Bauxite

The principal ore of aluminum is bauxite, a complex mixture of a number of aluminum hydroxides and hydrous aluminum oxides. The most common aluminum-bearing minerals in bauxite are gibbsite (AlOH3), boehmite (AlO(OH)), and diaspore (AlO(OH)). In the Arkansas deposits, diaspore has not been reported.

What is Bauxite? | Rock & Gem Magazine

Rough bauxite stone. Bauxite is a sedimentary rock that consists mainly of the basic aluminum oxide mineral gibbsite [aluminum hydroxide, Al(OH)3], and the dimorphic minerals böhmite and diaspore [both basic aluminum oxide, AlO(OH)]. Lesser amounts of the iron oxides goethite [FeO(OH)] and hematite [Fe2O3] impart bauxite's reddish hue.
