  • How Are Metals Extracted From Their Ores? Reference

    Metal extraction from ores occurs in many different ways involving physical, chemical and electrical means. Even ores of the same metal sometimes require different methods of separation depending on the concentration of the metal and its chemical composition within the ore. Ores are naturally occurring sources of metal.

    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
