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:
The aluminium production process European .
Alumina production. Pure aluminium oxide, called alumina, is extracted from bauxite via a process called refining, composed of two steps: a digestion process, using caustic soda, which allows the separation of aluminium hydroxide from the socalled "bauxite residue", followed by a calcination step which removes the water content in the hydroxide.

Bayer process [SubsTech]
Bayer process is the process of refining alumina from bauxite (aluminum ore containing 3050% of hydrated aluminum oxide) by selective extraction of pure aluminum oxide dissolved in sodium hydroxide. Prior to the Bayer process bauxite is crushed and ground in mills to fine particles (max. size "/).
Patent US Bayer process production .
The Bayer process production of alumina hydrate has been practiced since 1888, and the process involves digestion of bauxite with an aqueous caustic medium at elevated temperatures and pressures.

Alumina: Filtration in the alumina production .
The Bayer process. Almost all alumina plants in the world use the Bayer process, patented over 120 years ago [US Patent 515,895 Process of making alumina, Karl Bayer], to refine bauxite to alumina. In this process, a large volume of caustic liquor circulates continuously around the plant.

Processing technologies: Bayer process .
In the first stage of the extraction process, bauxite is processed to aluminium oxide (or alumina as it is also called). By far the most important, and in the western world only, process for producing aluminium oxide is the Bayer process, which was initially developed before 1900 and has subsequently been improved and refined considerably.

Here, the alumina is produced through the continuous fourstage "Bayer Process" involving: Digestion – dissolving bauxite's alumina content. Bauxite is finely ground in mills, and then mixed with a recycled caustic soda solution and steam in digester vessels operating at high temperature and pressure.
