    摘要: The present invention provides techniques for recovering hydrocarbon fluids in a process flow, including recovering bitumen from a coarse tailings line. The apparatus includes a signal processor that responds to signaling containing information about the presence of a hydrocarbon fluid in a process flow; and determines corresponding signaling to control the diversion of the hydrocarbon fluid from the process flow remaining based on the signaling received. The hydrocarbon fluid may be bitumen, including bitumen flowing in a course tailings line. The signal processor receives the signaling from a velocity profile meter having sensors arranged around a circumference of a process pipe containing information about a fluid flow velocity at various levels or heights within the process pipe, including a wrap-around velocity profile meter having multiple sensing arrays located radially at a top position of 0°, a bottom position of 180°, and intermediate positions 45°, 90° and 135°.

    摘要: A copper/molybdenum separation processor is provided featuring a slurry/media mixture stage configured to receive a conditioned pulp containing hydrophobic molybdenite and hydrophilic copper, iron and other minerals that is conditioned with sodium hydrosulfide together with an engineered polymeric hydrophobic media, and provide a slurry/media mixture; and a slurry/media separation stage configured to receive the slurry/media mixture, and provide a slurry product having a copper concentrate and a polymerized hydrophobic media product having a molybdenum concentrate that are separately directed for further processing. The slurry/media mixture stage include a molybdenum loading stage configured to contact the conditioned pulp with the engineered polymeric hydrophobic media in an agitated reaction chamber, and load the hydrophobic molybdenite on the engineered polymeric hydrophobic media.

    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: 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.
