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.

2020-12-14 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,

BAUXITE deposits generally occur at or near the surface and are usually covered with shallow layer of overburden. The ore is almost invariably mined by open pit methods. The usual practice is to thoroughly strip and clear the overburden, after which the ore body is blasted to permit excavation by mechanical shovels. Some deposits contain highly siliceous clays and ferruginous materials distri ...
