12.11.2014· Clay impurities associated with bauxite negatively affect the Bayer process for alumina production. These impurities should be removed as far as possible by a beneficiation technique before the ore is used as feed for the Bayer process. In this current investigation, bauxite washing was conducted in the laboratory. Bauxite washing is a physical process that causes the disintegration and

Conditions within the digester (caustic concentration, temperature and pressure) are set according to the properties of the bauxite ore. Ores with a high gibbsite content can be processed at 140°C, while böhmitic bauxites require temperatures between 200 and 280°C. The pressure is not important for the process as such, but is defined by the steam saturation pressure of the process. At 240
Extraction Process of Aluminium from Bauxite Ore. Previous Next View Larger Image and these products flow to the fine-red-mud washing thickeners mentioned above. The sodium aluminate liquor which overflows the primary thickener is clarified by filtering and the filtrate is decomposed to aluminum hydroxide which is calcined to produce the final alumina product. In the conventional Bayer
Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium and gallium.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 (FeO(OH)) and haematite (Fe 2 O 3), the aluminium clay mineral kaolinite (Al 2 Si 2 O 5 (OH)) and small
