Copper Electrowinning Process

Copper electrowinning is based on the copper electrolysis principle which uses electrical power to reduce copper ions in solution to the copper metal on the cathode and to oxidize water on the anode in oxygen gas and hydrogen ions. The chemical equation (a) gives the copper electrolysis global chemical reaction. 2H2O + 2CuSO4 = 2Cu0 + O2 ...

Electrowinning is a process used to remove metal ions from liquid solutions such as rinse water, plating baths, and used process solutions. Most often used to recover precious metals, it relies on an electronic current to plate the metal ions onto a cathode. Recovered metals can then be sold for scrap or processed for use in plating.

Solvent extraction equipment consists of a series of mixers and settlers. Here's where the mixers receive the solvent from a previous settler in the process. This would be an aqueous solution: either a leach solution or electrolyte from the electrowinning process. The two solutions are mixed then discharged by overflow to the adjoining settler.


Stainless steel cathodes become coated in copper during the electrowinning process. Copper is stripped from the steel cathode plates when it is thick enough. This cathode copper is 99.99% pure. Solvent Extraction and Electrowinning (SX-EW) production, virtually non-existent before the 1960s, reached nearly 3.8 million tonnes of copper in 2013 ...


Copper hydrometallurgy is a branch of metallurgy method to extract copper directly from those difficult-to-concentrate copper oxide ore. Traditional copper hydrometallurgy process typically consists of atmospheric leaching, solvent extraction (SX) and electro-winning (EW). It can produce either copper cathode or copper sulphate crystal.


A nickel electrowinning process carried out in a bag-free cell characterized by maintaining the electrolyte at a temperature in excess of 60°C and a pH of about 1.5 to 2.0 and feeding pregnant electrolyte to and withdrawing spent electrolyte from the cell to maintain a nickel bite of at least 5 grams per liter while operating at relatively high current densities.


Electrowinning is a manufacturing process for making metals from a solution containing dissolved metal. The process involves passing an electrical current from an inert electrode through the solution containing the metal, to plate the metal to another electrode. Also called electroplating, it is a common process for producing metals like copper, cobalt, nickel, zinc, aluminum, and gold among ...

Electrowinning - Wikipedia

Electrowinning is defined as the cathodic deposition of metal, in this example copper, from a copper bearing solution by the passage of an electric current current using an insoluble anode.. For copper the electrowinning reaction reaction is: CuSO4 + H2O ⇒ Cu + ½O2 + H2SO4. The overall reaction is the combination of two electrochemical half reactions.
