Australia, Guinea, and Brazil are the leading exporters of bauxite, collectively accounting for over 70% of global exports in recent years; China is by far the largest importer, absorbing more than half of total international bauxite trade, followed by Canada and the United States. Global bauxite trade volumes have remained relatively stable since 2022, though regional shifts—including increased imports by China amid tightening domestic alumina refining capacity—have contributed to upward pressure on bauxite prices.
Bauxite is a naturally occurring, heterogeneous, clay-like sedimentary rock typically appearing as white, gray, reddish-brown, or yellowish material in solid, granular, or earthy form; it is odorless, non-volatile, and has no defined melting or boiling point due to its variable mineralogical composition. It is classified as a mixture of hydrated aluminum oxides—primarily gibbsite (Al(OH)₃), boehmite (γ-AlO(OH)), and diaspore (α-AlO(OH))—along with impurities such as iron oxides, silica, and titania. Bauxite serves almost exclusively as the principal raw material for aluminum production via the Bayer process, yielding alumina (Al₂O₃), which is then electrolytically reduced to metallic aluminum. Its downstream applications span aerospace, automotive, construction, packaging, and electrical industries, where aluminum and its alloys are employed in structural components, conductors, foils, and extrusions.
