摘要： A method of separately extracting mercury and gold from mine tailings includes a centrifugal separator comprising a centrifuge bowl having a plurality of annular rings on the peripheral surface. An outer bowl or sleeve member provides a jacket from which water is injected through holes in the inner bowl into recesses between the annular rings. Feed materials containing gold and mercury are separated so that the gold and mercury is collected with the heavies in the recesses. The liquid mercury escapes through the holes in the inner bowl onto the inner surface of the outer bowl which is provided with an annular receptacle and is shaped to collect the mercury at the receptacle axially spaced from the open mouth of the bowl. A plurality of outlets in the annular receptacle allow the escape of the mercury into a secondary launder inside the outer launder for the main discharge materials from the open mouth. The liquid mercury is thus collected separately from the solid heavies within the bowl and separately from the discharged light material.

摘要： A sample collection container having inner and outer chambers. The container may be fitted with upper and lower stoppers to provide a vacuum within the container. The device is adapted for the collection of a fluid, such as blood, in the inner chamber. The blood then passes from the inner chamber to the outer chamber upon releasing the vacuum. A concentrate of fluid components of blood, cellular debris, and contaminating microorganisms, if present, may be left in the inner chamber, and be removed subsequently from the inner chamber for testing for the presence of contaminating microorganisms.

摘要： A hydrodynamic device for generating negative pressure excursions in a pulp slurry during fine screening, includes at least one half-foil member disposed on a substantially cylindrical outer surface of a rotor. The rotor is mounted within and co-axial with a substantially cylindrical screen having a circumferentially continuous apertured zone to define an annular screening chamber between the rotor and the screen. The half-foil member is collectively at least axially co-extensive with the apertured zone and has a leading edge which, also collectively, is inclined at a spiral angle relative to the axis of the rotor such that, in one embodiment, during rotation, the leading edge of the half-foil member conducts large particles downwardly through the screening chamber. A selection of hydrodynamic foil configurations is provided in order to adapt to a wide range of pulp types and screening conditions.

摘要： A method and apparatus are provided for acoustophoresis, i.e., the separation of species via acoustic waves. An ultrasonic transducer applies an acoustic wave to one end of a sample container containing at least two species having different acoustic absorptions. The wave has a frequency tuned to or harmonized with the point of resonance of the species to be separated. This wave causes the species to be driven to an opposite end of the sample container for removal. A second ultrasonic transducer may be provided to apply a second, oppositely directed acoustic wave to prevent undesired streaming. In addition, a radio frequency tuned to the mechanical resonance and coupled with a magnetic field can serve to identify a species in a medium comprising species with similar absorption coefficients, whereby an acoustic wave having a frequency corresponding to this gyrational rate can then be applied to sweep the identified species to one end of the container for removal.

摘要： The use of electrostatic demulsification methods to separate fine particulates of differing surface characteristics is disclosed. In one example, particles of hydrophobic coal and hydrophilic kaolin clay, each of nominal 3.5 micron mass mean particle diameter, were separated from a variety of stable water-in-oil emulsions. 50/50 blends of coal of 4% ash and kaolin clay of 86.5% ash were used in the experiments. A variety of oils, water concentrations, solids concentrations, and emulsifiers have been used in this work. Externally applied electrostatic fields up to 1.2 kV/cm were used. Greater than 90% rejection of kaolin particles into the separated water phase was achieved with virtually complete recovery of the coal particles uniformly suspended in the oil phase. Under conditions resulting in the most efficient separation, we have observed that the coalesced water phase appeared as intertwined cylindrical tubes extending between electrodes, as opposed to nonconnected and chained droplets which have been reported by others. The fine kaolin particulates were observed to be water-encased while most coal particles remained dispersed in the oil continuum.

摘要： This invention provides an apparatus and method for the complete fractionation of submicron particles according to size by capillary hydrodynamic fractionation. This objective is achieved by using small diameter capillaries; introducing a minor fraction of a liquid dispersion of particles to be separated into at least one capillary fraction; passing the minor fraction through the capillary; and, at the exit of the capillary, diluting the minor fraction with the same liquid as is carrying the fractionated sample. These modifications in the flow patterns are essential to the use of capillaries with diameters smaller than 60 microns. This invention is especially adapted for rapid analytical separation of not only rigid colloidal particles but also of soft latexes.

摘要： A process for continuous particle and polymer separation comprising injecting a stream of carrier fluid containing the material to be separated into the inlet end of a thin channel, adjusting the flow rate to a sufficiently high level that flow-dependent lift forces the different components to different transverse positions by the time they reach the end of the channel, splitting the outlet flow into at least two substreams by means of physical splitters, adjusting the flowrates of the multiple substreams such that the transverse position of the outlet splitting plane divides the particles into enriched fractions, collecting the enriched or separated components from the emerging outlet streams.

摘要： The separation of different types of particulate matter in a carrier liquid is obtained by using an ultrasonic standing wave and relying on the different acoustic responses of the different particle types. By varying the acoustic energy propagation cyclically a more effective separation rate can be obtained, with a more readily attracted particle type being subjected to a further discrimination step in each cycle. The cyclical energy variation may be in the intensity of the standing wave, e.g. using suppression means, and/or the velocity of the standing wave relative to the liquid medium, e.g. using phase control means.
