electrowinning process of gold from elution circuit

Electrowinning and Smelting Resource Book

2010-7-14  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. The process of electrowinning simply involves passing an electric current through the electrolyte (eluate).

The Mining Process Waihi Gold

Following this leaching process the slurry passes through six adsorption tanks containing carbon granules which adsorb the gold and silver. This process removes 93% of the gold and 70% of the silver. See more detail on leaching and adsorption. 6. Elution and electrowinning The loaded carbon is fed into an elution column where the bullion is

Elution and Carbon Reactivation Resource book

2010-7-14  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). The gold can then be removed from the

The process design of gold leaching and carbon-in-pulp

2009-8-27  reversal of the adsorption process with most of the gold desorbing from the carbon back into solution. This produces a small volume of solution with a high gold concentration. The gold is recovered from this solution by electrowinning, zinc precipitation or refining technology such as the Mintek Minataur process.

Endeavour Reports Positive PFS Results For Both

2021-2-23  The leached gold solution will be processed in seven carbon-in-pulp tanks before gold is recovered from loaded carbon in a AARL elution circuit, electrowinning and gold smelting to

Ore processing Waihi Gold

In contrast, by the time the carbon reaches the first adsorption tank it has recovered most of the gold and silver from solution. 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).

Northern Star South Kalgoorlie

A split Anglo-American Research Laboratories process is utilised where the gold laden carbon is first acid washed, and then eluted in a column using hot caustic cyanide solution. At the completion of the elution step the barren carbon is sent to the kiln for regeneration prior to being returned to the adsorption circuit.
