A Bayer process comprises grinding and then digestion of bauxite by bringing it into contact with a sodium aluminate liquor. Digestion consists of forming a slurry that is then treated to separate insoluble residues from the sodium aluminate liquor. The liquor is then crystallized and recycled back to green liquor after having been separated from the alumina trihydrate precipitated …

Calcined Bauxite is obtained by calcining (heating) superior grade Bauxite at high temperature (from 850 oC to 1600 oC). This removes moisture thereby increasing the alumina content. Compared to an alumina content of about 57 % to 58 % in raw Bauxite, Calcined Bauxite has an alumina content of 82 % to 86 %. The heating is carried out in rotary ...

grinding and digestion of bauxite in the sodium aluminate liquor, separation and washing of the coarse red mud residue from the sodium aluminate liquor. Other major steps in the process are the precipitation of aluminum hydroxide from the sodium aluminate liquor and the calcination of the aluminum hydroxide to produce aluminum oxide (alumina).

A schematic flow diagram for the proposed beneficia-tion plant is given in Fig. No. 1. In the proposed in-stallation, the run-of-mine ore would be fed to a Double Pitman Jaw Crusher by means of an apron conveyor. The crushed bauxite would be first chuted down to a scalping screen where the larger lumps up to 2-inch size would be separated.

Bauxite is a low-level naturally occurring radioactive material. It contains small quantities of uranium (238U), thorium (232Th), and potassium (40K).7The low-level natural radioactivity present in the ore transfers almost entirely to the solid residue stream during refining—some to sand residue but most to mud residue.
