  • BAUXITE GRINDING AIDS AND METHODS OF USE
    Publication number: 20190084837
    Abstract: Bauxite grinding compositions that can significantly reduce the viscosity of bauxite slurry, which allow alumina refinery plants to increase throughput of bauxite grinding or pre-desilication. Described are processes to improve the grinding of a bauxite containing slurry in a Bayer process comprising: adding an effective amount of a bauxite grinding composition to the bauxite containing slurry before or during the grinding step or pre-desilication step, wherein the bauxite grinding composition comprises dextran, maltitol or a co-polymer.

  • OIL-FREE CRYSTAL GROWTH MODIFIERS FOR ALUMINA RECOVERY
    Publication number: 20170225962
    Abstract: Disclosed herein is a method of producing alumina trihydrate crystals from an alumina trihydrate recovery process stream wherein an aqueous emulsion comprising an alkyl or alkenyl succinic anhydride is added to the alumina trihydrate recovery process stream, wherein the aqueous emulsion is substantially free of mineral oils. The method provides a decrease in percentage of alumina trihydrate crystals having a volume average diameter of less than about 45 micrometers compared to the percentage of alumina trihydrate crystals produced in the absence of the aqueous emulsion of an alkyl or alkenyl succinic anhydride.

  • Polymer blends for dewatering
    Patent number: 6117938
    Abstract: The invention provides blends of high molecular weight, water-soluble cationic structured polymers with high molecular weight, water-soluble, cationic polymers which either are linear or which have a lower degree of structure. The blends are useful for dewatering dispersions of suspended solids, achieving good dewatering rates at relatively low dosage levels.
