In order to reduce the moisture content after the final washing/thickening stage, vacuum drum filters have been typically used (Sparks et al., 2010, Borges et al., 2011). Filtration is performed, because dry cake disposal of bauxite residue requires filtration of the thickened residue, to obtain a cake with significantly reduced moisture

Red mud bauxite residue management is a critical issue for alumina refineries. For every single ton of Al 2 O 3 produced in the alumina refinery, as much as 2.5 tons of red mud residue must be handled. Depending on the bauxite ore grade and the geographic location of the alumina refinery, the amount of residue will vary.

Bauxite washing is a physical process that causes the disintegration and deagglomeration of the clay matrix, and bauxite is liberated from the clay (mainly rich in silica). Subsequently, separation occurs with the assistance of wet screening at a predetermined cut size. Three techniques were investigated in the laboratory: drum washing, water
