DRI production | International Iron Metallics Association

DRI production. Direct reduction of iron is the removal of oxygen from iron ore or other iron bearing materials in the solid state, i.e. without melting, as in the blast furnace. The reducing agents are carbon monoxide and hydrogen, coming from reformed natural gas, syngas or coal. Iron ore is used mostly in pellet and/or lumpy form.

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 ...
