) called alumina. In the Western World, the Bayer 1 process, invented in the 19th century, is by far the most important process used in the production of alumi-num oxide from bauxite. The process has been refined and improved since its inception. Fig. 2.2 shows that the production of alumina is a complex chemical process. The alu-

Alumina Refining. All Australian alumina refineries use the Bayer Process to extract alumina from bauxite. Inputs typically include caustic soda, energy in the form of gas or coal (to produce the required heat and steam for the process), flocculants (to assist the sedimentation process), and water (to recover the caustic soda for reuse).

step is the separation of aluminium oxide from iron oxide and other impurities in bauxite. This is accomplished using a technique developed by Karl Joseph Bayer, an Austrian chemist, in 1888. In the Bayer process, bauxite is mixed with caustic soda, or sodium hydroxide, and heated under pressure.
Bauxite ore processing Plant
Bayer process is the main industrial method in alumina producing. Bayer process is suitable for processing low silicon bauxite with good quality but is not suitable for goethite with aluminum. The production process is that: in the pressure cooking device, caustic alkali is used to leach bauxite so that we can get sodium aluminate solution. Then the sodium aluminate solution is diluted.

Aluminum oxide can also be made in an electric furnace by fusing bauxite or corundum. Suitably doped alumina is the feed material for boules of synthetic ruby and sapphire made by the Verneuil flame-fusion process. Fused alumina is crushed and used as an abrasive, a refractory, a heating element for electrical heaters, and as a filtering mediu m.
