Iron Extraction - W3spoint

The common ores of iron are its oxide, hematite, Fe 2 O 3, and magnetite, Fe 3 O 4. They can be reduced to iron by heating them with carbon in the form of coke. The coke burns in an exothermic reaction. At the high temperatures, the carbon dioxide reacts with more coke to make carbon monoxide. The carbon monoxide REDUCES the iron oxide in the ore, into molten iron which flows to the bottom
