The current invention relates to the method and apparatus to magnetically separate biological entities with magnetic labels from a fluid sample. The claimed magnetic separation device removes biological entities with magnetic labels from its fluidic solution by using a soft-magnetic center pole with two soft-magnetic side poles. The claimed device further includes processes to dissociate entities conglomerate after magnetic separation.

A method of operating a magnetic selector is provided. The magnetic selector includes a housing including a floor having a floor surface, a magnet carrier disposed on an opposite side of the floor from the floor surface and having at least one magnet disposed thereon, the magnet carrier being moveable relative to the floor between a first state wherein the magnet carrier is adjacent the floor and a second state wherein the magnet carrier is spaced from the floor. The method includes disposing a container on the floor surface, moving the magnet carrier to the first state to apply a magnetic field to a fluid in the container, moving the magnet carrier to the second state from the first state to disengage the magnetic field from the container, and removing the container.

A purification apparatus includes a holding unit including a bottom plate for supporting a bottom portion of a container to be mounted, and a magnetic unit arranged on the bottom plate or below the bottom plate so as to face the bottom portion of the container. The magnetic unit fixes magnetic particles of an amorphous metal to an inner bottom portion or an inner wall of the container so as to separate a liquid in the container and the magnetic particles contained in the liquid from each other and/or to collect the liquid while leaving the magnetic particles in the container.

An apparatus for processing magnetic particles comprises a sealed enclosure and a magnetic field source. The sealed enclosure comprises an inlet into the enclosure and an outlet from the enclosure. The configuration of the sealed enclosure and of the inlet and the outlet are such that fluid containing the magnetic particles that is introduced into the enclosure through the inlet exhibits a spiral flow towards the outlet. The magnetic field source is disposed to the enclosure to intermittently apply a magnetic field to the fluid contained therein.

A method and system for separating valuable material, such as precious metals and rare earth elements, from a raw material, such as coal, is disclosed. The system may include a crusher or pulverizer for producing finely crushed material. This crushed material may be made into a slurry and placed into an econosizer for separating material by its specific gravity. High specific gravity material may be further refined using magnets, separators, or centrifuges, among other disclosed components of the system.
