ore particles magnetic separation

MAGNETIC SEPARATION N. Chakravorty

The magnetic separation may be for removing ore particles which are magnetic or conversely to remove magnetic impurities from a product which is non-magnetic. Examples are Magnetite from Quartz or Magnetite and Wolframite from Cassiterite. All materials are affected in some way when placed in a magnetic field, although with most substances the

Principles of Magnetic Separation - Minerallurgy

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.
