Bauxite is not a mineral but a rock with minerals in it. It is a clay-like substance which is pinkish, whitish or reddish in color depending on the amount and type of impurities. It is soft and, when struck with a hammer, does not produce a metallic sound. Its specific gravity is generally around 2.6 and it has a Mohs hardness of 1 to 3.
Bauxite ore is the world's main source of aluminum. Bauxite is a rock formed from a reddish clay material called laterite soil and is most commonly found in tropical or subtropical regions. Bauxite is primarily comprised of aluminum oxide compounds (alumina), silica, iron oxides and titanium dioxide. Approximately 70 percent of the …
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.
