  • Method of separating mercury from an ore leachate
    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.

  • Compositions for enhanced oil recovery
    Patent number: 10647907
    Abstract: Compositions and methods for increasing recovery, or flowback, of hydrocarbon compounds from hydrocarbon-containing subterranean reservoirs. The compositions include a dialkyl dimethyl ammonium surfactant, an amphoteric surfactant, and a solvent. The concentrated compositions are storage stable and easily diluted with a water source such as produced water to form injectates suitable for injecting into one or more hydrocarbon-bearing subterranean reservoirs. The injectates convert oil-wet rocks to water-wet but do not cause formation of emulsions with hydrocarbon compounds within the subterranean environment. Injection of the injectates into a reservoir results in an increase in the yield of hydrocarbons recovered, in particular from low permeability, low porosity reservoirs such as those formed by or encountered in hydraulic fracturing and/or in certain geographic locations.
