Bauxite transport and traceability: Why tracking the cargo back to the mine is difficult

Bauxite is the starting material for alumina refining and primary aluminium production, but its route from mine to refinery is rarely as simple as a labelled shipment moving from one country to another. Unlike fabricated metal products, bauxite is usually traded as a loose bulk mineral. It is loaded into stockpiles, trucks, rail wagons, barges and bulk carriers, often passing through multiple handling points before reaching an alumina refinery. This logistics model keeps transport costs low for a high-volume commodity, but it also makes mine-level origin difficult to establish. The key question for traders, refiners and downstream buyers is therefore not only about where a cargo was loaded but where the ore was actually mined and whether that origin can be traced and documented along the...
