Thus, hydrometallurgy is the study of water and metals. Most metal production includes some hydrometallurgical processing to obtain a finished metal product. Many metals can be produced by hydrometallurgical processing from minerals. Some metals, such as copper and gold can be processed from crushed ore to purified metal using hydrometallurgy.

Article By Gary Carter. Photos sourced by Western Mining History. Numerous articles and books have described the techniques to extract valuable metals from waste rock. One of the best books on the subject is Drills and Mills by Will Meyerriecks. Meyerriecks describes the process of extracting metals from waste rock as "winning the metal".
