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.

Bauxite mining and alumina refining are the upstream operations of primary aluminum production. This review article describes the industrial processes of bauxite mining and alumina refining and outlines the physical chemical biological ergonomic and psychosocial health risks. PROCESS DESCRIPTION: BAUXITE MINING
The components of bauxite which react with caustic and lime to form insoluble compounds and those components that do not dissolve are called "red mud" and are separated from the alumina rich liquor in clarifi ion by a settling/decantation process followed by countercurrent washing to recover the caustic and alumina values.

Unlike the base metal ores bauxite does not require complex processing because most of the bauxite mined is of an acceptable grade. Ore quality can be improved by relatively simple and inexpensive processes for removing clay known as “beneficiation” which include washing wet screening and mechanical or manual sorting.

The chemical and mineralogical composition of red mud depends largely on the nature of bauxite ore and the extraction process. Thus there is wide variation in chemistry of red mud as follows: Fe 2 O 3 20–60 wt% Al 2 O 3 10–30 wt% SiO 2 02–20 wt% TiO 2 0–28 wt% Na 2 O 2–10 wt% and CaO 2–8 wt%.

Chemical additives flocculants are added to assist the sedimentation process. The bauxite residue sinks to the bottom of the settling tanks then is transferred to the washing tanks where it undergoes a series of washing stages to recover the caustic soda which is reused in the digestion process .
