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.

The principal minerals in bauxite are gibbsite (Al 2 O 3.3H 2 O), boehmite (Al 2 O 3.H 2 O) and diaspore, which has the same composition as boehmite but is denser and harder. Bauxite is usually classified according to its intended commercial application, e.g., metallurgical, cement, fertiliser, abrasive, chemical or refractory.

Bauxite Mineral. Bauxite is a mixture of minerals which contain, as well as impurities, different concentrations of hydrated aluminium oxides. Gibbsite (alumina trihydrate), boehmite, and diaspore (alumina monohydrates) are the main ore minerals. Bauxite is a high-aluminium-content rock. That is the main ore that aluminium is mined from.

Bauxite ore is the main source of aluminum and contains the aluminum minerals gibbsite, boehmite, and diaspore. Aluminum is used in the United States in packaging, transportation, and building. Because it is a mixture of minerals, bauxite itself is a rock, not a mineral. Bauxite is reddish-brown, white, tan, and tan-yellow.

Aluminum ore, also known as bauxite, is a naturally occurring mineral rock that contains aluminum in the form of aluminum oxide (Al2O3) mixed with various impurities. Bauxite is the primary source of aluminum, which is one of the most abundant elements in the Earth's crust, comprising about 8% by weight.
Minerals associated with the alumina hydrates in bauxites and laterites (ferruginous bauxites) include goethite and lepidocrocite, hematite, and the clay minerals kaolinite and halloysite. Bauxite is the main ore of aluminium and to be commercially exploited should contain more than 25–30% aluminium oxide.
