G.W. Heyes, in Iron Ore, 2015. 11.3.2.3 Sulfur removal. Magnetite ores often contain sulfide minerals including pyrrhotite and pyrite. Most sulfide minerals are nonmagnetic and can be rejected by magnetic separation. Monoclinic pyrrhotite, however, in contrast to hexagonal pyrrhotite, is magnetic and is recovered in magnetic concentrates
