Hydrometallurgy is a method for obtaining metals from their ores. It is a technique within the field of extractive metallurgy involving the use of aqueous chemistry for the recovery of metals from ores, concentrates, and recycled or residual materials. Metal chemical processing techniques that complement hydrometallurgy are pyrometallurgy, vapour metallurgy and molten salt electrometallurgy.

The development of ion exchange, solvent extraction, and other processes has led to an extremely broad range of applications of hydrometallurgy, now used to produce more than 70 metallic elements. Besides most gold and much silver, large tonnages of copper and zinc are produced by hydrometallurgy.

cation of the copper-selective solvent LIX4. 5,eventhough used in the treatment ofoxide ores, provided the most significant breakthrough in copper hydro-metallurgy sincethat achieved by Sherritt Gordon intheir success-ful development of pressure-leaching techniques.
