| A method for separating particles in a biofluid includes pretreating the biofluid by introducing an additive, flowing the pretreated biofluid through a microfluidic separation channel, and applying acoustic energy to the microfluidic separation channel. A system for microfluidic separation, capable of separating target particles from non-target particles in a biofluid includes at least one microfluidic separation channel, a source of biofluid, a source of additive, and at least one acoustic transducer coupled to the microfluidic separation channel. A kit for microfluidic particle separation includes a microfluidic separation channel connected to an acoustic transducer, a source of an additive, and instructions for use. | ||||||

| An apparatus and method for collecting mineral particles in the tailings is disclosed. The apparatus may take the form of a filter, a conveyor belt, a collection plate or an impeller configured to contact with tailings of a flotation process, before and/or after the tailings are discharged into a pond. The filter, conveyor belt, collection plate or impeller has a collection area or surface made of, or coated with, a synthetic material having a functional group, e.g., having an ionizing bond to attract the mineral particles of interest. Alternatively, the synthetic material has hydrophobic molecules to render the collection area hydrophobic. When the mineral particles of interest in the tailings are combined with collector molecules, the mineral particles of interest may also become hydrophobic. The hydrophobic mineral particles of interest are attracted to the hydrophobic collection area or surface. The filter, conveyor belt, collection plate and impeller may have a plurality of passage ways or synthetic beads in order to increase the contacting surfaces. | ||||||

| Fine coal is cleaned of its mineral matter impurities and dewatered by mixing the aqueous slurry containing both with a hydrophobic liquid, subjecting the mixture to a phase separation. The resulting hydrophobic liquid phase contains coal particles free of surface moisture and droplets of water stabilized by coal particles, while the aqueous phase contains the mineral matter. By separating the entrained water droplets from the coal particles mechanically, a clean coal product of substantially reduced mineral matter and moisture contents is obtained. The spent hydrophobic liquid is separated from the clean coal product and recycled. The process can also be used to separate one type of hydrophilic particles from another by selectively hydrophobizing one. | ||||||

| A defined mineral phase is separated from a ground ore having several chemical phases and being present in a heterogeneous particle size distribution by classifying the ore according to a defined particle diameter into at least two fractions, a first fraction having particles essentially larger than the defined particle diameter and a second fraction having particles essentially smaller than the defined particle diameter, and the defined mineral particles of value being present in both fractions, floating the first fraction having the greater particle diameters and selecting the defined mineral particles of value in a flotation concentrate, selectively admixing the defined mineral particles of value in the fraction having the smaller particle diameters with magnetizable particles, applying a magnetic separation process to the second fraction having smaller particle diameters, and separating a concentrate with an enrichment of the defined mineral phase of value. | ||||||

| A process for cleaning and dewatering hydrophobic particulate materials is presented. The process is performed in two steps: 1) agglomeration of the hydrophobic particles in a first hydrophobic liquid/aqueous mixture; followed by 2) dispersion of the agglomerates in a second hydrophobic liquid to release the water trapped within the agglomerates along with the entrained hydrophilic particles. | ||||||

| The invention relates to a method for separation of elements from a fluid using affinity-bearing particles suspended in the fluid and using ultrasonic standing waves and micro-fluidics. The method includes the steps of: mixing said fluid mixture with particles (10) having affinity to at least one element (9) to be separated; allowing the element (9) to be separated to bind to said affinity-bearing particles (10); subjecting the fluid to an ultrasonic wave field resulting in forces on the affinity-bearing particles (10) but substantially no forces on elements not bound to affinity-bearing particles; and allowing said forces to move said affinity-bearing particles (10) to a portion of the fluid thus obtaining a locally higher concentration of affinity-bearing particles. The method may be performed in a process with continuous flow. | ||||||

| Comminuted carpet pieces are fed to a first stirred tank together with an aqueous solution containing separating salt, to form a first suspension, which is fed to a first mechanical separating stage. A first high-solids phase, a second high-solids phase containing polymer fiber material, and a liquid phase are obtained therefrom. The second high-solids phase is mixed with a water-containing separation solution in a stirred tank, to give a second suspension, which is fed to a second mechanical separating stage. A third high-solids phase, a polymer fiber material-rich phase and a liquid phase are withdrawn therefrom. An acid which is stronger than H2CO3 is introduced into the stirred tank together with the water-containing separation solution, and the pH of the liquid in the stirred tank is adjusted to 2–6. | ||||||
| 235 | Method of separation by altering molecular structures | US10092281 | 2002-03-06 | US06905028B2 | 2005-06-14 | Durham Russell Maples |
| Method of separation that uses at least one organic chemical reaction to alter the molecular structure of a substance or substances (102) so that a mechanical method of separation can be used to cause the separation of one or more substances from one or a group of substances (104). The organic chemical reaction alters the molecular structure by adding at least one atom to the molecular structure or by subtracting at least one atom from the molecular structure. The mechanical method of separation uses the differing physical characteristics of substances to physically change the place or position of substances to remove or isolate the substances from a combination or a mixture absent any chemical reaction. The organic chemical reaction and the mechanical method of separation are used in combination to cause the separation of substances that otherwise could not be separated by the mechanical method of separation alone. | ||||||

| The present invention relates to a method of separating a machining suspension into fractions including abrasive grains and attrition material, such as a suspension produced in the course of the mechanical machining of silicon, quartz or ceramic material, from a cutting fluid in which abrasive grains and the attrition material are dispersed that originates from the machined material and from the machining equipment. In the method, the suspension is separated by means of wet classification, with the liquid used for the sizing process being selected in such a way that it can be mixed with the used cutting fluid and with the mixture so formed, which contains the attrition material originating from the machined material in particular, forming a stable suspension. | ||||||

| 239 | Process for removing impurities from kaolin clays | US09818693 | 2001-03-27 | US20010022282A1 | 2001-09-20 | D. R. Nagaraj; Roderick G. Ryles; Alan S. Rothenberg |
| An improved process for the selective flocculation of impurities from clays is disclosed. The process comprises blunging the clay in the presence of dispersing agents, conditioning the blunged clay with aliphatic or aromatic hydroxamic acids, or salts thereof, flocculating the impurities with a high molecular weight polymeric flocculant, particularly polymers containing hydroxamate groups, and removing the flocculated impurities from the unflocculated clay. The use of hydroxamic conditioning agents improves the removal of impurities from the clay, thereby providing a clay product having high brightness and low level impurities. The hydroxamic acid conditioning agents may advantageously be used in combination with other conditioning additives and with a wide variety of polymeric flocculating agents. | ||||||
