Bauxite ores are very sticky and usually bring a high humidity. ln the aluminium industry, contrary to current mineral practice, tlows are measured in a humid basis. The main problem is to handle such a difficult material. Wobbler feeders are used to feed lhe ore to the crushers. ln recent days, apron feeders are displacing them.

However, a highgrade bauxite contains up to 60% Al2O3, and many operating bauxite deposits are well below this, occasionally as low as 3040% Al2O3. Because the desired product is a high purity Al2O3, the remaining oxides in the bauxite (Fe2O3, SiO2, TiO2, Organic material) are separated from the Al2O3 and rejected as alumina refinery resides (ARR) or red mud.

Abstract: Bauxite is the major raw material for alumina production, and its Al 2 O 3 grade improvement or desiliion is a necessary process for production of highgrade alumina concentrates from bauxite ores. In practice, flotation presents an effective method for the processing of such ores. However, it is not

Abstract World reserves of bauxite include vast quantities of ore which at present are subeconomic due to high levels of reactive silica that cause expensive loss of caustic soda during Bayer processing. As the economic reserves of high grade ores diminish, attention is turning to how these lower grade ores may be processed at reasonable cost.

Typically, a bauxite resource contains 3060% alumina (Al 2 O 3), and occurs as two main types: trihydrate ("low temperature") bauxite and monohydrate ("high temperature") bauxite . The other main indior of bauxite quality is the silica content, usually reactive silica for a low temperature bauxite or total silica for a high temperature bauxite
