Characterization and Beneficiation Studies of a Low Grade Bauxite Ore
The aluminium content of hematite is less than that of the goethite. The vanadium is found in boehmite and goethite compared to other alumina and iron bearing minerals. The negative correlation of TA with silica and iron oxide indicates that both these gangue constituents can be separated physically by suitable beneficiation techniques.
