1. Extracting Iron

2. Starter Activity What is the sentence?
from the
-m +n is
Cast iron right from the blast furnace is brittle and very hard
&
-die

3. Extracting Iron Learning Objectives:
Describe what happens in the blast furnace
Write word equations for the reactions that take place inside the blast furnace
Explain why most iron is turned into steel

4. Extracting Iron Iron ore Iron is LESS reactive than carbon
Haematite
Fe2O3
Iron is LESS reactive than carbon
Reduction using carbon is used
This process takes place in the blast furnace

5. Video
Watch the video and complete the video worksheet

6. Mini Plenary
Write down two things you know now that you know now that you didn’t at the start of the lesson

7. The reactions The coke burns C + O2  CO2
The limestone is thermally decomposed
CaCO3  CaO + CO2
The carbon dioxide reacts with more coke
CO2 + C  2CO

8. The reactions
The carbon monoxide reduces the iron ore to iron metal. This is a liquid and runs to the bottom of the blast furnace
Fe2O3 + 3CO  2Fe + 3CO2
The calcium oxide combines with the sand to form the liquid slag which floats on top of the liquid iron.
CaO + SiO2 CaSiO3

9. Practical task
We are going to under take an experiment to extract iron.
