· The Bayer process is an industrial process by which bauxite is purified into alumina, or aluminum oxide. Named for Karl Bayer, who developed it in the late 19 th century, this process is an essential intermediate step in the production of aluminum metal.
The production of primary aluminium consists of three steps: bauxite mining, . Bauxite has to be processed into pure aluminium oxide (alumina) before it . This is achieved through the use of the Bayer chemical process in alumina refineries. .. The process of producing pure alumina from bauxite has changed very little . »More detailed
Bauxite deposits are formed chiefly by weathering of aluminous rock; some have been transported to their present locations, but most are residual accumulations from which most other constituents of the parent rock, other than alumina, have been leached. Bauxite deposits occur in rocks ranging in age from Precambrian to Holocene.

The Bayer process is the principal industrial means of refining bauxite to produce alumina (aluminium oxide) and was developed by Carl Josef Bayer. Bauxite, the most important ore of aluminium, contains only 30–60% aluminium oxide (Al 2 O 3), the rest being a .
Bauxite is the main source of the rare metal gallium. During the processing of bauxite to alumina in the Bayer process, gallium accumulates in the sodium hydroxide liquor. From this it can be extracted by a variety of methods. The most recent is the use of ion-exchange resin.
