Other minerals, such as magnetite, contain higher concentrations of iron, but hematite is so much more abundant that it is the most economically important iron ore. In North America, over 90% of our iron comes from hematite deposits and without hematite our steel-based society could not exist. The use of iron and steel throughout the industrial ...

Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3 ). Iron ore is the source of primary iron for the world's iron and steel industries.

Magnetite, with the chemical formula Fe3O4, is one of the primary iron ores and is known for its strong magnetism. Hematite, on the other hand, has the formula Fe2O3 and is also a significant source of iron but lacks natural magnetism. Both are iron oxides, but they differ in their chemical composition, which results in different properties.
