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.

Magnetic and Gravity Methods in Mineral Exploration: the

Magnetic methods are more popular in mineral exploration than gravity, not least because magnetic data can be quickly recorded from the air and in conjunction with other geophysical surveys. Land gravity surveys, by contrast, may require greater field efforts (Figs. 1, 5 and 6), more time, and more commitment of scarce capital.
