Extracting Iron

Question 0

What happens in the actual process?

Answer 0

1) hot air is blasted in to the furnace making the coke burn much faster than normal. This raises the temperature to around 1500 degrees centigrade
2) the coke burn producing carbon dioxide
Equation- C + O > CO(2)
3) the CO(2) reacts with the unburnt coke to form carbon monoxide
Equation- CO(2) + C > 2CO
4) the carbon monoxide then reduces the iron ore to iron
Equation - 3CO + Fe(2)O(3) > 3CO(2) + 2Fe
The iron is molten at this temperature.
