Practice questions for Extracting Metals
Which method is used to extract a metal that is MORE reactive than carbon?
Iron is extracted from haematite in a blast furnace. Describe how iron is obtained from iron oxide using carbon, and explain the term 'reduction' in this context.
Quick recall flashcards
Which metals must be extracted by electrolysis, and why?
Metals MORE reactive than carbon (e.g. aluminium, sodium, potassium) must be extracted by electrolysis. Carbon is not reactive enough to pull oxygen away from them.
What is haematite, and where is iron extracted from it?
Haematite is iron oxide (Fe₂O₃) — the main ore of iron. Iron is extracted from haematite in a blast furnace using carbon (coke) as the reducing agent.
