How is Iron Refined from Ore with pictures

How Is Iron Refined From Ore With Pictures

Iron ore consists of oxygen and iron atoms bonded together into molecules. To create pure iron, one must deoxygenate the ore, leaving only iron atoms behind, which is the essence of the refining process. To purify and strengthen iron, materials like coke are mixed in with it to remove oxygen. To coax the oxygen atoms away from the ore requires ...
