metallurgy and hydrometallurgy copper - Industrial ...

This process consumes 2,500 to 3,000 kWh · t –1 of copper produced. The copper is deposited on the cathode and the gases produced at the anode (O 2, Cℓ 2) are recovered selectively and returned to the process. This method produces an extremely pure copper that can then be rolled (hot or cold), drawn or even formed into tubes before being sold.

WO2003038137A1 - Recovery of copper from chalcopyrite ...

A process for recovering copper from chalcopyrite is disclosed. The process includes oxidising sulphur in chalcopyrite with a solution under predetermined contact conditions and thereby releasing at least part of the copper in the chalcopyrite into the solution as copper ions. The process includes a subsequent step of reducing sulphur in a solid product from step (a) to a …

Pyrometallurgy | Hazen Research

Pyrometallurgy. The basic premise of most pyrometallurgical operations is simple: high-temperature chemistry is employed to segregate valuable metals in one phase while rejecting gangue and impurities in another phase. In most instances, both phases are molten (such as the matte and slag in a conventional copper smelting operation).

Refining – Various Methods

Therefore it becomes easier for separating the pure metal from the impurities. Usually, the entire process is conducted in a sloped container; hence the liquid metal runs down while the solid impurities stay behind in the container. Earlier it helped to separate silver from copper using lead as a solvent. Still, this method helps in refining tin.
