What is extraction of iron in the blast furnace?Show answer
Iron is below carbon in the reactivity series, so it is reduced by carbon in a blast furnace. The raw materials are iron ore (haematite, iron(III) oxide), coke (carbon) and limestone (calcium carbonate), with hot air blasted in. The key stages:
What is q1?Show answer
State the method used to extract a metal that is more reactive than carbon. [1 mark]
What is q2?Show answer
Name the three solid raw materials added to a blast furnace. [1 mark]
What is q3?Show answer
Explain why carbon can be used to extract iron but not aluminium. [2 marks]
