Iron ores in the form of hematite (ferrous oxide) and magnetite are removed from the earth through mining. The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore; however, because iron does not occur naturally, it is necessary to use a blast furnace to separate or refine iron from the other substances in the …

Iron is an element that has the chemical symbol, Fe. It is a metal that has been used since prehistory, by the Ancient Egyptians and Sumerians as early as 4000 B.C. These ancient peoples were able to get pure iron from meteorites that fell to the earth, and they used it in the tips of weapons and spears because of its strength and durability.

1) Hot air is blasted into the furnace, making the coke burn much faster than normal. This raises the temperature to around 1500C. 2) Coke burns and produces carbon dioxide: C + O2 --> CO2 3) The carbon dioxide then reacts with the unburnt coke to form carbon monoxide: CO2 + C --> 2CO 4) The carbon monoxide then reduces the iron ore to iron: 3CO + Fe2O3 --> 3CO2 + 2Fe …

Hematite (Fe₂O₃): Contains about 70% iron and is one of the primary ores used in iron extraction. Magnetite (Fe₃O₄): Contains about 72% iron and has magnetic properties. Limonite (Fe₂O₃·nH₂O): A hydrated form of iron oxide, usually less rich in iron. Siderite (FeCO₃): Contains about 48% iron and is less commonly used because it's harder to process.
