Copper extraction techniques refers to the methods for obtaining copper from its ores. ... a process called cementation. Cement copper is normally less pure than SXEW copper. Commonly sulfuric acid is used as a leachant for copper oxide, although it is possible to use water, particularly for ores rich in ultrasoluble sulfate minerals ...
In cementation, the acidic solution of copper is deposited on to scrap iron in an oxidationreduction reaction. After sufficient amounts of copper have been plated, the copper is further refined using the pyrometallurgical process. However, this process is rarely used. Solvent extraction is more commonly used to refine copper.

An electrochemical study of gold cementation with zinc powder at low cyanide concentration in alkaline solutions ... tice, where high concentrations of silver or copper are found, zinc cementation is preferred over the other two processes [3].
Another object of this invention is to provide a process for the simultaneous leaching and cementation of precious metals such as gold and silver. Another object is to provide an improved method for the recovery of precious metals from refractory carbonaceous ores.
Definitions Description of Copper Based Products ... Copper is recovered from its sulphide ores by a dry extraction process in which the powdered and concentrated ore is roasted where necessary to drive off excess sulphur and smelted in a furnace to produce copper matte. ...

It was found that N1932 is the main extractant with TBP as a synergistic reagent at pH <9, while N1932 shows a synergistic effect on the extraction of gold with TBP at pH >9. In summary, our results have shown that zinc cementation is a better choice. However, all pilot tests used the copper cementation process.
