Silicon is the main impurity in high-silica bauxite [1], [2], [3] and causes scaling on plant surfaces while affecting the quality of alumina during alumina production, using alkaline methods such as the conventional Bayer process [4], [5], [6].With the increasing demand for alumina refineries, the utilization of low-grade high-silica bauxite has attracted substantial …

decline of high-grade bauxite resources. Hence, it is necessary to evolve new methodologies for manufacturing aluminium metal from low-grade bauxite, aiming to reduce caustic and energy consumption and utilize the available low-grade bauxite deposits. Bauxite production is steadily rising to meet the increasing demand.

However, its application is restricted by the necessity for fine grinding (80%-90% below 0.074 mm) and by the unknown effects of flotation reagents on the Bayer process. Therefore, due to their low operating and investment costs, gravity methods may be a suitable way to treat low-grade bauxite prior to introducing it to the Bayer process [11-15].
