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, however it has not proven highly selective at rejecting kaolinite, a major source of reactive silica especially in trihydrate bauxites [9].

Iron ore with low Fe content and high Al:Si ratio can not be used directly in any of the processes. This has been mainly due to the presence of high levels of impurities such as silica and alumina in the raw materials. Therefore, research on beneficiation and utilization of low grade iron ore to produce quality raw material is highly essential.

During the Bayer process for alumina production, the molecular formula of the bauxite residue is approximately equivalent to Na 2 O·Al 2 O 3 ·1.7SiO 2 ·nH 2 O. This means that 1 kg of SiO 2 in bauxite will produce 1 kg of Al 2 O 3 and 0.608 kg of Na 2 O in bauxite residue. Thus, the extraction efficiency of alumina is low when processing low-grade bauxite.

Bauxite is the main raw material in primary aluminum production and its reactive silica content and mass ratio of Al 2 O 3 to SiO 2 (A/S) has a critical role in the economic viability of Bayer process. As a major source of the reactive silica, clay impurities should be removed from the ore as much as possible by a beneficiation method such as froth flotation before the Bayer processing.

12%Abstract. Bauxite is the major alumina (Al 2 O 3) bearing ore used in the aluminum manufacturing industries.The bauxite containing less than 50% Al 2 O 3 is called low-grade bauxite ore which is commonly used for the alumina-based abrasives and refractories productions. The alumina-silica and alumina-ferrite complexes are the foremost impurities present in the low-grade bauxite.
