20090301972 | MATERIALS AND PROCESS FOR ENHANCING SELECTIVE SEPARATIONS - Use of a Maillard reaction product as an adjuvant in a variety of applications including solid-liquid separations, corrosion inhibition, emulsification, dust suppression, slow release fertilization, viscosity modification and others and especially as a depressant or collector in separation processes, including the selective separation of solids and/or ionic species from aqueous media, such as in the process of froth flotation. | 12-10-2009 |
20100117023 | METHOD FOR INHIBITING ICE FORMATION AND ACCUMULATION - The present invention relates to a method for inhibiting the formation or accumulation of ice on a solid surface and for reducing the salt out temperatures. | 05-13-2010 |
20100331484 | GUANIDINE-BASED POLYMERS FOR SEPARATION PROCESSES - Cationic polymers and methods for using the same are provided. The method can include contacting an aqueous medium with a cationic polymer. The cationic polymer can include a polymer formed by reacting an aldehyde, and optionally an aldehyde-reactive compound, in the presence of a sufficient amount of guanidine to provide the polymer with a net cationic charge. | 12-30-2010 |
20110049417 | DEDUSTING COMPOSITIONS AND METHODS FOR MAKING AND USING SAME - Compositions for reducing the formation of dust and methods for making and using same are provided. The composition can include an emulsion comprising one or more pitches, one or more fatty acids, one or more rosins, or any combination thereof. The composition can also include one or more film forming polymers, one or more oils, or a combination thereof. | 03-03-2011 |
20110168943 | Pitch Emulsions - An emulsion of pitch in water preferably characterized by having a lower level of tack on drying by virtue of using as the emulsifying agent a fatty acid, a chemically modified fatty acid, a rosin acid, a chemically modified rosin acid, or combinations thereof, especially a tall oil fatty acid, or a chemically modified tall oil fatty acid, where the pitch emulsion is useful for reducing the development of fugitive dust in a dust-forming material. | 07-14-2011 |
20120006222 | Method for Inhibiting Ice Formation and Accumulation - The present invention relates to a method for inhibiting the formation or accumulation of ice on a solid surface and for reducing the salt out temperatures. | 01-12-2012 |
20140047883 | Liquid Compositions Containing Urease Inhibitors and Glycol Alkyl Ethers and Methods of Making a Use Thereof - The present invention provides improved solvent systems for the preparation of liquid formulations of urease or nitrification inhibitors, specifically NBPT, comprising alkylene glycol alkyl ethers. The solvent systems provided good solubility of the urease inhibitor as well as at least one of improved stability, lower flammability, lower toxicity, improved cold temperature storage, improved handling, improved adsorption onto and/or solubility with solid media such as UFP or urea. Methods of making and using the compositions are also provided. | 02-20-2014 |

20140034871 | DEDUSTING COMPOSITIONS AND METHODS FOR MAKING AND USING SAME - Compositions for reducing the formation of dust and methods for making and using same are provided. The composition can include an emulsion comprising one or more pitches, one or more fatty acids, one or more rosins, or any combination thereof. The composition can also include one or more film forming polymers, one or more oils, or a combination thereof. | 02-06-2014 |
20140110621 | PROCESSES FOR THE SEPARATION OF ORES - Methods for purifying one or more value materials are provided. The method can include contacting an aqueous mixture comprising a value material and a contaminant with a dispersant and a depressant to produce a treated mixture. A weight ratio of the dispersant to the depressant can be from about 1:1 to about 30:1. The method can also include recovering a purified product comprising the value material from the treated mixture. The purified product can have a reduced concentration of the contaminant relative to the aqueous slurry. | 04-24-2014 |
