    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.

    A copper ore is a mixture of copper minerals and other materials in the rock called gangue, from which it is economically viable to extract the metal. A typical copper ore contains between 0.5% and 2.0% copper. A high grade ore produces a high yield of metal. A low grade order produces a low yield of metal.
