Alumina from Bauxite. Extraction and Production of Alumina ...
Alumina is the common name given to aluminum oxide (Al2O3). Alumina is produced from bauxite, an ore that is mined from topsoil in various tropical and subtropical regions. The Bayer process, discovered in 1887, is the primary process by which alumina is extracted from bauxite.

Is Low Silica in Bauxite a Problem in Bayer Alumina Plant
Now coming to the topic with raised question mark, it's true that low reactive silica in bauxite is considered as a serious process problem as it directly affects the quality of product alumina because of higher silica content in alumina. The SiO2 content in calcined alumina produced in all modern alumina a refinery is controlled at around 0 ...

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 ...
