Electrowinning | Gekko
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 - an overview | ScienceDirect Topics
Electrowinning has proved to be an effective and simple method for recovering gold from the eluate. Electrowinning is done simultaneously with the elution. The barren eluate is recycled to the eluant tank and is recycled for the next elution after the reagents have been made up to their relevant concentrations.
Electrowinning 101: What is electrowinning?
Electrowinning is a widely used technology in modern metal recovery, mining, refining and waste water treatment applications. Electrowinning is one of the oldest electrolytic processes known and was first introduced in 1807 by English chemist Humphry Davy.After 66 long years the first commercial refinery Balbach and Sons Refining and Smelting Company adopted the electrowinning technology and ...
Electrowinning and Smelting - Resource Book
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 - an overview | ScienceDirect Topics
Electrowinning is the process of “winning” metal from solution using an applied voltage. Gold electrowinning is usually performed in relatively small vessels or cells that are about 1 m long and contain less than 1 m 3 of solution. These cells often contain several cathodes and anodes, although there is one extra anode.
Electrowinning - Metallurgist & Mineral Processing …
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.

Electrowinning - Wikipedia
Most metals occur in nature in their oxidized form (ores) and thus must be reduced to their metallic forms. The ore is dissolved following some preprocessing in an aqueous electrolyte or in a molten salt and the resulting solution is electrolyzed. The metal is deposited on the cathode (either in solid or in liquid form), while the anodic reaction is usually oxygen evolution. Several metals are naturally present as metal sulfides; these include copper, lead, molybdenum, cadmium, nickel, silver, cobalt, and zinc. In addition, gold and plat…

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, stone ...
