Even though Balaya-1 and Balaya-2 ores; undoubtedly from the same plateau; do not have any mineral constituent in common [38, 42], it was concluded from XRD analysis that mineralogical composition of all the Balaya Bauxite deposits are almost identical [38]; a deduction from the fact that Bauxite ores are irregularly scattered in the ore body ...

Abstract:Guinea with bauxite potential of about 40 billion tons is the largest aluminium ore exporter in the world today.During 2019, the country exported about 70 million tons of bauxite, which is likely to exceed 110 million tons by 2021. This may substantially change the present bauxite market and significantly affect other bauxite producing countries of the world.
