Bauxite: Formula, Types & Uses
Bauxite is primarily a metallic mineral, which is the only ore used for large-scale aluminium production. It is a sedimentary rock which contains relatively high levels of aluminium. Bauxite is the main source of aluminium and gallium. It appears dull in lustre and is reddish-brown, white, or tan in colour. The rock was discovered in 1821 near ...

Bauxite | Formula, Properties & Application
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.

A pit 10-40 feet deep and 200 feet long was dug into the kaolin and bauxite-rich ore body to expose ore of up to 57.5 percent aluminum oxide (Al 2 O 3). Approximately 4 miles to the northeast, the Allen Mine opened in 1941. A pit at least 50 feet deep and 120 feet long was excavated to access the ore body within residuum above Beekmantown dolomite.

The bauxite ore in this profile is dominated by Al with small amounts of Ti, Si, and Fe 2+. Both Al and Si have roughly uniform concentrations throughout the bauxite, whereas Ti and Fe 2+ generally decrease in concentration upwards. The bauxite ore contains significant amounts of S, Zr, Nb, F, and Cr, and contains up to 16,649 ppm S.
