  • Separation of silica from bauxite via froth flotation

    Liu et al., 2007, Wang et al., 2004, Xu et al., 2004 related the viability of increasing the Al 2 O 3 /SiO 2 ratio of Chinese diasporic bauxites by removing quartz silica through a flotation process. These papers constitute the only literature found about reverse bauxite flotation, for producing gibbsitic or diasporic bauxite concentrates. 3

    Deposits of bauxite ores near aluminum smelters often possess an excessively high percentage of silica. Development of such high-silica ores would be beneficial to alumina producers.

  • Separation of silica from bauxite via froth flotation

    This paper reports an innovative development: concentrating gibbsite via reverse froth flotation in order to obtain a metallurgical-grade bauxite concentrate. Tailings from an industrial plant have undergone attrition scrubbing and desliming; the quartz silica contained in the tailings has undergone flotation.

    However, a high-grade bauxite contains up to 60% Al2O3, and many operating bauxite deposits are well below this, occasionally as low as 30-40% Al2O3. Because the desired product is a high purity Al2O3, the remaining oxides in the bauxite (Fe2O3, SiO2, TiO2, Organic material) are separated from the Al2O3 and rejected as alumina refinery resides

  • Investigation of Flotation Behaviors of Refractory High

    High content of silica results in high soda consumption, which limits the use of high-silica bauxite in the production of Bayer alumina. In this work,the main flotation parameters of high silica bauxite (A/S 5.0) including particle size, pulp pH, collector dosage and dispersant dosage were studied.
