How is iron ore processed to steel

Iron ore, as mined, is a combination of iron with oxygen and various other unwanted substances, generally known as gangue . The first metallurgical step is to reduce iron ore to metallic iron, a process which is mostly carried out in a blast furnace, using coke as both a fuel and reducing agent

    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
