The magnetic particle separator uses an induced magnetic field to separate magnetic particles held in solution by magnetophoresis. The magnetic particles may be, for example, inherently paramagnetic or superparamagnetic, may be magnetically tagged or the like. First and second magnetic particles initially flow along a longitudinal direction. An external magnetic field along a lateral direction, orthogonal (or near orthogonal) to the longitudinal direction, is applied to an externally magnetizable wire, which extends along a transverse direction orthogonal to both the longitudinal and lateral directions. The external magnetic field generates an induced magnetic field in the externally magnetizable wire, and the induced magnetic field generates repulsive magnetic force on the first and second magnetic particles. Due to differing magnetic susceptibility, size and/or mass between the first and second magnetic particles, they are separated by following separate paths generated by the respective magnetic forces thereon.

The present invention relates to a microparticle separation apparatus assembly comprising multiple separable panels, more specifically, to a microparticle separation apparatus assembly having a novel structure, comprising: a first panel comprising a magnetic microstructure for applying magnetophoretic force to microparticles; and a second panel, which can be separated from the first panel and through which a sample comprising microparticles passes, wherein the first panel comprising the magnetic microstructure can be recycled.

In at least one illustrative embodiment, an electromagnetic filter may include a pipe and a magnetic field generator such as an array of permanent magnets. The magnetic field generator generates a magnetic field through a filter section of the pipe. Multiple filter elements are positioned within the filter section of the pipe. The filter elements include a magnetic material and a biorecognition element to bind with a microorganism. The biorecognition element may be a bacteriophage that is genetically engineered to bind with the microorganism. The magnetic field forces the filter elements to positions within the filter section of the pipe. A fluid media may be flowed from an inlet of the pipe to an outlet of the pipe, through the filter section. The fluid media may be a liquid food such as fruit juice. Other embodiments are described and claimed.

A process is provided for obtaining a hematite-containing material that can be used for ironmaking. The process includes separating a leach residue from a hydrometallurgical refining plant into an overflow and an underflow using a wet cyclone under a condition that the wet cyclone is adjusted to have a setting between 1 m or less and 2 m or less as a classification particle size for the overflow. The process then includes separating the overflow into a strong magnetic substance and a weak magnetic substance using a strong-magnetic-field magnetic separator under a condition that magnetic field intensity is 5 to 20 [kGauss]. The process then includes using a superheated steam drying system for adjusting a moisture content of the strong magnetic substance after the separation, to be 10 wt % to 17 wt %.
