Extracting Metals

Question 1

How can carbon be used to reduce an ore?

Answer 1

If a metal is less reactive than carbon, it can be extracted from its oxide by ‘HEATING WITH CARBON’. The carbon displaces the metal from the compound, and removes the oxygen from the oxide. This leaves the metal.

Question 2

What’s the other way to extract metals which are more reactive than carbon?

Answer 2

Electrolysis
