Iron ore contains iron oxides, and when it is heated with coke (essentially carbon), oxygen moves from the oxides to the carbon, reducing the ore to molten iron. In the 19th century Britain smelted iron from lumps of iron ore, using blast furnaces fuelled by coke. In this process, molten iron from the ore forms a pool at the base, and is poured ...

Iron ore is a rock or mineral from which metallic iron can be extracted economically. It constitutes 5% of the earth's crust. Viable forms of ore contain between 25% and 60% iron. Ore greater than 60% iron is known as natural ore or direct shipping ore, meaning it can be fed directly into iron-making blast furnaces.
