Bauxite Ore Rich

Bauxite -

Bauxite is an aluminum-rich sedimentary rock. It is the principal ore of aluminum. Aluminum in bauxite is hosted by aluminum hydroxide minerals, mostly gibbsite 4. The major impurities are iron oxides and hydroxides (which give reddish color to most bauxites) and clay minerals.

Extraction of scandium from scandium-rich material derived ...

Bauxite ore residue is an alkaline solid waste generated in the alumina production, which enriches approximately 98% of scandium in the bauxite ore (Nguyen et al., 2016, Klauber et al., 2011). The content of scandium in this residue varies from 0.0040 wt% to 0.0100 wt%, depending on the properties of raw bauxite ore and processing technologies.

Guinea is a West African country that is rich in bauxite. While the country lacks industries to transform the resource-rich rock into a precious metal, new laws are being enacted to protect the country’s resources and share the profits with the people.

Mineralogical and geochemical studies of boron-rich ...

Available data indicate that boron-rich bauxite ores are rare in the world (Mordberg, 1996). Franceschelli et al. (1998) reported a boron-rich bauxite deposit in Italy but attributed the boron enrichment to hydrothermal overprinting. Lack of boron enrichment in other important bauxite deposits in the world may be due to lack of boron-rich protoliths.
