Iron Ore Refining Process

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

Steelmaking and Refining Introduction to Chemistry

The pig iron was melted in a running-out furnace and then run out into a trough. This process oxidized the silicon to form a slag, which floated on the iron and was removed by lowering a dam at the end of the trough. The product of this process was a white metal known as finers metal or refined iron.
