Guinea’s bauxite mining development CRU

Aug 19, 2020 By 2040, the capacity gap was expected to increase to 83 Mt, demonstrating a long-term need for investment in bauxite mining capacity. In the early 2020s, however, we expected a short-term global surplus of bauxite as the result of mine ramp-ups in Guinea (including our client’s project), in Australia to a lesser degree and in China.

Bauxite Wikipedia

Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium and gallium.Bauxite consists mostly of the aluminium minerals gibbsite (Al(OH) 3), boehmite (γ-AlO(OH)) and diaspore (α-AlO(OH)), mixed with the two iron oxides goethite (FeO(OH)) and haematite (Fe 2 O 3), the aluminium clay mineral kaolinite (Al 2 Si 2 O 5 (OH)) and small
