Iron Ore: The Steel Raw Materials Journey | MachineMFG
Theoretically, the highest iron content in iron ore is around 72%, and iron ore with an iron content above 60% is called rich iron ore. Iron ore is first reduced to iron (pig iron) in a furnace, then sent to a steel-making furnace for decarburization and refined into steel. Scrap steel can also be melted and regenerated in a steel-making furnace.

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.
