Abstract: Pre-treatment techniques for pre-treating aqueous suspensions including fine solid particles include coarse debris removal prior to a chemical treatment operation. The suspension may include or be mining tailings, which may include mature fine tailings. The mining tailings may be generated from oil sands mining. The pre-treatment may include screening the tailings to remove coarse debris that would interfere with the tailings chemical treatment. The screening may be done by a screening device including a screen having and a collector body receiving the screened fluid. The screening device may include a tank screen with an inclined screen surface or an in-line screen. Several screening devices may be incorporated into a pre-treatment installation to treat parallel streams of tailings. The pre-treatment may be performed to enhance mixing of a flocculent into the screened tailings, followed by flocculation and dewatering of the tailings.

Abstract: A process and device to create access to low gravity solids (LGS) of about 2 to 20 microns for removal from a fluid material/LGS emulsion having the steps of: flowing the emulsion into high pressure tubing; separating the emulsion into at least two high pressure streams; forcing the emulsion through high pressure nozzles at a terminus of each of the at least two high pressure tubing streams at a speed in the range of about 10 ft/sec to 200 ft/sec or at a force in a range of about 10 to 100 PSI; and colliding the streams of emulsion exiting the high pressure nozzle within a pressure drop chamber, wherein the pressure drop is in a range of about 5% to 50% of the back pressure of the nozzles; wherein a cavitation effect is realized from a collision force of the high pressure streams within the pressure drop chamber.

Abstract: An apparatus separates a mixture of solid materials including mining materials into constituent parts. The separating apparatus comprises a substantially planar endless belt for receiving a slurry of the materials. A conveyor assembly rotates the endless belt upwardly at an incline from a feed end to a discharge end. Means are provided for vibrating the belt. An overhead spray array includes a plurality of nozzles for spraying fluid under pressure downwardly onto the slurry as the slurry travels on the conveyor belt for agitating the mixture of materials and influencing the constituents of the mixture to separate based on specific gravity. Material constituents having a higher specific gravity are urged along the conveyor to the discharge end for collection and the material constituents having lower specific gravity are urged off the sides of the conveyor belt under the action of the fluid sprays for collection.

Abstract: There is provided a system for treating a combination of a liquid and granular matter, which granular matter is larger than or equal to a minimum grain size and comprises two or more types of granular matter with different densities, wherein at least two of the different types of granular matter have densities being larger than the density of the liquid. The system comprises a stratification machine with a stratification or sorting chamber for holding the combination of liquid and granular matter, which stratification or sorting chamber has one or more side walls. The stratification machine also holds a movable plate arranged within the stratification or sorting chamber, where the moveable plate has sieve openings smaller than the minimum grain size of the granular matter to be treated to thereby maintain the granular matter above or on top of the movable plate. The stratification machine further holds a drive system for moving the movable plate in vertical upwards and downwards movements within the stratification or sorting chamber to thereby exercise or treat the granular matter within the liquid. There is also provided a method for treating the combination of a liquid and granular matter. The granular matter may include or consist of polymer granular matter.

Abstract: An apparatus for sorting particles in flowing suspension (120) comprises a first conduit (100) comprising a plurality of separate objects (104) orderly arranged in a form of a plurality of rows (106 to 110) inclined with respect to a direction (124) of a laminar flow of the suspension (120) including elongated particles (122) and flowing therethrough in a laminar manner, the elongated particles (122) of a botanical origin having a longitudinal dimension (L) larger than either of lateral and vertical dimensions (D). A shortest distance (L1) between directly adjacent objects (104) of a row (106 to 110) of the first conduit (100) is equal to or larger than the longitudinal dimension (L) of the elongated particles (122), and the objects (104) of the first conduit (100) are wider on a side receiving the laminar flow than on an opposite side which deviates the elongated particles (122) into separate paths in the laminar flow on the basis of their longitudinal dimension (L) for sorting them.
