  • Patent number: 10427166
    Abstract: A transportable modular system for enhanced minerals recovery from tailings lines and deposits, features two transportable mineral recovery modules (TMRM), each TMRM for transporting as a truck mounted module to a remote site as an independently-operable mineral recovery module, each TMRM to couple to another TMRM on-site at the remote site and used together to provide enhanced minerals recovery. One TMRM having a central engineered polymer mineral recovery module that receives tailings fluid having a mineral particle of interest, processes the tailings fluid using an engineered polymer configuration, and provides recovered mineral processing fluids having the mineral particle of interest and a tailings disposal fluid. One other TMRM is selected from a group of TMRMs that includes another central engineered polymer mineral recovery module, a tailings fluid management module, an additive/chemical treatment polymer management module, a tailings disposal module and a recovery mineral processing module.

  • Publication number: 20190291121
    Abstract: 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.

  • Publication number: 20190261897
    Abstract: An apparatus for inspecting a biological tissue uses a pH-sensitive coating material to determine whether the tissue is normal or cancerous. The coating material is placed in contact with the tissue to be excited by an excitation light. The coating material is arranged to provide a response signal indicative of the pH value of the tissue. Using a fiber bundle having a plurality of optical fibers forming a linear array or a two-dimensional array adjacent the coating material, the imaging of localized surface pH in the biological tissue can be achieved using the response signal through each of the optical fibers. The fiber bundle can be arranged as a probe to examine the tissue for providing direct mapping of the tumor margin via a display, so that a surgeon can inspect the tissue in real-time.

  • Publication number: 20190232301
    Abstract: A flotation tank has an input to receive a slurry from a pipeline section. The slurry contains finer mineral particles and coarser mineral particles. The pipeline section has one or more loops or coiled sections arranged to perform partial centrifugal separation on the finer and coarser mineral particles. As the mineral particles are moved tangentially into the lower part of the flotation tank, the coarser mineral particles tend to be near the tank wall while the finer mineral particles tend to move into the central part of the tank. Air bubbles or lightweight synthetic bubbles are used to collect and lift the finer mineral particles to the upper part of the tank. The coarser mineral particles are recovered by using collection surfaces coated with a hydrophobic material.

  • Patent number: 10245597
    Abstract: 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.

  • Patent number: 9943860
    Abstract: 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.
