Bayers Process Of Bauxite Concentration

Bayer process - Wikipedia

 · The Bayer process is the principal industrial means of refining bauxite to produce alumina (aluminium oxide). Bauxite, the most important ore of aluminium, contains only 30–60% aluminium oxide, (alumina), Al 2 O 3, the rest being a mixture of silica, various iron oxides, and titanium dioxide.
