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 ...
The most common process for making alumina from bauxite is the Bayer process, which was first discovered over 100 years ago but is still in wide use today. About 90% of alumina refineries in the world use the Bayer process. It's very efficient but it can only be used on high quality bauxite with fairly low content of admixtures, especially silicon.
