摘要： The present invention provides a method and an apparatus for separating a mixture that are capable of separating a mixture containing a plurality types of particles, using a countercurrent classification technique, even when there is little difference in density and particle diameter depending on the types of particles. In the present invention, a mixture containing first particles and second particles is separated using a separation tube 13 having the inverted-conical or pyramidal shape or a substantially inverted-conical or pyramidal shape. The first particles and the second particles are made of substances having different magnetic susceptibilities. A fluid is caused to flow upward through the separation tube 13, and the flow of the fluid is used to introduce the mixture into the separation tube 13. The first particles and the second particles are held in the separation tube 13 in a mixed state. A gradient magnetic field is applied to a region inside the separation tube 13 using magnetic field generation means 23, in the state where the first particles and the second particles are held in the separation tube 13. The magnetic field gradient of the gradient magnetic field has a vertical component.

摘要： A housing adapted to receive a flow of slurry has a central section, an upper section, and a lower section. A clean water introduction assembly has a horizontal manifold, a plurality of horizontal apertured pipes and a plurality of vertical water lines. A valve assembly has an upper valve and a lower valve. The upper valve is normally open. The lower valve is normally closed to feed clean water from the manifold through the water lines and out of the apertured pipes into the housing. In this manner water entering the housing will cause a hindered settling. The valve assembly is also operable in a back flow mode with the upper valve being closed and the lower valve being opened. In this manner water from the housing will flow from the apertured pipes. In this manner clogs in the holes of the apertured pipe are cleared. A coupling assembly is provided.

摘要： A process and apparatus for the recovery of heavy metals from a heavy metal-contaminated material wherein the heavy metal, or particles containing the heavy metal, are separated from the material by a hydraulic mineral separator. The process and apparatus may be used, for example, in removing or recovering of mercury from a mercury-contaminated soil, caustic sludge, or similar material. The process provides a ready method for removal of mercury from mercury-contaminated materials or, more generally, heavy metals from heavy metal contaminated soils which process can allow recovery of the mercury or heavy metal for re-use. The apparatus allows for continuous operation of the mineral separator and automates various functions of the separator allowing for improved control of the process.

摘要： A process for concentrating mica in a mixture of sand and mica is disclosed, which comprises introducing the feed mixture of sand and mica into an upper part of a density separating vessel in which is provided a rising current of an aqueous medium, the velocity of the current being uniform or substantially uniform over a horizontal cross-section of the vessel and being such that all but the least buoyant particles of the mixture are held in suspension as a bed which is gently displaced upwards in the vessel by incoming feed mixture; and passing a slurry which overflows from the vessel over a screen having an aperture size in the range from 210 .mu.m to 500 .mu.m (No. 72 mesh to No. 30 mesh B.S sieve), there being retained on the screen a mixture of sand and mica having a higher percentage content of mica, as calculated in the dry state, than the feed mixture. The mica can be concentrated sufficiently to provide a suitable feed for a subsequent froth flotation process which conventionally requires a mica content of at least 25% by weight.

摘要： This invention provides a process and system for the segregation of used catalyst contaminated by the extended processing of hydrocarbon feedstocks. It utilizes multi-stage fluidization and segregation of the catalyst in an upflowing liquid, and recovery of the less contaminated catalyst upper fraction for reuse. The recovery vessel comprises at least two concentric compartments, either or both of which may preferably be tapered so as to provide less cross-sectional area at the upper end of the catalyst bed for improved fluidization of the used catalyst. The used catalyst material is usually introduced into the annulus between the vessel walls, and the lower density less contaminated fraction is accumulated within the inner compartment, from which it is withdrawn for reuse.

摘要： An impact scrubber for removing coating materials from the surfaces of particulate matter such as foundry sand and the like comprises a lift tube open adjacent upper and lower ends for containing a high velocity fluidized stream of said particulate matter. A fluid injector is mounted adjacent the lower end of the lift tube for moving the particulate matter into the lift tube to form an upwardly flowing, high velocity turbulent fluidized stream. An adjustable inlet valve is provided adjacent the fluid injector for regulating the flow of sand into the high velocity stream of fluid moving into the lift tube. A target is spaced above the open upper end of the lift tube providing an impact area for receiving the flow of high velocity fluidized particulate matter which impacts against the target. The coating material is loosened from the sand grains by the impact at the target and during the turbulent flow. The separated, heavier sand particles and the lighter coating materials are deflected downwardly by the target and a secondary fluid flow is provided to move outwardly of the lift tube for intercepting the downward curtain of particulate matter and coating materials and carrying away the lighter coating materials while permitting the heavier sand grains to continue to fall downwardly. An outlet fluid exhaust valve is provided for adjustably controlling the outflow of air and coating materials that are removed from the sand grains. A plurality of scrubbing units as described are arranged in series and a novel baffle system is provided to deflect a portion of the material from one unit into the next unit and recycle the remaining portion. Metering devices are provided for controlling the inflow and outflow of particulate matter and cleaned sand grains through the scrubber.
