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.

Processes for the separation of ores

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.

Guanidine-based polymers for separation processes

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.

Liquid compositions containing urease inhibitors and glycol alkyl ethers and methods of making a use thereof

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.

Dedusting compositions and methods for making and using same

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.

Pitch emulsions

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.

Materials and process for enhancing selective separations

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.

Method for inhibiting ice formation and accumulation

Thermosetting adhesives for use in e.g., particleboard or fiberboard, wherein the adhesives comprise a resin having azetidinium functional groups, can provide fast tack-building and curing, as well as ultimately excellent bonding characteristics. Preferably, the azetidinium-functional resin is formed from the reaction product of a polyamidoamine and epichlorohydrin.

Thermosetting adhesives comprising a resin having azetidinium functional groups

A non-aqueous coating composition of very low volatility (i.e., low-VOC) that can be cured in a short period of time under an ambient temperature condition without the use of solvents consisting essentially of a mixture or blend of three components: (1) a complex ester made by reacting a monomeric monobasic fatty acid, a mixture of diacids and a polyol;(2) a drying oil (i.e., primarily an unsaturated fatty acid triglyceride); and (3) an unsaturated monomer of low volatility and its use for producing a coated substrate and especially a wood composite material substrate having a cured seal coat.

Non-aqueous coating formulation of low volatility

A coated aggregate material for enhancing the extended delivery of nitrogen needed for plant development and growth, the coated aggregate material having a slow release (extended-release) nitrogen coating of a particulate UF polymer adhered to the aggregate material with an adhesive binder.

Slow release nitrogen coating

A melamine-urea-formaldehyde resin modified with a cyclic urea prepolymer and sodium metabisulfite. Products prepared with the binder include wood composites such as particleboard and medium density fiberboard.

Melamine-urea-formaldehyde resins modified with cyclic urea prepolymer and sodium metabisulfite

A melamine-containing resin modified with a cyclic urea prepolymer comprising urea, formaldehyde and ammonia or a primary amine. The prepolymer-modified melamine-containing resin provides useful binders alone, or when combined or coreacted with other resins. Products prepared with the binder include wood composites such as particleboard and medium density fiberboard.

Cyclic urea-formaldehyde prepolymer-modified melamine-containing resins, and use in binders for cellulosic-based composites

The preparation of composites using epoxy-functional silicones as additives to phenolic resole resins.
