Abstract: Methods and compositions for improving performance of flocculants in an industrial production process. Methods include pH triggered cross-linking reaction between a flocculating agent, such as dextran, and a composition comprising a boronic acid-containing polymer. The pH trigger can be provided by a fluid having a pH of 8 or more. The production process can be a Bayer Process and the fluid is caustic liquor or slurry in the fluid circuit of the Bayer, wherein the reaction time is reduced over conventional methods and the cross-linked dextran composition effectuates improved flocculation of the trihydrate particles.

Abstract: Improved sparge compositions for reverse froth flotation separation and uses thereof, and methods of reverse froth flotation are described. The sparge compositions comprise sulfonated polymeric modifiers which can act as dispersants and depressants, and the compositions are suitably used in the reverse froth flotation of particulate material containing ultrafine particles. For example, the compositions and methods can be used in the separation of iron oxide beneficiary from iron ores comprising silica, silicates, and the like.

Abstract: Improved sparge compositions for reverse froth flotation separation and uses thereof, and improved methods of reverse froth flotation are described. Described are sparge compositions comprising collectors and beneficiating agents, the collectors comprising sulfonated fatty acids and/or salts thereof, and the beneficiating agents comprising a hydroxy fatty acid composition. The sparge compositions are suitably used in the reverse froth flotation to separate phosphate beneficiary from ores comprising phosphate and dolomite, calcite, silicate, and/or other gangues. The disclosed compositions and methods exhibit improved separation of phosphate from such ores.

Abstract: Improved sparge compositions for froth flotation separation, methods of using them, and uses thereof are described. The compositions are suitably used in the froth flotation of particulate material containing ultrafine particles, and are well suited to the froth flotation separation of finely comminuted poor (low-grade) ores. The sparge compositions comprise functionalized silicone containing functionality that is tailored to the chemical nature of a beneficiary or a gangue in the ore. Sparging of the compositions effects improved recoveries and purities of beneficiaries. Sparge compositions and functionalized silicones suitable for the froth flotation of iron ores containing silica and/or silicate impurities are described. Sparge compositions and functionalized silicones suitable for the froth flotation of ores containing sulfur compounds such as sulfides are also disclosed.

Abstract: Methods of and systems for dispensing dust suppressant are provided. The methods comprise forming an aqueous dispersion stream by delivering a surfactant composition to an aqueous liquid stream. The aqueous dispersion stream is mixed to form a dust suppressant. The dust suppressant is dispensed to a surface at a pressure sufficient to provide coverage of the surface. Surface tension of the dust suppressant is measured via a tensiometer, and the measurement is relayed to a controller. The forming of the aqueous dispersion stream is adjusted according to the measured surface tension relayed to the controller. The systems are configured to carry out one or more of the provided methods.
