Bayer process - Wikipedia

The Bayer process is the principal industrial means of refining bauxite to produce alumina and was developed by Carl Josef Bayer. Bauxite, the most important ore of aluminium, contains only 30–60% aluminium oxide, the rest being a mixture of silica, various iron oxides, and titanium dioxide. The aluminium oxide must be purified before it can be refined to aluminium metal.

BAYER PROCESS Bayer process is the process of refining alumina. from bauxite (aluminum ore containing 30-50% 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 0.06”/1.5mm).

Bayer Process - an overview | ScienceDirect Topics

The Bayer process extracts alumina by caustic digestion of crushed bauxite at high temperature and pressure in an autoclave, followed by clarification, precipitation, washing and finally calcination to produce pure anhydrous alumina. Some aluminium producers own, or partly own, alumina refineries.

Mining and Refining – Process - World Aluminium

Alumina is used for the production of aluminium metal, through the Hall–Héroult electrochemical smelting process. The Bayer Process is the most economic means of obtaining alumina from bauxite. Other processes for obtaining alumina from metal ores are also in use in some refineries, particularly in China and Russia, although these make up a relatively small percentage of global production.
