Modeling of Bauxite Ore Wet Milling for the Improvement …
The resulting sodium aluminate-rich liquor is separated by physical means, such as settling and filtration, from the insoluble residue, known as bauxite residue. Typically, depending on the type of bauxite used, 1 t of alumina results in the generation of residues varying from 0.3 t for high grade to 2.5 t for very low-grade bauxite [9, 10].
