Hydrometallurgy is a broad field of science and technology that relates to the recovery of metals via processing in waterbased solutions. The recovery of gold by cyanidation, copper by heapleachSXEW, zinc by roastleachelectrowin or pressure leaching are all examples of hydrometallurgical technologies that are practiced globally.

Hydrometallurgy has evolved, both as an alternative to and a complementary method for the pyrometallurgical recovery of metals. It eases the recovery of value metals from ores containing impurities that can produce highmeltingpoint slags.

Copper hydrometallurgy is a branch of metallurgy method to extract copper directly from those difficulttoconcentrate copper oxide ore. Traditional copper hydrometallurgy process typically consists of atmospheric leaching, solvent extraction (SX) and electrowinning (EW).

Hydrometallurgy 2 Leaching Processes covers the leaching processes used for hydrometallurgical treatment of mineral ores, concentrates and metals. It covers treatment of the ore types and metals susceptible to hydrometallurgical treatment, from precious metals to oxides, hydroxides, sulfides, phosphates, silicates and others. Content

A method is provided for extracting copper, cobalt and zinc from an ore containing those metals and manganese dioxide. The ore is subjected to an acid, oxidizing leach followed by an acid, reducing leach. Solids are separated from the leachate and the leachate liquid is subjected to solvent extraction steps, to sequentially remove copper, zinc and cobalt in that order.

The precipitation of copper on iron from natural solution is a classical example of a relatively ancient art which has been applied successfully for centuries to produce copper on a commercial scale. The method applied to extraction of copper from mine water has been practiced in China since 1086, in the Northern Sung period (960–1126 ).

The most commonly used route in the hydrometallurgical extraction of zinc and copper from a sulphide ore is the concentrateroastleachelectro winning process. In the present investigation a...

Hydroxyoximes and Copper Hydrometallurgy provides a current examination of what is known regarding hydroxyoxime extractants, the chemistry and physicochemistry of extraction, and the potential of applying hydroxyoximes for extraction of copper and other metals in industrial processes.
