Abstract: A method for integrated processing of finely dispersed metal-containing waste, wherein the method includes mixing metal-containing waste with magnetic field activated water into a pulp, subjecting the pulp in a reaction chamber to a rotating magnetic field generated by rotating ferromagnetic elements, carried out in a vortex layer with a rotation speed of the ferromagnetic elements being at least 2800 rpm, until a magnetostriction effect and subsequent reduction of metal oxides occurs, and carrying out hydrocyclone separation of the metal oxides.

Abstract: A magnetic filter is disclosed suitable for use in large heating and/or cooling systems, for example heating systems using pipework between 2 inch bore and 4 inch bore. The magnetic filter includes a separation chamber in the form of a pipe, and externally-mounted magnetic 5 assemblies which are movable from a position close to the pipe to a position spaced from the pipe. The magnetic assemblies are pivotally mounted to the pipe via a framework.

Abstract: The present invention relates to a method for isolating a nucleic acid by using: a binding buffer containing acetic acid or phosphoric acid; and the pH difference between binding and washing buffers, and an elution buffer, wherein silica magnetic particles are added to a biological sample including a nucleic acid to which a binding buffer containing acetic acid, phosphoric acid, etc., has been added, thereby binding the nucleic acid to the magnetic particles, after which a magnetic field is applied to separate the magnetic particles, and the nucleic acid is purified in a basic pH elution buffer. The method uses the pH difference, and can isolate the nucleic acid more quickly and efficiently than centrifugation or gravity separation. In addition, since ethanol is not used, high-purity nucleic acid can be isolated and purified to obtain more accurate results in subsequent experiments.

Abstract: Methods and apparatus for processing fluids are described. In various aspects, a fluid processing system may include a magnetic assembly that includes a plurality of magnetic structures configured to generate a magnetic field gradient within a fluid container. The magnetic structures may be formed as a plurality of electromagnets configured to be individually actuated by a controller. Each of the electromagnets may generate a magnetic field within the fluid container. The electromagnets may be differentially actuated to create a magnetic field gradient within the fluid container to agitate, mix, or otherwise influence magnetic particles disposed within the fluid container. Activation of the electromagnets of an electromagnetic structure may generate a magnetic field gradient that influences magnetic particles in an x-y direction. In addition, activation of the electromagnets of a plurality of electromagnetic structures may generate magnetic field gradients that influences magnetic particles in an x-y direction and z-direction.

Abstract: A pneumatically-operated magnetic separator captures magnetic contaminants from process fluids. Process fluids are used in many industrial operations for various purposes. The pneumatically-operated magnetic separator can include a housing wall, a first flange plate assembly, a second flange plate assembly, a main fluid passage, tubes, and shuttles. The first and second flange plate assemblies can each include a pair of flange plates. The tubes extend between the first and second flange plate assemblies, and the shuttles are situated in the tubes. Each of the shuttles includes one or more magnets. During use, the shuttles move longitudinally in the tubes in response to pneumatic actuation and de-actuation, per an example. Weldments attach the tubes and the first and second flange plate assemblies together.
