Iron ore is mixed with coke, a form of very pure coal. The blast furnace burns the coke to heat the iron ore causing it to react into iron (Fe 2), nitrogen (N 2), and carbon dioxide (CO 2). This iron is often known as "pig iron" or "hot metal" as it is a liquid iron that flows from the bottom of the blast furnace.
