for MNPs is the use of so-called high gradient magnetic separators [31,32]. However, the strong magnetic ﬁelds and ﬁeld gradients used in these apparatus result in a practically complete separation of all magnetic particles in the feed stream. Therefore, these separators only have very limited efﬁciencies when being considered for size

The separator magnet has a central longitudinal axis about which the separator magnet is rotatable relative to the sleeve. When the separator magnet is driven into axial rotation, the magnetic particles experience a moving gradient of magnetic field strength perpendicular to the helical groove, which the particles will follow.
