    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

    There are 3 main methods of extracting metals from their ore. They are reduction of the ore with carbon, reduction of the molten ore by electrolysis, and reduction of the ore with a more reactive metal.

    Overview of the different methods of extraction of

    In order to extract a metal, the ore or compound of the metal must undergo a process called reduction to free the metal (i.e. the positive metal ion gains negative electrons to form the neutral metal atom, or the oxide loses oxygen, to form the free metallic atoms).

    The Impact of Metal Extraction to the Environment,

    Now, the methods of extracting metal do not come cheap, nor does refining and purifying metal. Not only will you need special equipment for their extraction, but you will also need other elements as well such as copper, zinc, mercury, among others, for the purification and refinement processes.
