Hematite Mineralogy Geology. Polished mineral hematite and magnetic hematite are visually very similar. It is easy to confuse the mineral hematite with the man-made material that goes by the name "magnetic hematite." In certain forms, both share a very similar silvery appearance. In addition, both are often confused with the mineral magnetite.
induced magnetization of hematite could compete with magnetite in weak magnetic fields up to 1 mT. TRM acquisition curves of magnetite and hematite show that multidomain hematite approaches TRM saturation 0.3–0.4 A m 2rkg in fields. as low as 0.1 mT. However, multidomain magnetite reaches only a few percent of its TRM saturation in a …
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.
The biggest difference between these stones is that hematite is paramagnetic and magnetite is ferromagnetic. This means that magnetite is highly magnetic, whereas hematite is only weakly magnetic. Color . Hematite is a metallic grey color, whereas magnetite is much darker, black to dark grey.
