Aluminum is the most abundant metal in the earth's crust and is a constituent of many minerals. However, the material which is highest in aluminum and most free from objectionable impurities is bauxite which, therefore, is practically the only source of the metal under present processes.. Bauxite is the general name given to the hydrated oxides of aluminum.
Beneficiation of bauxite to remove silica, calcite, and iron oxides. ... Jigging is a widely used mineral beneficiation process, despite being one of the oldest forms of mineral separation. Usage also extends to industries such as plastics recycling (Ito et al., 2010).
The main component of bauxite is Al2O3, containing a small amount of Fe2O3, SiO2, and other impurities. The main objective of bauxite beneficiation is to lower the concentration of reactive silica, and also to increase the alumina content.

Bauxite Beneficiation The Bayer process is a well-established process for alumina extraction from bauxite, which makes use of caustic soda at high temperature. This method not only dissolves alumina but also reactive silica that is present in the ore, resulting in a higher consumption of caustic soda. For this reason an Al/Si
For bauxite refining the Bayer process—that separates the valuable alumina from the surrounding materials involves caustic materials, high temperatures, and pressure. The resulting waste stream, especially from bauxite, is a slurry generally known as "red mud," that must be kept in holding ponds until the toxicity of the solution is ...
