Magnetic separation for mining industry – Magnetense

The non magnetic particles are moved down to the lower hopper following the gap of the lower magnetic pole and the magnetic separation of magnetic minerals is completed. At this point the pulsating box is activated causing the pulp shaking up and down in order to remove impurities and improving the concentration of the pulp.

Particle Analysis in Mining and Minerals - HORIBA

Electrostatic and Magnetic Separation. The behavior of a particle under electrostatic or magnetic fields can be exploited to separate particles by type. These fields will induce charges (or magnetism). The resulting forces will cause particles to move depending on particle mass. Thus small particles are moved further than large particles.

Mineral processing - Wikipedia

Magnetic separation is a process in which magnetically susceptible material is extracted from a mixture using a magnetic force. This separation technique can be useful in mining iron as it is attracted to a magnet. In mines where wolframite was mixed with cassiterite, such as South Crofty and East Pool mine in Cornwall or with bismuth such as ...
