Gradient Magnetic Separation an overview

Joan S. Esterle, in Applied Coal Petrology, 2008. 3.7.5 Magnetic Separation. High gradient magnetic separation (HGMS) (Trindale et al., 1974, and Liu, 1982) is based on coal being diamagnetic (repulsed by a magnet), whereas pyrite is paramagnetic (attracted to a magnet). The magnetic susceptibility of pyrite is 0.3 × 10-6 G/g (G = gauss), compared to coal at -0.4 × 10-6 to –0.8 × 10-4 G/g.
