Alumina refining Norsk Hydro
Aluminium oxide (alumina) is extracted from bauxite in a refinery. Alumina is then used to produce primary aluminium. 47 metric tons of bauxite = 2 metric tons of alumina = 1 metric ton of aluminium. Bauxite contains, in addition to alumina, silica, iron oxide and titanic dioxide. The Bayer process is used to extract alumina from the bauxite:

Alumina is symbolised as Al2O3. Alumina has the appearance of white solid like table salt. Alumina has a boiling point of 2980 degree Celsius and melting point of 2040 degree Celsius. Its molar mass is g/mol. The Bayer Process: Alumina is the main components of bauxite, so bauxite is refined in order to produce Alumina.
