Reducing the Iron Ore to Iron:

Question 1

What is done first? (Hot)

Answer 1

Hot air is blasted into the furnace, making the coke burn much faster than normal - raises temp to about 1500°C

Question 2

2) what does the coke do?

Answer 2

Burns and produces carbon dioxide

C + O2 —> CO2

Question 3

3) what does the CO2 do?

Answer 3

Reacts with unburnt coke to form CO

CO2 + C —> 2CO

Question 4

4) what does the carbon monoxide do?

Answer 4

Reduces the iron ore to iron

3CO + Fe2O3 —> 3CO2 + 2Fe

Question 5

What is the iron like at this temp?

Answer 5

Molten and very dense, so runs straight to the bottom of the furnace where it’s tapped off

Question 6
