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: The invention is directed towards methods and compositions for preventing dusting problems in mineral supplement. The method involves treating the mineral supplement or a dust releasing material with a composition comprising polymerized organic acid.

Abstract: The invention provides methods and compositions for blends of glycerin and polyvinyl acetate emulsions which effectively decrease the dust forming tendency of particulate materials such as mineral fertilizer(s). These blends also reduce the caking tendency of mineral fertilizer(s), helping to maintain a free flowing material. Formulations based on these components, possibly including other additives, may also be useful for dust control and/or anticaking on other particulate materials including fertilizers, ores, coal, grain, etc.

Abstract: A method for minimizing the addition of water to a phosphoric acid production process is described. The method uses phosphoric acid to make down a flocculant that is added to the process in order to promote filtration or clarification of crude phosphoric acid. Preferably, the phosphoric acid is a crude, clarified phosphoric acid that is recycled from the phosphoric acid production process itself.

Abstract: The invention is directed towards methods and compositions for simultaneously preventing caking and dusting problems in mineral supplement. The method involves treating the mineral supplement with a composition comprising sorbitan N-esters (of fatty acids), mineral oil, and microcrystalline wax. This invention allows a user to solve two different problems each of which is often made worse by the cure for the other with a single composition. Best of all the single composition requiring minimal heating for application.
