摘要： 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 phosphate beneficiary from ores comprising phosphates, dolomite, calcite, clay, silica, silicates, carbonates, and mixtures thereof.

摘要： The invention provides methods and compositions for green compositions and technologies. In an embodiment, the present invention provides a method of separating a first material from a second material. For example, the method can comprise mixing the first material and the second material in a slurry with a beneficiation composition. The beneficiation composition can comprise one or more glyceride and fatty acid mixtures extracted from a fuel ethanol process. Air bubbles can be provided in the slurry to form bubble-particle aggregates with the first material and the bubble-particle aggregates can be allowed to be separated from the second material.

摘要： 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.

摘要： 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.

摘要： The invention provides methods and compositions for improving a froth flotation type separation. The method uses a thickener to improve the effectiveness of an emulsifier. The improvement allows for low dosages of emulsifier to work well so the emulsifier does not cancel out the effectiveness of other additives in the slurry such as collectors, frothing agents, regulators, depressors, deactivators, and/or activators.
