· Gold is recovered from the pregnant eluant by electrowinning and the barren eluant is discarded See Figure 3. After rinsing the carbon is pressure transferred to the elution column. Continued research at the USBM revealed that the Zadra process stripping rate could be increased greatly by stripping at higher temperatures 4. This is due to its ...
Electrowinning, also called electroextraction, is the electrodeposition of metals from their ores that have been put in solution via a process commonly referred to as leaching. Electrorefining uses a similar process to remove impurities from a metal. Both processes use electroplating on a large scale and are important techniques for the economical and straightforward purifiion of non ...
· An example of the appliion is planned by Condor Gold at its openpit La India GoldSilver Project in Nicaragua. There, gold from loaded carbon will be recovered in an elution circuit and then forwarded to electrowinning and smelting processes to produce dore bar.
Elution is the next step in the process, whereby the adsorption of the gold cyanide complex onto carbon is reversed. Loaded carbon is removed from the CIL circuit and the gold stripped from the carbon using a number of treatment steps. The result is a solution of high gold concentration (pregnant eluate).

This gold electrowinning plant was designed and manufactured by SX Kinetics for a customer in Bolivia. This small plant is for the production of 5 kg of gold per week from carbon elution. The electrowinning plant included the electrolyte tanks, electrolyte pumps, the electrowinning cell, heat exchanger, circulation heater and rectifier. The plant is connected to a carbon elution circuit and it ...

The gold in Kalgoorlie ore occurs in several different forms, each requiring ...
This 'loaded' carbon is then pumped to the elution circuit (6) where the gold and silver is washed off with superheated water. The washed solution, called pregnant eluate, is passed to the electrowinning circuit (7). The remaining barren carbon is reactivated by acid washing and kilning and returned to the adsorption tanks (8).
· Outotec launches Elution and Goldroom plant. August 19, 2021. August 19, 2021. Janet. Finnish mining engineering firm Outotec has launched a compact new electrowinning gold recovery solution called the Elution and Goldroom plant. The new plant offers a standardised solution for the forming of concentrated eluate, said the company.
· The Elution and Goldroom plant is the final step in the gold process flowsheet, where the gold cyanide complex is desorbed from the activated carbon, recovered as a metal in the electrowinning cells, and refined to doré gold bars in the gold room. The activated carbon is regenerated for reuse in the cyanide leaching section.
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.
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 ...
A short video of Henty Gold Mine's processing plant elution circuit where the gold is recovered from the loaded carbon after leaching. Get Price; Gold Recovery Systems Macrotec. During the gold mining elution process, activated carbon that is deemed too fine for reuse is removed. Since these fine carbon residues contains on average between 100 to 400 grams of Gold per ton it makes a easy ...
Optimizing the operating conditions of gold elution and ...
Gold Solvent Extraction / Reduction Process Most of the world's gold production uses cyanide leaching followed by carbon adsorption and electrowinning because it has proven to be the best technological, environmental, and economical process for the recovery of gold from a wide variety of ores. The process consists of leaching the gold with dilute sodium cyanide and sodium hydroxide solution ...
· With the AARL process, elution is normally proceeded by acid washing the carbon. Over the elutio year the gold extracted has averaged approximately 60 kg per day on a day per year basis. The process is still widely used today because of its simplicity. The solution is then discarded.
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.
