Apr 17, 2017· Electrowinning processes can also be used for wastewater treatment and general recycling. The principle is still the same, any impure material can be leached into a conducting solution, then the DC voltage is applied through the solution and the desired material can be extracted (of course, there are certain limitations such as metal concentration, temperature, acidity levels, chemical ...
Electrowinning is a process used to recover metals (eg. gold and silver) from concentrated solutions by applying a voltage across electrodes immersed in a concentrated solution. The positive terminal from the rectifier is connected to the anode where the oxidation reactions occur and electrons are generated.

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.
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.
