The StepbyStep Process of Producing Iron from Iron Ore
The raw materials mix or "charge" enters the furnace from the top and hot air is blown or blasted from the bottom causing the coke to burn and the oxygen to combine with carbon in the coke to form carbon monoxide. Now this carbon monoxide that is unstable reacts with the ore to form carbon dioxide and iron. The Separation Of Iron.
