Extraction of Metals

• metals are found in earth as ores. They are unpure and is basically an oxidised metal.
•  carbon reduction 

  In these reactions, the metal ores will be reduced and the carbon will be oxidised.
• product formed by carbon reduction?

  metal ore loses oxygen whilst the carbon gains oxygen, forming carbon dioxide.
• Carbon reaction can only occur when the metal is lower in the reactivity series.
• Electrolysis


  good alternative to carbon reduction but is expensive.
