Magnetic separation theory The magnetic separation of magnetite and other magnetic minerals is a complex process. During the separation process, each particle is subjected to a number of forces, including grav-ity, drag, etc. The simplified equation below describes the magnetic force the particles are subjected to: Magnetic force:
