Each type of bauxite ore presents its own challenges in terms of mineral processing and beneficiation for the generation of alumina [7,8]. Normally, the beneficiation or treatment of bauxite is limited to crushing, sieving, washing, and drying of the crude ore [3]. Flotation has been employed for the upgrading of certain low-grade bauxite ores,
