Bauxite is a sedimentary rock that is the main ore of aluminum. Bauxite varies in composition, as does any rock, but the main components are minerals of aluminum oxide and aluminum hydroxide. Bauxite may also contain amounts of iron, clay, silt and silica. Bauxite is the result of the leaching of minerals from tropical soils leaving a hardened clay-like material that is high in the above minerals, which resist leaching. In addition to being the primary source of aluminum, some bauxite is also used in the manufacture of abrasives.
