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 (Al2O3), 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.

Bauxite - an overview ScienceDirect Topics

The residues from the bauxite production in Jamaica contain more than two times REEs (2000–3000 ppm), which are in particular, enriched in scandium (150 ppm) than the original bauxite (Wagh and Pinnock, 1987). Thus, there is a potential to produce REEs from red mud as by-product of alumina, which is explored by the Jamaica Bauxite Institute.
