Electrowinning, also called electroextraction, is the recovery of metals from solutions through the use of electrolysis. All over the planet metals are being dissolved in solutions for processes ranging from plating to anodizing to refining and more.
Solvent extraction is used to concentrate materials in an organic solution, while electrowinning is used to recover these pay elements. The two procedures are often conducted together. While electrowinning can be used with other processes, it is always used after solvent extraction.

An electrowinning unit has three main components: 1) electrolytic cell; 2) rectifier; and 3) pump. An electrolytic cell is a tank in which cathodes and anodes are typically arranged in alternating order (Fig. 1). The cathodes and anodes are attached to their respective bus bars, which supply electrical potential to the unit.

Thus, in a batch electrowinning operation the acid concentration will increase (ie. the pH will drop) as the electrowinning process proceeds. In the case of nickel electrowinning, metal deposition may be ktitiated but will quickly yield to hydrogen production as the pH of the solution drops.

Any non-adherent solids which tend to accumulate during the electrowinning process are swept to the cell bottom and contained for convenient draining (the electrodes are raised 3″ above the cell floor to eliminate the possibility of the solids causing a short circuit).
An additional benefit of silver recovery with emew® electrowinning is that the electrowinning cell doesn’t have to be opened in order to harvest the metal. Silver will have a powdery form and the deposit is automatically flushed out of the cell to a secure collection vessel.

3). Thus, the gold particles are in electrical contact with that electrode. Since secondary electrowinning may also be carried out simultaneously in that cell, the gold from both sources is effectively combined at the cathode. However, initially the EWEF cell was used on its own to electrowin gold from original and diluted eluate solutions.
The Allglass Australia electrowinning cell design operates at recovery efficiencies of up to 99 per cent in one pass and can operate with eluate derived from either AARL or ZADRA elution systems.

Electrowinning is the recovery of metals, such as gold and silver, from solution by passing a current through the solution. Electrons from the current chemically reduce the gold and/or silver ions, to form a solid metal compound on the cathode.
Electrowinning and smelting are the final stages of gold production. The concentrated gold solutions produced in the elution circuit (pregnant eluate and by the Sunrise Reactor, are passed through the electrowinning cells which converts the gold ions (charged gold particles) in the solution into solid gold.

I think the better way is carbon adsorption of pregnant liquids before electrowinning , by simple activated carbon in column CIC. So you can concentrate gold and copper into the activated carbon, then you can easily make two stages of desorption, first with cold cyanide solution for copper recovery, and then with other hot cyanide desorption ...
