Effect of bauxite aggregate in cement composites on …
Note that the aggregate crushing value of the bauxite aggregate (8.0%) is much smaller than that of the granite aggregate (32.7%), which is consistent with that reported in Ref. [1]. For coarse aggregate, a higher aggregate crushing value generally corresponds to a lower compressive strength (Fig. 1). It is thus reasonable to assume …

The resulting sodium aluminate-rich liquor is separated by physical means, such as settling and filtration, from the insoluble residue, known as bauxite residue. Typically, depending on the type of bauxite used, 1 t of alumina results in the generation of residues varying from 0.3 t for high grade to 2.5 t for very low-grade bauxite [9, 10].

Bauxite: The principal ore of aluminum.
Physical Properties of Bauxite. Bauxite is typically a soft material with a hardness of only 1 to 3 on the Mohs scale.It is white to gray to reddish brown with a pisolitic structure, earthy luster and a low specific gravity of between 2.0 and 2.5. These properties are useful for identifying bauxite; however, they have nothing to do with bauxite's value or usefulness.
