Physical Properties Of Ilmenite. Ilmenite is a black mineral found in mafic igneous rocks and pegmatites. It belongs to the iron titanium oxide minerals group, which also includes rutile, anatase, brookite, and perovskite. Ilmenite has a hardness of 5.5-6 on the Mohs scale, making it durable enough for use as an abrasive or gemstone polish.
