Magnetic separation theory The magnetic separation of magnetite and other magnetic minerals is a complex process. During the separation process, each particle is subjected to a number of forces, including grav-ity, drag, etc. The simplified equation below describes the magnetic force the particles are subjected to: Magnetic force:

The separator, or disc centrifuge, is a vertically arranged centrifuge. It is used for separating and clarifying liquids. In a disk stack separator, solid-liquid mixtures or liquid-liquid mixtures are separated by centrifugal force. Compared to a decanter centrifuge, the separator differs significantly in its technical design and application.

The principle of eddy current separation introduced in this article is shown in the Figure below. A rotating drum wrapped by a permanent magnet ( High Performance NdFeB Magnets) produces a alternating magnetic field. When a metal with conductive properties passes through the magnetic field, an eddy current will be generated in the metal.

Magnetic separation is used for clinical application, such as in the separation of proteins, toxemic materials, DNA, and bacteria and viruses. This is also used for real time detecting of viruses. The most important stage in this field is the labeling of molecules with magnetic materials by a reliable connection.

As a consequence, new applications and design concepts in magnetic separation have evolved. This has resulted in a wide variety of highly effective and efficient magnetic separator designs. In the …

WHIM is the short acronym for Wet High Intensity Magnetic Separation . At present, most U.S. iron raw materials are produced from magnetic taconites, which are ground to a nominal minus 270 mesh (53 micrometers), beneficiated by wet low-intensity magnetic separation, and pelletized. The taconite ore bodies generally contain 19 to 25 …

Batch magnetic separators. Batch magnetic separators are usually made from strong rare-earth permanent magnets embedded in disinfectant-proof material. The racks are designed to hold various sizes and numbers of tubes. Some of the separators have a removable magnet plate to facilitate easy washing of magnetic particles (Figure 1 ).
