How does a magnetic separator separate ore?

Ore slurry is fed into the trough. Under the influence of the magnetic field, the magnetic particles in the slurry are magnetically concentrated and move toward the magnetic poles, where they are attracted to the separator's drum. The polarity of the magnetic poles remains stable during operation and alternates along the drum's rotation. As the concentrated particles rotate with the drum, the alternating magnetic poles create a magnetic agitation phenomenon. Non-magnetic minerals such as gangue that are trapped within the particles are dislodged by the continuous rotation of the drum and ultimately attracted to the surface of the magnetic separator drum, forming the concentrate. Non-magnetic and weakly magnetic minerals are discharged with the slurry as tailings.
