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 and These properties are useful for identifying bauxite; however, they have nothing to do with bauxite.
Bauxite is a naturally occurring, heterogeneous material composed primarily of one or more aluminum hydroxide minerals, plus various mixtures of silica, iron oxide, titania, aluminosilicate, and other impurities in minor or trace amounts.
