Flowsheet of Bayer Process Steps in Bayer process : (1) Ore Preparation : It is important to do ore preparation to reduce total precentage of silica in boxite. Using crushing and grinding, the silica content reduced from 10% to 1.5% as bauxite tends to get concentrated in the finer fractions (i.e., -100 mesh).

Bayer process 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. [1]
