Abstract: An active chemistry capable of being combined with a carrier to produce a coating for fertilizer or other granular or compacted products, where the coating is capable of being applied at ambient temperature and is capable of reducing moisture adsorption and caking of the granular product. The active chemistry may be a functionalized polymer such as maleic anhydride/acid (from maleic anhydride), itaconic acid, diisobutylene, methacrylic acid, alkyl acrylates (i.e. butyl acrylate), hydroxyl ethyl methacrylate, 2-acrylamido-2-methyl propane sulfonic acid, 3-allyloxy-1,2-propanediol acrylic acid, acrylamide, or a combination thereof.

Abstract: A method of reducing dust formation and/or caking in fertilizer or other particulates. The method comprises coating the fertilizer or other particulate in a coating comprising vacuum tower asphalt extender (VTAE). The VTAE may be a non-distilled fraction of vacuum distillation of used automotive and/or industrial oil. The VTAE may not be asphalt or bitumen, although the coating may further comprise bitumen.

Abstract: A process of phosphate flotation comprising: pulping phosphate ore with water to about 55% to 75% solids to produce an ore slurry; conditioning the ore slurry with a new reagent scheme to produce a conditioned slurry; subjecting the conditioned slurry to flotation to produce an underflow and an overflow; and collecting the overflow as phosphate concentrate. The new reagent scheme may comprise a combination of fatty acid, fuel oil, and fatty acid soap, and may not comprise a pH modifier. The process may also work effectively at a lower percent solids than conventional reagent schemes.

Abstract: A magnesium suppressant/flocculant for use in separating dolomite from calcium phosphate. The magnesium suppressant/flocculant may be applied at a mine site prior to subjecting ore fractions to phosphate flotation or at a chemical plant after grinding.

Abstract: A reagent for phosphate flotation, the reagent comprising at least two fatty acids, an alcohol-based surfactant, and chemicals with sulfonate or sulfate groups. The reagent may not comprise fuel oil or diesel. The reagent may increase recovery of phosphate while improving the selectivity, and thus the grade, of the phosphate concentrate.

Abstract: Structured composite wood pellets comprising wood pellets with a coating at least partially covering the wood pellets, where the coating reduces the generation of dust/fines of the wood pellet upon impact and/or abrasion. The coating may comprise crude tall oil, distilled tall oil, tall oil pitch, tall oil fatty acids, tall oil heads, non-food use sustainable wax, or a combination thereof. The coating may be located at the surface and/or subsurface of the wood pellets rather than throughout, and may be applied at a rate of less than 1 wt. % of the wood pellets.

Abstract: A hydraulic fracturing and gravel packing proppant composite with protectant on the surface of the proppant and the composition matters of the protectant and proppant. The surface protectant reduces the generation of dust/fines from the proppant caused by abrasion and impingement during transportation and conveyance, particularly pneumatic transfer.

Abstract: An additive used in the production of wood pellets to increase throughput. The additive may be applied as a booster to wood prior to forming the wood into pellets. The booster may comprise 30% to 100% tall oil pitch and 70% to 0% tall oil head and may be applied at a rate of 0.01 to 2 wt. % of the wood.

Abstract: The invention is related to a flotation process using an improved collector to remove alkaline earth metal carbonate impurities from phosphate ores. The flotation feed may be conditioned with the improved carbonate collector at acidic pH, and subjected to a reverse flotation. The cell overflow may be collected as waste in which carbonate minerals dominate, and the cell underflow may be the phosphate concentrate. The collector may be a combination of chemicals, comprising: (1) any kind of fatty acids, either conventional fatty acid, saponified fatty acid, or modified fatty acid; (2) chemicals with sulfonate or sulfate groups, such as dodecylbenzene sulfonic acid (DDBSA) or its salt, sodium dodecyl sulfate (SDS), sodium lauryl sulfate (SLS), sodium coco sulfate (SCS), etc.; and (3) phosphorous-bearing chemicals, such as sodium tripolyphosphate (STPP), sodium hexametaphosphate (SFMP), trisodium phosphate (TSP), Tetrasodiumpyrophosphate (TSPP), etc.
