Extraction of Iron: Meaning, Purification, & Extraction …
Iron is extracted from its ore (haematite, Fe₂O₃) in a blast furnace. The ore is mixed with limestone (CaCO₃) and coke (a form of carbon) and heated to very high temperatures. Coke burns to produce heat and reduces the iron ore to iron, releasing carbon dioxide.

Iron Ore Facts
Iron ore is rock which metallic iron can be extracted from. Iron ore is the most common element in the world and makes up close to 5% of the Earth's crust. This makes it one of the most abundant rock elements. Iron ore that contains a high quality of hematite or magnetite are known as "natural ore" and they can be entered directly into blast furnaces that produce iron.
