Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world''s main source of aluminium and consists mostly of the aluminium minerals gibbsite (Al(OH) 3), boehmite (γAlO(OH)) and diaspore (αAlO(OH)), mixed with the two iron oxides goethite (FeO(OH)) and haematite (Fe 2 O 3), the aluminium clay mineral kaolinite (Al 2 Si 2 O 5 (OH)) and small ...
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. Finally, hydrated alumina is crystallized and calcinated (dried in a .

Feb 15, 2019· 1. Introduction. Bauxite residue, a byproduct of alumina production through the Bayer process, exerts a substantial impact on environments by contaminating water and soil due to alkali liquid leakage, polluting the air with bauxite residue dust, and altering land occupation [1,2].Bauxite residue is a type of solid waste with high alkalinity and a high heavy metal content [], which is a ...
The bauxite residue sinks to the bottom of the settling tanks, then is transferred to the washing tanks, where it undergoes a series of washing stages to recover the caustic soda (which is reused in the digestion process). Further separation of the pregnant liquor from the bauxite residue is performed utilising a series of security filters.
