Iron Ore
Description: Iron ore is the primary raw material used to make iron and steel. It is a natural mineral found in the earth’s crust, containing iron oxides like hematite (Fe₂O₃) and magnetite (Fe₃O₄).
Uses: The iron extracted from iron ore is used primarily in steelmaking. The iron ore is first processed into a usable form, usually by reducing it in a blast furnace or direct reduction plant, to produce pig iron or sponge iron, which is then converted into steel.

Types:
Hematite: Contains about 70% iron and is the most important iron ore.
Magnetite: Contains about 72% iron and is often processed into iron ore pellets.
Processing: Iron ore is typically mined, crushed, and then concentrated by removing impurities. It can be used directly in blast furnaces or processed into pellets for use in direct reduction processes.
