The feasibility of elution with simultaneous electrowinning was demonstrated in the laboratory. Complete elution and gold recovery were achieved in less than 5 h, with an average current efficiency of about 50%. Present address: Sastech Engineering Services, Private Bag X1034, Secunda, 2302, South Africa.

2016-1-1 Electrowinning is most often used to recover gold and silver from eluates produced by the elution of activated carbon. Some of the practical considerations involved in the design and operation of gold electrowinning cells are described in this chapter, including cell types, bullion removal, and special applications such as electrowinning from gravity concentrates, and sulfide oxidation filtrates.

The wash solution—pregnant electrolyte—is passed through electrowinning cells where gold and silver is won onto stainless steel cathodes. See more detail on elution and electrowinning. 7. Bullion production The loaded cathodes are rinsed to yield a gold and silver bearing sludge which is dried, mixed with fluxes and put into the furnace.

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.get price

The plant was experiencing problems in the leach, adsorption, elution and electrowinning sections mainly as a result of the presence of copper in the ore. The changes made to the operating standards, the response of the circuit to these changes and the final Circuit layout and operating conditioning resulting in a 90% gold recovery are discussed.

Gold Fields installed what was the mining industry’s first commercial gold electrowinning/replate circuit at Ortiz in 1981. Its highly successful operation since that time provided the design basis for a similar circuit at Mesquite, which was started in early 1986. These circuits produce plated gold foil suitable for direct shipment to a refinery or melting directly into bars. Detailed ...
