The current method for processing iron ore is by melting it in a blast furnace, causing the iron oxide to separate from the other parts of the ore. Hot oxygen interacts with coal in the furnace to create carbon monoxide (CO), which then interacts with the iron oxides, taking up the oxygen to become carbon dioxide (CO 2 ), and leaving plain iron ...

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 ...
