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. In Fig. 1, we can see an example of a bauxite ore processing plant.

Associated with any bauxite source is some component of water, whose quantity depends on climate and geography, or the bauxite beneficiation processes. The bauxite moisture is normally a specified parameter, that the refinery utilizes in the design (or forecast) of their associated water balance.
Bauxite wet beneficiation requires large capital investments in a washing plant, tailings dams, power generation, water treatment, etc. and increased operating costs,
The Bayer Process, which is used by about 80 active plants worldwide, is the primary method of producing aluminum from bauxite. Bauxite ore is dissolved in sodium hydroxide, or lye, at a high temperature and pressure. Then, the alumina and bauxite ores are separated by washing out the waste (red muds or sands) from the alumina.
alumina production processes for low grade bauxite, such as Bauxite Flotation followed by the Bayer process and the Bayer-Sinter Series process, as well as the progress of research work into other alternative processes are reviewed in this paper.

bauxite can increase by 43.21% (2,659.44 tons/shift/day). In addition to increasing the quantity of production, the quality of bauxite is also improved by knowing the difference in the quality of bauxite, namely for Al2O3 0.822% and SiO2 0.035% and knowing the factors that influence it. Key words: production, washing process, washing plant
