Hematite: A primary ore of iron and a pigment mineral

Hematite is the world’s most important ore of iron. Although magnetite contains a higher percentage of iron and is easier to process, hematite is the leading ore because it is more abundant and present in deposits in many parts of the world. Hematite is mined in some of the largest mines in the world.

Is Hematite Magnetic? - Techie Scientist

Jan 22, 2021 · Yes, hematite being an iron ore is magnetic in nature. It is antiferromagnetic in nature below the Morin transition ie; approximately at 250 K. And it acts as a weak ferromagnet above the Morin transition and Neel temperature, which is approximately 948 K. In addition to this, hematite above the Neel temperature is a pure paramagnet.

MAGNETITE (Iron Oxide)

Magnetite is an oxide of iron (as is hematite).It is not a component of ordinary rust, although it can form as iron oxidizes in a dry environment. When you see sparks from welding operations or from iron striking a hard surface (as when it is held against a spinning grinder), the sparks are due to the rapid (and exothermic) oxidation of tiny particles of iron into magnetite.
