The main objective of bauxite processing is to adjust the granulometry, increase the usable alumina content, and reduce the reactive silica content. As the ore fines concentrate the source of reactive silica, usually clay minerals, the bauxite beneficiation processes consist of washing and classifying the ore, to discard the finer fractions.

The results suggested notable beneficiation efficiency of coarse sized bauxite via dry fluidized bed separator. Moreover, the separation efficiency of coarse sized bauxite gradually declined with decreasing size fraction, which indicated that the dry-based fluidized bed separator had a low limit size of feeding for ore separation.

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,
