5.4.2 Reactivity Series and Extraction of Metals
1. The method that is used in the extraction of metal from its ore depends on the position of
the metal in the reactivity series of metals.
 



2. Metals which are located higher than carbon in the reactivity series are extracted from
their molten ores using the electrolysis method.
3. Metals which are located lower than carbon in the reactivity series are extracted using
the reduction method with coke (or carbon).
4. Carbon is used in the extraction process because
(a)  It is cheap
(b)  Easily obtained
5. Metals located the lowest in the reactivity series like silver and gold can be extracted
naturally without any complex chemical reaction. These metals exist as free elements in
the Earth’s crust.
