As the foremost source of iron ores on the planet, hematite has shaped civilizations for thousands of years. The mineral was first used as the main pigment in cave paintings often having a reddish hue, a signature trait of hematite.. Later, it was — and still is — the primary source of iron, shifting the world out of the Stone Age and into the Iron Age.

Composition: Hematite consists of iron (Fe) and oxygen (O) atoms, with two iron atoms bonded to three oxygen atoms in each formula unit (Fe2O3). Iron Content: Hematite is a rich source of iron, typically containing about 70% iron by weight. This high iron content makes it an important ore for iron extraction and steel production.

Iron Ore Iron ore is the rock that contains iron elements or there are iron deposits in it. Economical iron deposits are generally in the form of magnetite, hematite, limonite, and siderite [3]. Iron ore deposits can be formed primary or secondary. Primary iron ore deposits can be formed by magmatic, contact metasomatic, and hydrothermal processes.
