Aug 12, 2022· The main component of bauxite is Al 2 O 3, containing a small amount of Fe 2 O 3, SiO 2, and other impurities. The main objective of bauxite beneficiation is to lower the concentration of reactive silica, and also to increase the alumina content. In addition, bauxite beneficiation can also be used for iron extraction or iron removal.

Free moisture in crude bauxite, as mined, may range from five to 30 percent. To produce dry bauxite, most of the free moisture is removed by heating crude bauxite in rotary drying kilns. Calcined bauxite is produced by heating bauxite to reduce total volatile matter, including chemically combined water, to less than one percent. Approximately

A Rotary Drum Scrubber (diameter 80 cm, length 200 cm, screen opening 2 mm) was applied to upgrade the crude bauxite ores. The research was started by crushing followed by scrubbing and screening. The scrubber is supported by water sprayer to achieve washed bauxite (+2mm of particle sizes) separated from tailing (-2mm of particle size).
