Bayer process - Wikipedia

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 mixture of silica, various iron oxides, and titanium dioxide. The aluminium oxide must be purified before it can be refined to ...

Controlling of the Grade of Bauxite for Aluminum and ...

The main ore of aluminum is bauxite, which is a combination of a number of minerals. The typical bauxite grade useable in the Bayer process consists of 50 - 55 % Al2O3, up to 30% of Fe2O3, and up to 1.5% of SiO2. Bauxite with a concentration of SiO 2 higher than 50% is suitable only for the manufacture of refractories, chemicals, abrasives, and ...

Aluminium production process

ALUMINA PRODUCTION. Bauxite is crushed, dried and ground in special mills where it is mixed with a small amount of water. This process produces a thick paste that is collected in special containers and heated with steam to remove most of the silicon present in bauxites. The ore is loaded into autoclaves and treated with lime–caustic soda.
