Hematite: A primary ore of iron and a pigment mineral - Geology

Hematite has a wide variety of other uses, but their economic significance is very small compared to the importance of iron ore. The mineral is used to produce pigments, preparations for heavy media separation, radiation shielding, ballast, and many other products. Hematite's Streak: All specimens of hematite will produce a reddish streak.
