ore Bauxite is the basic raw material that is refined into alumina which in turn is sent to smelters for processing into aluminium First discovered near Les Beaux in the South of France in 1821 bauxite was initially called “beauxite” In 1886 Charles Martin Hall and Paul Héroult

Bauxite Mining and Alumina Refining PMC

201458 The bauxite ore contains aluminum trihydrate Al OH 3 Alumina refining produces alumina Al 2 O 3 from the bauxite ore by exploiting the reversible reaction of the Bayer process 1–3 The reaction is firstly driven in the sodium aluminate NaAlO 2 direction by the addition of caustic soda NaOH to bauxite
