摘要： 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 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; hydrophobizing 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.

摘要： 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.

摘要： An apparatus for removing mineral particles from loaded engineered collection media includes one or more solvents with sufficiently low surface tension. The engineered collection media are made of a synthetic material and have a surface coated with a hydrophobic material to provide a chemical bond between the mineral particles and the surface. The solvents together with a releasing mechanism are arranged to disrupt the chemical bond. Preferably, a surfactant or a nonionic surfactant is also added to the solvents.

摘要： 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.

摘要： 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.
