    The more is the silica, higher is the soda consumption which increases the cost of alumina production. Physical beneficiation techniques are employed to reduce the reactive silica content of bauxite. Based on several investigations it has been made possible to remove 30 of silica with 92 recovery depending on the characteristics of the ore.

    The bauxite ore with high alumina content and a high mass ratio of alumina to silica (A/S ratio) is preferred in the alumina industry. The free silica leads to the formation of Bayer sodalite with important losses of sodium hydroxide and alumina in the muds (near to 30%) [6]. The production process of Bayer alumina is shown in Figure 2. In the Bayer process, bauxite is leached with a hot ...
