Investigation of Flotation Behaviors of Refractory High

High content of silica results in high soda consumption, which limits the use of highsilica bauxite in the production of Bayer alumina In this work,the main flotation parameters of high silica bauxite (A/S 50) including particle size, pulp pH, collector dosage and dispersant dosage were studiedFlotation, on the other hand, is used to reduce the content of impurities in lowgrade iron ores 12,5 Iron ores can be concentrated either by direct anionic flotation of iron oxides or reverse cationic flotation of silica, however reverse cationic flotation remains the most popular flotation route used inSun Flotation Of High Silica Bauxite The reactive silica content not only increases the volume of red mud, but also consumes caustic soda reagent and reduces the yield of Al2O3 recovered from the bauxite Therefore, there is both an economic and environmental argument to be made for improving the quality of bauxite prior to refiningBauxite Beneficiation Flotation Silica Iron

(PDF) Reduction of Reactive Silica from Bauxite

Some bauxites have high chemical contents of reactive silica and other impurities, being considered marginal bauxites Nowadays, these bauxites are not used for the However, reverse flotation (floating reactive silica impurities, but depressing bauxite minerals) has certain advantages over direct flotation such as high efficiency, lower cost, ease of dewatering (Cao et al, 2008, Hu et al, 2003, Xia et al, 2009a, Zhong et al, 2008, Chen et al, 2005, Zhao et al, 2010)Characterization and flotation of lowgrade boehmitic The preparation of bauxite caused an increase in the alumina/silica mass ratio from 730 to 1105 Subsequently, laboratory scale flotation tests were conducted to verify the reproducibility of the results indicated in the microflotation stage Laboratory scale flotation tests were done in a Denver machine using a 900 mL cellKaolinite removal from bauxite by flotation

The Influence of Backwater Al3+ on Diaspore Bauxite

The effect of Al3+ in backwater on the flotation of diaspore bauxite was investigated by microflotation tests and the underlying mechanisms were investigated by inductively coupled plasma (ICP) measurement, zeta potential measurements, solution chemistry analyses, and synchrotron near edge Xray absorption fine structure (NEXAFS) analyses The ICP measurement results show the Separation of silica from bauxite via froth flotation Mar 01, 2009 Bittencourt, 1989, Bittencourt et al, 1990, aiming to obtain a gibbsite concentrate that could be used as raw material for the production of alumina refractories, tried direct flotation of the bauxite minerals from a Brazilian ore sample, composed basically of gibbsite (50%), kaolinite (15%) and quartz (35%)flotation of silica from bauxite oreSeparation of silica from bauxite via froth flotation Bittencourt, 1989, Bittencourt et al, 1990, aiming to obtain a gibbsite concentrate that could be used as raw material for the production of alumina refractories, tried direct flotation of the bauxite minerals from a Brazilian ore sample, composed basically of gibbsite (50%), kaolinite (15%) and quartz (35%) This flotation was carried out bauxite mining and flotation cell plant
