Home → 50.5 EXTRACTION OF METALS METALLURGY . As already mentioned only a few most unreactive metals occur in nature in free state. Most of the metals occur in nature in oxidized form as their compounds. Therefore, metals are generally extracted by subjecting their ores to reduction by chemical methods or by electrolytic methods.

Mining and ore processing occurs throughout the world and consists of extracting minerals, metals, and gems from surrounding earth and ore. Industrial mines vary in size, with some being quite small operations and others very large. Many large scale mines also have ore processing facilities where extracted ore is sent for crushing, washing, and various physical or chemical separation
Most metals must be extracted from rocks, called ores, in the Earth's crust. Ores contain the metal, or a compound of the metal, in a high enough concentration to make it worth extracting the metal
Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy. The
