Extraction of metal from an ore depends on the place it has in the reactivity series. Following points explain this. Metals found at the bottom of reactivity series are least reactive and they are often found in nature in free-state, such as gold, silver, copper, etc. Copper and silver are also found in the form of sulphide and oxide ores.

Reduction of Metals Extraction from Ore ALevel Chemistry

Extraction using carbon. Metals such as zinc, iron and copper are present in ores as their oxides. Each of these oxides is heated with carbon to obtain the metal. The metal oxide loses oxygen, and is therefore reduced. The carbon gains oxygen, and is therefore oxidised. If playback doesnt begin shortly, try restarting your device.
