Bauxite. Bauxite is an ore that mainly contains either Gibbsite (alumina trihydrate, Al 2 O 3.3H 2 O) or Boehmite (a monohydrate of alumina, Al 2 O 3.H 2 O). Raw bauxite may have other impurities such as ferrous oxide, silica, and titania. Refractory grade bauxite has low iron but high alumina content.
