Introduction. Modern high-gradient magnetic separation (HGMS) initially originated from a magnetic filter patented in 1937 by Frantz [1], in which the ferromagnetic matrix of fine wires or rods was first introduced into a uniform magnetic field to increase the magnetic field gradient by several orders of magnitude [2].
