    Abstract: The present disclosure provides an apparatus for sorting a particulate material. The apparatus comprises a receiving portion for receiving the particulate material having a particle size within a predetermined range of sizes. The apparatus also comprises a distributor for receiving the particulate material at an upper end thereof and having a sloped distribution surface along which, in use, the particulate material passes substantially by gravity. A surface area of the sloped distribution surface increases towards a lower end of the distributor to facilitate a monolayer feed stream of the particles exiting and falling from a lower end of the distributor distributed as a curtain-like stream of particles. The apparatus further comprises a magnetic element for generating a magnetic force that is directed such that the particles of the falling feed stream that exit the lower end of the distributor have pathways that depend on magnetic properties of the particles. The apparatus also comprises sorting portions for sorting the particles based on the pathways of the particles.

    Abstract: Methods and apparatuses for separating metal values, such as nickel and nickel compounds, from mineral ores, including lateritic ores are disclosed. The method includes providing a mixture of particles (e.g., crushed and sized ore) that is composed of at least a first group of particles and a second group of particles. Group members have similar chemical composition, while particles belonging to different groups have dissimilar chemical compositions. The mixture of particles is concurrently, or generally concurrently, heated (using microwave/millimeter wave energy) and exposed to a reactant. The wave energy and the reactant act to increase the difference in either the magnetic susceptibility or other separation properties between the first and second group of particles. The mixture of particles is then passed through an appropriate separator to separate the particles of interest. Optional steps are disclosed for purifying selected particles. The reactant includes sulfur, sulfur compounds, halogens, or halogen compounds.

    Abstract: Magnetic composites exhibit distinct flux properties due to gradient interfaces. The composites can be used to improve fuel cells and batteries and effect transport and separation of different species of materials, for example, transition metal species such as lanthanides and actinides. A variety of devices can be made utilizing the composites including a separator, an electrode for channeling flux of magnetic species, an electrode for effecting electrolysis of magnetic species, a system for channeling electrolyte species, a system for separating particles with different magnetic susceptibilities, improved fuel cells, batteries, and oxygen concentrators. Some composites can be used to make a separator for distinguishing between two species of materials and a flux switch to regulate the flow of a chemical species. Some composites can control chemical species transport and distribution. Other composites enable ambient pressure fuel cells having enhanced performance and reduced weight to be produced. Still other composites enable rechargeable batteries to be made that have longer secondary cycle life and improved output power. Methods involving these composites provide distinct ways for these composites to be utilized.

    Abstract: A method of quantitative analysis of microscopic biological specimens in a fluid medium is disclosed in which the specimens are rendered magnetically responsive by immunospecific binding with ferromagnetic colloid. A known quantity of magnetically-responsive marker particles are added to the fluid medium. The fluid medium is then subjected to a magnetic separation process, to collect the magnetic species from the fluid. The collected species are resuspended in a second fluid medium, and the relative quantities thereof are enumerated to determine the concentration of the desired biological specimen in the first fluid medium. The marker particles may comprise magnetic particles having a relatively large magnetic moment, a magnetic moment approximately equal to the magnetically-labelled biological speciment of interest, or both in order to compensate the determination for variations in immunospecific binding affinity and/or magnetic collection efficiency. The present method is useful for conducting hematological assays, such as red blood cell counts and related determinations. In the case of red blood cells, the specimens may be rendered magnetically responsive by reduction of the iron atoms present in hemoglobin. The enumeration step of the method may be conducted with such equipment as a flow cytometer, or by a novel optical scanning magnetic cell immobilization apparatus.

    Abstract: Biological entities such as cells, microbes, or components thereof are labeled with a magnetic colloid containing microscopic magnetic particles. The magnetic particles have a coating capable of biospecific or non-specific binding with the entities. An immobilization apparatus includes a non-magnetic vessel having a ferromagnetic collection structure for attracting the entities toward a collection surface upon which the magnetically labeled entities are immobilized subsequent to placement of the vessel on a support between two magnets. The ferromagnetic collection structure preferably has a sharp edge or high curvature for intensifying the magnetic field and for collecting the entities in a monolayer. The vessel includes an un-obstructed observation path so that immobilized entities may be observed and/or manipulated. The ferromagnetic collection structure may be arranged in various two dimensional patterns to provide a desired collection configuration. The apparatus may further have inlet and outlet ports for allowing a flow of liquid reagent through the vessel for washing or straining the immobilized entities. The support can be translated so that a shoulder on the collection structure concentrates the collected entities by movement of the shoulder in a transverse direction relative to the magnetic field.

    Abstract: Improved magnetic separation devices for magnetic separation procedures are provided. The improved separation devices contain matrices which provide uniform pores or channels that reduce the entrapment of air or non-target substances, and decrease the loss of target substances due to mechanical disruption. Target cells, from various systems and organs, or other target biological substances are labeled in conjunction with a suitable specific binding member, and isolated using the devices and methods of the present invention. In its simplest form, the cell separation system of the present invention has two main components: a magnetic separator and a cell separation reagent. A more complex separation device includes fluid passages, collection and storage containers and the separation column. The fluid circuitry can be constructed with integrated valves, or the valves may be applied externally to the fluid pathways.

    Abstract: In a process for separating relatively magnetic mineral particles P.sub.m having magnetic susceptibilities .chi..sub.m, with .chi..sub.m >0 from relatively non-magnetic particles P.sub.n, having magnetic susceptibilities .chi..sub.n, with .chi..sub.m >.chi..sub.n, all the particles are suspended in a liquid stream, which is supplied to a separating container. The container is provided with an inlet and an outlet and forms a passageway for the stream therebetween. Furthermore an arrangement of magnetizable matrix elements provided in the passageway is magnetized. The supplying and magnetizing are conditioned in such a way, that depositions of particles are obtained predominantly upon the downstream side of the elements. From all the particles magnetic particles P.sub.m are captured to an effective amount upon the downstream side, thereby resulting in a high grade deposition.
