Bauxite residue is a waste product from the aluminium production process. Rich in iron and aluminium, bauxite residue is produced through the extraction o f alumina from bauxite, typically through the Bayer process. The composition of bauxite residue depends on the source and the extraction pr ocess. For every 1 tonne of alumina, 1–1.5 tonnes ...

Bauxite is an aluminum-rich ore composed primarily of hydrated aluminum oxides, and it serves as the main source for extracting aluminum metal. This mineral is significant in various industrial processes and is primarily formed through the weathering of aluminum-bearing rocks under tropical and subtropical conditions, making it an important hydroxide mineral.

A second feature of a Bayer Process shown in Fig. 1.1 is that the bauxite is ground with caustic solutions. In most plants, the ground bauxite slurry is held in stirred vessels for the time needed for the majority of the silica, contained in the bauxite being ground, to form the insoluble desilication product (DSP) (Na 2 O⋅Al 2 O 3 ⋅2SiO 2 ...

Bauxite is the main raw material used in the commercial production of alumina (Al2O3) and aluminium metal, although some clays and other materials can be utilised to produce alumina. Bauxite is a heterogeneous, naturally occurring material of varying composition that is relatively rich in aluminium. The principal minerals in bauxite are gibbsite (Al2O3.3H2O), …
