Iron Ore: From Mining to Processing to Dust Control
Ninety-eight percent of iron ore mined goes into producing steel, the world's most common metal. By definition, steel is the element iron (99%) combined with carbon (1%). The iron in iron ore comes from iron oxides found in deposits such as massive hematite (the most commonly mined), magnetite, titanomagnetite, and pisolitic ironstone.

How Iron Was Made
Using the ancient "bloomery" method, iron ore was converted directly into wrought iron by heating the ore while at the same time melting the ore's impurities and squeezing them out with hand hammers. This is also called the "direct process." By the 1100s water-powered hammers replaced hand hammers for forging out bars of iron.

Iron Ore Processing: From Extraction to Manufacturing
The final stage in iron ore processing is ironmaking, where the iron ore is transformed into molten iron through a process called reduction. The most common method of ironmaking is the blast furnace route. In a blast furnace, iron ore, coke (carbon), and fluxes (limestone or dolomite) are loaded into the furnace from the top.
