Refining processes extract valuable metals from ores or other raw materials. Refining refers to any process that increases the grade or purity of a metal. Smelting is known to be a major cause of pollution in the environment. The smelting of sulphide ores produces sulphur dioxide gas and is emitted into the atmosphere.
