copper electrowinning process

PDF	Copper electrowinning: theoretical and practical design The procedure provides a means of linearizing the relationship between overpotential and current or rate of reaction Mass transport The movement of species

What is the process of copper electrolysis?
Electrolysis uses an electrical current to move ions in an electrolyte solution between two electrodes.
In copper electrolysis, when a current is applied, positively-charged copper ions (called cations) leave the anode (positive electrode) and move toward the cathode (negative electrode).
What is the process of copper solvent extraction and electrowinning?
Solvent extraction and electrowinning (SX/EW) is a two-stage hydrometallurgical process that first extracts and upgrades copper ions from low-grade leach solutions into a solvent containing a chemical that selectively reacts with and binds the copper in the solvent.
What is the process of electrowinning?
Electrowinning (or electroextraction) is a process of whereby metals, such as gold, silver and copper,are recovered from a solution by means of electrolytic chemical reaction.
This takes place when an electric current is passed through the solution.
2H2O + 2CuSO4 = 2Cu0 + O2 + 2H2SO4(a).
Copper electrowinning circuit of a plant having L/SX/EW configuration and using permanent cathode technology consists of a stainless steel cathode, an inert anode (lead alloy), and the copper electrolyte that contains Cu+2, Fe+3, Fe+2, Co+2, and SO4-2 as major elements.
