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.
