Vacuum drum filters which are the established and only available continuous filter technology for bauxite residue are limited in their dewatering capacity and produce thixotropic filter cakes with moisture contents of mc = 35 – 50 wt%. The high liquid content in the cakes and the poor wash results also.

20 Comment on washing drum for bauxite

Processing of Bauxite Ores

The low temperature digestor typically operates at 275 to 290 degrees F. Sodium Hydroxide (NaOH) is used to dissolve the alumina in the digestor. The Pregnant liquor is separated from the red mud tailings using a series of thickeners set up in counter current decantation arrangement, to continuously wash the alumina.

Bauxite - Wikipedia

Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium. Bauxite consists mostly of the aluminium minerals gibbsite (Al(OH)3), boehmite (γ-AlO(OH)) and diaspore (α-AlO(OH)), mixed with the two iron oxides goethite and haematite, the aluminium clay mineral kaolinite.
