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.

Iron Recycling - Cohen

Iron ore – most commonly, hematite and magnetite – goes through a process known as sintering to create pieces that are 10-25mm in size. These pieces enter the furnace along with coal (known as “coke” in this context), which provides the heat, and limestone, which makes any impurities in the ore rise to the top to form a layer called slag .
