Abstract. All materials respond in some way to a magnetic field so that all minerals have magnetic properties. Minerals which contain no ions with uncompensated spins (e.g., an absence of, notably, the transition series elements) are diamagnetic.Those containing transition elements in low concentrations are paramagnetic.The ratio of the magnetic susceptibilities of these two categories of ...

Jacobsite-Magnetite Series. Magnesioferrite-Magnetite Series. Magnetite is an important iron ore, along with hematite. Nanoinclusions of magnetite crystals cause the iridescence of Rainbow obsidian (Nadin, 2007). Extremely thin layers of 200-nm octahedral crystals of magnetite give some basalt surfaces an iridescent sheen (Nadin, 2007).

Ilmenite: An ore of titanium | Uses and Properties

Magnetic mineralogy is the study of the magnetic properties of minerals. The contribution of a mineral to the total magnetism of a rock depends strongly on the type of magnetic order or disorder. Magnetically disordered minerals (diamagnets and paramagnets) contribute …

Magnetite is strongly magnetic. It was used by the ancient Chinese to make the first magnetic compasses. The chemical formula is Fe 3 O 4, commonly called ferrous-ferric oxide, and is valuable as an iron ore.. Magnetite reacts with oxygen to produce hematite, another iron ore.

Physical Properties of Ilmenite. Ilmenite is a black mineral with a submetallic to metallic luster. With just a glance it can easily be confused with hematite and magnetite. The differentiation is easy. Hematite has a red streak, while ilmenite has a black streak. Magnetite is strongly magnetic, while ilmenite is not magnetic.
