  • Emulsion compositions for priming a pavement surface
    Patent number: 11807759
    Abstract: Aqueous base- or acid-stabilized emulsions are provided for use on a pavement surface, and for use in an aqueous priming base emulsion that is used for priming a pavement surface. Any of the emulsions can be applied to a pavement surface to form a primed pavement surface, and then cured so that the pavement is available for use in preparing a pavement.
    Type: Grant
    Filed: September 9, 2020
    Date of Patent: November 7, 2023
    Assignee: Ecolab USA Inc.
    Inventors: Adam Meyers, Glenda Vale, Chenthamarakshan Nair, Vyacheslav Boyarskikh
  • Asphalt emulsion composition and method of treating a pavement surface
    Patent number: 11447637
    Abstract: Compositions and methods are provided for treating a pavement such as by microsurfacing or slurry sealing. The compositions contain iron chelants that are effective in reducing discoloration of the pavement surface.
    Type: Grant

    Assignee: Ecolab USA Inc.
    Inventors: Robert Gabel, Glenda Vale, Eric Bauch, Chenthamarkshan Nair, Adam Meyers
  • Functionalized silicones for froth flotation
    Patent number: 11014097
    Abstract: Improved sparge compositions for froth flotation separation, methods of using them, and uses thereof are described. The compositions are suitably used in the froth flotation of particulate material containing ultrafine particles, and are well suited to the froth flotation separation of finely comminuted poor (low-grade) ores. The sparge compositions comprise functionalized silicone containing functionality that is tailored to the chemical nature of a beneficiary or a gangue in the ore. Sparging of the compositions effects improved recoveries and purities of beneficiaries. Sparge compositions and functionalized silicones suitable for the froth flotation of iron ores containing silica and/or silicate impurities are described. Sparge compositions and functionalized silicones suitable for the froth flotation of ores containing sulfur compounds such as sulfides are also disclosed.
