  • Publication number: 20230278044
    Abstract: A substrate for use in an aqueous slurry has a polymeric coating to provide a compliant and sticky surface. The polymer coating has a chemical to render the surface hydrophobic so as to attract hydrophobic or hydrophobized mineral particles in the slurry. The surface has a surface roughness structure in the nano-scale to micro-scale range. The substrate can take the form of a conveyor belt, a bead, a mesh, an impeller, a filter or a flat surface. The substrate can also be an open-cell foam. The polymeric coating can be modified with tackifiers; plasticizers; crosslinking agents; chain transfer agents; chain extenders; adhesion promoters; aryl or alky copolymers; fluorinated copolymers and/or additives; hydrophobicizing agents such as hexamethyldisilazane; inorganic particles such as silica, hydrophobic silica, and/or fumed hydrophobic silica; MQ resin; and/or other additives to control and modify the properties of the polymer.

  • Publication number: 20230053562
    Abstract: A composite medium for collecting mineral particles in an aqueous slurry has a polymer substrate deposited or penetrated with an inorganic material and further coated with a hydrophobic material. The hydrophobic material can be a hydrophobic silane or a hydrophobic polymer such as polysiloxane. Alternatively, the inorganic material deposited substrate is first reacted with a reactive silane and then coated with a hydrophobic polymer. The polymer substrate can be in the form of a spherical bead, a small cube, a filter or a conveyor.

  • Publication number: 20210379603
    Abstract: An engineered collection medium for use in mineral separation is described. The engineered collection medium has a solid phase body configured with a three-dimensional open-cell structure like foam or sponge to provide collection surfaces. The three-dimensional surface structure is made of a hydrophobic material which is a reaction product of isocyanate and polyol promotes the attraction of mineral particles to the collection surfaces as a hydrophobic foam. The hydrophobic foam can be in the form of a cube, sphere, or sheet and can be used in a filter or conveyor belt in a processor.

  • Patent number: 5344373
    Abstract: A device for pool use that holds a swimmer stationary. A base strap attaches to a stationary poolside object. Two ankle straps are directly connected to said base strap by two elastic cords, respectively. The ankle straps are attached to a swimmer's ankles. The swimmer can then engage in continuous swimming exercise in a small pool as the stationary swimming apparatus holds the swimmer stationary with respect to the poolside object.
