Granular materials can be separated on the basis of contrasts in magnetic susceptibility. This is done using first a strong permanent magnet made of Samarium-Cobalt.If working with minerals, the less magnetic fraction (richer in feldspars and quartz) can then be introduced to the Frantz barrier separator (see photo). If working with volcanic groundmass that is rich in very fine grained iron
