High Gradient Magnetic Separation of Iron Oxides and other , - Know More
Although mica, vermiculite, and smectite are often found in both the tailings and the magnetic fraction, vermiculite and mica appear to be more concentrated in the magnetic fraction The concentration effect on kaolinite appears to be dependent on the particle size and rate of flow through the magnetic filter...

Principles of Magnetic Separation - Know More
06-10-2021 0183 32 Figure Schematic representation of forces acting upon a particle Svoboda et aI, 2003 The principles of magnetic separation are such that when particles of different magnetic susceptibility are placed in a magnetic field, they tend to disrupt the direction or the flow of the magnetic field and at the same time lead to the particles being magnetically induced...
