Sample dataBauxite is the ore of aluminium, refined into alumina and then smelted into metal. Guinea has the world's largest reserves and is the largest exporter by far, mostly to China's refineries, with exports near 200 Mt/yr and H1 2025 up 26 Mt year on year. Guinea is pushing miners to build local alumina refineries and revoked GAC's (EGA) Boké licence in August 2025. Ghana, Sierra Leone and Mozambique are smaller producers.

Minerals trade on formula prices: a published benchmark × metal content × payable percentage, less treatment charges and impurity penalties, settled on independent assay. Payment is typically by documentary letter of credit, with 90–95% provisional payment against shipping documents and the balance on final assay.

Guinea is the world's largest bauxite exporter (≈99.8 Mt in H1 2025, +26 Mt y/y), mainly to China. On 4 Aug 2025 Guinea revoked GAC's (EGA) Boké licence (11.9 Mtpa) and transferred it to state-owned Nimba Mining over refinery-building obligations. Metallurgical bauxite is specified by available Al2O3 and reactive SiO2 (Guinean ore typically ~45% Al2O3, low SiO2) and priced US$/dmt CIF China.
