Iron oxide is heated in an intense flame fed by carbon fuel. Oxygen in the ore combines with carbon monoxide released from the fuel and is expelled as CO 2. What is left is iron. The blast furnace's height lets the rising gases preheat the ore and gives the iron more distance to descend as it softens – so it absorbs more carbon from the fuel.Web
