The magnetic gradient tensor provides a powerful tool for detecting magnetic bodies because of its ability to emphasize detailed features of the magnetic anomalies. To interpret field measurements obtained by magnetic gradiometry, the forward calculation of magnetic gradient fields is always necessary. In this paper, we present a contraction …

Gradient Magnetic Separator. In HGMS, a ferromagnetic matrix element is introduced into the applied magnetic field to create many points of high field gradient with the intention of capturing the magnetic particles and allowing nonmagnetic particles to flow through the separator. From: Wills' Mineral Processing Technology (Eighth Edition), 2016.

The high gradient magnetic separator (HGMS) is a strong magnetic separator for the screening of weakly magnetic minerals. It is a new type of strong magnetic separator developed on the basis of a general magnetic separator machine. It also used for wet magnetic separation of magnetite, pyrrhotite, roasting ore, ilmenite and other …

In high gradient magnetic separation in mineral processing, the magnetic field is seldom above 2.5T. So the influence of magnetic flocculation on the recovery of weakly minerals is very slight. Moreover, as the very fine minerals are highly liberated, the flocculation of these fine minerals in high magnetic field will help to improve the ...

Superconducting High Gradient Magnetic Separation (SHGMS) is a technology developed on the basis of the High Gradient Magnetic Separation (HGMS) technology of the 1970s . Its magnetic field strength reaches 3~7 T, which is several times that of ordinary electromagnetic magnetic separators.

High-gradient magnetic separation (HGMS) is indispensably applied in the rougher separation stage of refractory weakly magnetic minerals. The most difficult problem while processing refractory weakly magnetic minerals is the low selectivity of HGMS caused by the competing capture of magnetic valuable and gangue minerals.
