Iron is one of the most abundant elements on Earth, but in its natural state is bound to oxygen in the various minerals that make up iron ore. To extract metallic iron from this ore, workers typically mix it with a high-carbon form of coal called coke and heat the combination to about 1500°C in a blast furnace. At that temperature, the carbon ...
