Copper removal from industrial wastewater: A
25.12.2017· Physico-chemical treatments can be considered to be the most suitable treatment methods for the removal of copper ions from industrial wastewater. However, they still suffer from high operating cost due to the high cost associated with the chemicals used and high energy consumption. Since metal-contaminated wastewater may contain some inorganic and organic matters,

metallurgy and hydrometallurgy copper -
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. Wastewater treatment is extremely important in these factories. It includes:
