Methods of extraction Many metals are found in the Earth s crust as ores An ore is usually a compound of the metal mixed with impurities When the metal is dug up a method must be used to separate the metal from the rest of the ore This is called extracting the metal The method of extraction depends on how reactive the metal is The more reactive the metal the more difficult it is to
