  • Patent number: 10662505
    Abstract: Described herein are compositions and methods for preferentially separating mercury from a metal product where both are present in an ore leachate. The separation is accomplished by adding a precipitating agent and a coagulant to an ore leachate followed by separating a mercury-laden precipitate therefrom to collect the treated leachate. The treated leachate includes about 0 to 50% by weight of the mercury and about 90% to 100% by weight of the metal product present in the ore leachate. In embodiments, the method further includes adding a flocculant to the ore leachate prior to the separating of the mercury-laden precipitate.

  • Patent number: 8940175
    Abstract: Mass transfer sorption processes involve passage of a processed aqueous solution through a layer of granulated sorbent pre-filled with an organic liquid immiscible with either water or an aqueous solution under treatment. The apparatus for mass transfer of sorption processes is a vertical tank with inlet and outlet fittings loaded with a layer of sorbent disposed between the upper and the lower distribution and drainage systems. The industrial plant for separation of the components of aqueous solutions of inorganic substances includes the said apparatus and the apparatus for the separation of organic liquids from aqueous solutions. The latter has a casing with three chambers, the middle one of which is separated from the first outer one by a grid and from the other by a hydrophobic drainage layer. The emulsion to be separated is introduced into the middle chamber, and the separation results are derived from the outer chambers.

  • Patent number: 8912002
    Abstract: Provided is a method for high concentration cation exchange metathesis of divalent ions such as calcium with univalent ions such as sodium or potassium. Due to the difference between ionic valences between the exchanged ions, the provided process behavior is strongly dependent upon the selection of resin properties and to total solution normality. A combination of resin properties and solution normality is provided to achieve the cation exchange.

  • Patent number: 8894863
    Abstract: Systems and methods are presented for removing an ionic material from a fluid using a capture polymer that sequesters the ionic material and an anchor particle bearing a tethering polymer. The tethering polymer complexes with the capture polymer after the capture polymer has sequestered the ionic material, thereby affixing a complex of capture polymer and ionic material to the anchor particle to form a removable complex. The removable material can be segregated from the fluid via a removal system, thereby removing the ionic material from the fluid.

  • Publication number: 20140339172
    Abstract: An apparatus for collecting mineral particles in a slurry or the tailings is disclosed. The apparatus may take the form of a filter, a conveyor belt or an impeller to be used in a processor to collect mineral particles in the slurry, or in a tailings pond to collect mineral particles in the tailings. The filter, conveyor belt or impeller has a collection area made of or coated with a polymer or a polymer-coated material having a functional group, either anionic or cationic to attach to the mineral particles. Alternatively, the synthetic material has hydrophobic molecules to render the collection area hydrophobic. When the mineral particles in the slurry or tailings are combined with collector molecules, the mineral particles also become hydrophobic. The hydrophobic mineral particles are attracted to the hydrophobic collection area. The filter, conveyor belt and impeller may have a plurality of passage ways in order to increase the contacting surfaces.

  • Publication number: 20140326673
    Abstract: Nanoparticle-treated particle packs, such as sand beds, may effectively filter and purify liquids such as waste water. When tiny contaminant particles in waste water flow through the particle pack, the nanoparticles will capture and hold the tiny contaminant particles within the pack due to the nanoparticles' surface forces, including, but not necessarily limited to van der Waals and electrostatic forces. Coating agents such as alcohols, glycols, polyols, vegetable oil, and mineral oils may help apply the nanoparticles to the particle surfaces in the filter beds or packs.
