# Iron is extracted from its ore using reduction with carbon in a blast furnace. Explain why this method can be used to extract iron, and describe what happens chemically during the extraction process.

> Edexcel GCSE Chemistry (1CH0) — 4.1 Obtaining and using metals · Explain · 4 marks

## Mark scheme (4 marks)

1. Iron is less reactive than carbon (so carbon can displace/reduce it)
2. The iron ore (iron oxide) is heated with carbon
3. Carbon reduces the iron oxide / the iron oxide loses oxygen
4. Iron (metal) is produced / carbon is oxidised (gains oxygen to form carbon dioxide or carbon monoxide)
