    摘要： Apparatus is provided featuring a first and second cells. The first cell receives an ore slurry having mineral particles of interest, receives unexpanded polymer microspheres comprising a surface having mineral collector chemistry attached thereto with molecules for attaching the mineral particles of interest, causes the unexpanded polymer microspheres to expand substantially in volume into expanded polymer microspheres having a substantially increased sphere surface area, and provides an expanded polymer microsphere foam layer comprising the expanded polymer microspheres with attached mineral particles of interest. The second cell receives the expanded polymer microsphere foam layer, and causes the expanded polymer microspheres to collapse substantially in volume into collapsed polymer microspheres having a substantially reduced sphere surface area that results in a mechanical shearing off of the attached mineral particles of interest. The second cell may also provide a mineral concentrate output having the mineral particles of interest.

    摘要： A synthetic bead for use in mineral separation is described. The synthetic bead has a surface made of a synthetic material such as polymer and the synthetic material is functionalized with molecules having a functional group for attaching mineral particles to the surface in a separation process. The synthetic beads can be placed in flotation cell containing a mixture of water, valuable material and unwanted material or in a pipeline where the mixture is transported from one location to another. The enriched synthetic beads carrying the mineral particles are separated from the unwanted materials in the mixture. The mineral particles are then released from the synthetic beads by means of low pH treatment, ultrasonic agitation, thermal or electromagnetic treatment.

    摘要： An apparatus for collecting mineral particles in a slurry or the tailings is disclosed, including a collection area or tank having one or more collection surfaces configured to contact with a mixture having water and valuable material, the valuable material having a plurality of mineral particles of interest; and a synthetic material provided at least on the one or more collection surfaces, the synthetic material having plurality of molecules with a siloxane functional group configured to attract the mineral particles of interest to the collection surfaces. The one or more collection surfaces includes a conveyor belt that is driven through the collection area or tank, through a release area or tank, back through the collection area or tank. The mixture includes a pulp slurry having ground ore with mineral particles of interest forming part thereof, including mineral particles of interest of about 500 microns or larger.

    摘要： An apparatus and method for collecting mineral particles in the tailings is disclosed. The apparatus may take the form of a filter, a conveyor belt, a collection plate or an impeller configured to contact with tailings of a flotation process, before and/or after the tailings are discharged into a pond. The filter, conveyor belt, collection plate or impeller has a collection area or surface made of, or coated with, a synthetic material having a functional group, e.g., having an ionizing bond to attract the mineral particles of interest. Alternatively, the synthetic material has hydrophobic molecules to render the collection area hydrophobic. When the mineral particles of interest in the tailings are combined with collector molecules, the mineral particles of interest may also become hydrophobic. The hydrophobic mineral particles of interest are attracted to the hydrophobic collection area or surface. The filter, conveyor belt, collection plate and impeller may have a plurality of passage ways or synthetic beads in order to increase the contacting surfaces.

    摘要： An apparatus for collecting mineral particles in a slurry or the tailings is disclosed. The apparatus may take the form of a filter, a conveyor belt or an impeller to be used in a processor to collect mineral particles in the slurry, or in a tailings pond to collect mineral particles in the tailings. The filter, conveyor belt or impeller has a collection area made of or coated with a synthetic material having a functional group, either anionic or cationic to attach to the mineral particles. Alternatively, the synthetic material has hydrophobic molecules to render the collection area hydrophobic. When the mineral particles in the slurry or tailings are combined with collector molecules, the mineral particles also become hydrophobic. The hydrophobic mineral particles are attracted to the hydrophobic collection area. The filter, conveyor belt and impeller may have a plurality of passage ways in order to increase the contacting surfaces.
