How does Magnetic Separation work? In summary, the raw material or finished product is fed either by gravity, air, pumped or conveyor belt where it passes through or over a magnetic rod, grid, grate or plate. The magnetic field captures the ferrous contamination by attracting it to the magnetic tube or plate.

Dry magnetic separation of the ore samples under study was carried out on an SMBS-L laboratory drum magnetic separator with a magnetic induction value on the surface of the drum of the magnetic separator equal to B = 0.75 Tl, which provides maximum extraction of particles with magnetic properties and a rotation speed of the shell of the drum of ...
The magnetic fabrics of the Egletons granite (France ui.adsabs.harvard.edu › abs › 1988PEPIEven in cases of nearly homogeneous strain on the sample scale, analysis of anisotropy differences in numerous specimens close together in the same sample permits the separation of the magnetic fabrics related to the ferrimagnetic minerals and their ...
The heart of the magnetic separator is the magnetic drum assembly which is composed of a stationary magnetic array mounted inside of a non-magnetic drum. During operation, the drum revolves around the magnetic assembly thereby transporting magnetically attracted material on the drum to the area designated for discharge.
Magnetic Separation. Magnetic separation takes advantage of differences in the magnetic properties of minerals. Minerals fall into one of three magnetic properties: ferromagnetic, paramagnetic and diamagnetic. ... For example, if you were separating hornblende from a granite for Zr analysis, potential contamination by zircon inclusions in the ...
Purification of ilmenite from chromite impurities by a two step magnetic separation wherein magnetically susceptible chromite is magnetically removed, followed by an oxidizing roasting of the ilmenite and a subsequent magnetic separation of ilmenite from the remaining chromite impurities to obtain an ilmenite with 1% or less chromite.
