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： The present invention provides new techniques related to magnetically controllable and/or steerable froth for use in separation processes of mineral-bearing ore and bitumen. Apparatus is provided featuring a processor configured to contain a fluidic medium having a material-of-interest and also having a surfactant with magnetic properties so as to cause the formation of a froth layer that contains at least some of the material-of-interest and is magnetically responsive; and a magnetic field generator configured to generate a magnetic field and provide non-mechanical mixing and steering/driving of the froth layer in the processor. The material-of-interest may be mineral-bearing ore particles or bitumen. The processor includes a flotation tank, a primary separation vessel (PSV), or a pipe, including a tailings pipeline. The pipe has a non-magnetic pipe section, and the magnetic field generator includes a magnetic coil arranged in relation to non-magnetic pipe section to generate the magnetic field and provide the non-mechanical mixing and steering/driving of the froth layer in the pipe.

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： Apparatus uses hydrophobic synthetic beads to recover mineral particles in a slurry. The synthetic beads and the slurry are mixed into a mixture for processing. The apparatus has an interaction vessel installed in a section of pipeline. The interaction vessel is made from a pipeline folded or coiled into a compact struction having a continuous flow path. The interaction vessel has an input to receive the mixture of slurry and synthetic beads. The folded or coiled structure is used to increase the residence time of the mixture in the flow path, allowing more time for the mineral particles in the slurry to attach to the surface of the synthetic bead, while maintaining a small footprint. The interaction vessel may be formed from a number of loops of pipe section. The interaction vessel may be formed from one or more folded structures.

摘要： A controller for controlling a slurry flowing from incoming piping and entering hydrocyclones arranged in a battery configuration, featuring a signal processor that receives signaling containing information about respective individual cyclone control signaling x(i) for each individual cyclone being evaluated and controlled, median control signaling {tilde over (x)} of all of the respective individual cyclone control signaling x(i), a scale factor Ai and a number N of the individual cyclones being evaluated and controlled; and determine/provides primary control signaling C containing information to control the slurry flowing from the incoming piping and entering the hydrocyclones arranged in the battery configuration by taking the median control signaling {tilde over (x)} and adding a correction factor, where the correction factor is determined by taking a sum of a respective difference of each of the respective individual cyclone control signaling x(i) and the median control signaling {tilde over (x)}, applying the scaling factor Ai to each respective difference, and normalizing the sum by the number N of the individual cyclones being evaluated and controlled, based upon the signaling received.

摘要： A system for sensing the volume and/or viscosity of a slurry (e.g., like concrete) contained in a rotating container or drum, having a sensor and a signal processor. The sensor is configured to attach inside a rotating container or drum having a known geometry, sense angular positions of the sensor and also sense associated entry and exit points when the sensor enters and exits the slurry, including concrete, contained in the rotating container or drum, and provide signaling containing information about the angular positions and the associated entry and exit points. The signal processor receives the signaling, and determines corresponding signaling containing information about a volumetric amount, or a viscosity, or both, of the slurry in the rotating container or drum, based upon the signaling received.

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.

摘要： A process of coating an open-cell foam substrate includes the steps of arranging two rollers separated by a gap; positioning the substrate above the gap; providing a coating material onto the substrate, feeding the substrate through the gap so as to achieve a layer of the coating material on the substrate, wherein the coating material is selected from the group consisting of a polysiloxane derivative, acrylic polymer, butyl rubber, natural rubber, nitriles, styrene block copolymers with ethylene, styrene block copolymers with propylene, styrene block copolymers with isoprene and polyvinyl ether and modifying the coating with tackifiers; plasticizers; crosslinking agents; chain transfer agents; chain extenders; adhesion promoters; aryl or alky copolymers; fluorinated copolymers; hexamethyldisilazane; and silica.

摘要： Apparatus uses engineered collection media to recover mineral particles in a slurry. The apparatus has a tumbler cell and a rotation device to rotate the tumbler cell. The tumbler cell has a container to hold a mixture of the engineered media and the slurry containing the mineral particles. The container is turned such that at least part of the mixture in the upper part of the container is caused to interact with at least part of the mixture in the lower part of the container. As such, the contact between the engineered media and the mineral particles is enhanced. The surfaces of the engineered media are functionalized with a chemical having molecules to attract the mineral particles to the surfaces so as to form mineral laden media. After the mineral laden media are discharged from the tumbler cell, the mineral particles can be separated from the engineered media by stripping.
