Bauxit ist ein Aluminiumerz, das vorwiegend aus den Aluminiummineralen Gibbsit (Hydrargillit), Diaspor, ferner den Eisenoxiden Hämatit Fe2O3 und Goethit FeO(OH), dem Tonmineral Kaolinit und geringen Anteilen des Titanoxids Anatas TiO2 besteht. Ein sehr ähnliches Gestein, allerdings mit höherem Gehalt an Hämatit (also Eisen), ist Laterit.
