  • Separation of silica from bauxite via froth flotation

    01/03/2009· 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. Starch was used as a depressant, and ether-amine as the cationic collector. Optimum pH is

    Flotation is primary used for mineral extraction from lithium ores. In this process, lithium ores are concentrated with respect to lithium oxide from 1–3% Li 2 O to 4–6% Li 2 O through heavy medium separation using dense nonaqueous liquids in a froth flotation process. Silicate ores are most widely processed using the flotation method, those products are subsequently chemically cleaned by an

  • Relevant Problems of Quartz Extraction Technology

    Quartz sand (silica sand) is mainly derived from quartzite and vein quartz, which is accompanied by feldspar, mica and clay minerals, while vein quartz is accompanied by feldspar, mica, cuttings, heavy minerals, clay minerals and so on. Although the structure formed by quartzite and vein quartz is different, the composition is similar, so the selection of the mineral processing technology is
