Extraction Process of Aluminium from Bauxite Ore

Alumina Extraction Problem. In the standard Bayer Process for refining bauxite to produce alumina, the dissolution of the alumina in the ore to form sodium aluminate is accomplished in autoclaves under high pressures varying from 70 to 200 pounds per square inch.

Bauxite | The Aluminum Association

Bauxite ore is the world's primary source of aluminum. The ore must first be chemically processed to produce alumina (aluminum oxide). Alumina is then smelted using an electrolysis process to produce pure aluminum metal.

Lateritic Bauxite Deposits – Our Largest Source of Aluminum ...

Although it has a lower aluminium content than some other minerals, gibbsite-rich bauxite is cheaper to mine and process. Other aluminium minerals which may be present in bauxite include diaspore, boehmite (AlO(OH)) and various types of alumina (or Al 2 O 3 ).

Bauxite: The principal ore of aluminum. - Geology

What is Bauxite? Many people are surprised to learn that bauxite is not a mineral.It is a rock composed mainly of aluminum-bearing minerals. It forms when laterite soils are severely leached of silica and other soluble materials in a wet tropical or subtropical climate.
