Abstract. Magnetic separation utilizes the force of a magnetic field to produce differential movement of mineral particles through a magnetic field; this and the fundamental differences in the magnetic susceptibility of minerals constitutes the basis of separation to effectively obtain purification or concentration of mineral products.
The primary variables affecting separation using an IRM separator are the magnetic susceptibility of the mineral particles, the applied magnetic field intensity, the size of the particles, and the speed of the roll (Singh et al., 2013). The setting of the splitter plates cutting into the trajectory of the discharged material is also of importance.

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.

· The magnetic force F(m) generated on a paramagnetic particle in a magnetic separator is given by: F(m) = V.K.H.H/R For a successful separation, the magnetic force F(m) must be able to move the paramagnetic mineral from its natural path immediately after leaving a separator, or lift it from a belt (overcoming gravity) in the case of a Disc type ...
