The Mining Process – Waihi GoldA slurry of ground ore, water and a weak cyanide solution is fed into large steel leach tanks where the gold and silver are dissolved. 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.
AARL Carbon Stripping System Operation: Elution ...During this stage a 2% caustic/3% cyanide solution mixture is re-circulated through the loaded carbon in the elution column until such time as a predetermined "top of column" temperature is reached. By this time most of the gold and silver on the carbon will have been desorbed into solution and both the carbon and the solution will have reached an optimum temperature for the subsequent ...
Elution - an overview | ScienceDirect TopicsElution of AM-2B resin is similar to that of Minix; but a longer elution time seems to be required (Bolinsky and Shirley, 1996).The process includes a series of elutions, contacting the loaded resin with different solutions. The elution flowsheet differs from plant to plant, .

Carbon Stripping – Denver Mineral Engineerscarbon as a sodium or calcium/gold cyanide ion pair (2) is desorbed from the carbon by a reversal of the adsorption kinetics. Gold is recovered from the pregnant strip solution by electrowinning onto steel wool. The gold depleted solution is then reheated and recycled to the carbon bed for reuse (see Figure 1).

Extracting Gold | HowStuffWorksRemoving the gold-bearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to ...
Elution - WikipediaThe "elution time" of a solute is the time between the start of the separation (the time at which the solute enters the column) and the time at which the solute elutes.In the same way, the elution volume is the volume of eluent required to cause elution. Under standard conditions for a known mix of solutes in a certain technique, the elution volume may be enough information to identify solutes.

Sabinet | The elution of gold from activated carbon at ...One of the main bottlenecks in the carbon-in-pulp process for the recovery of gold is the elution procedure, which typically requires the heating of caustic cyanide eluants to high temperatures for 16 to 24 hours. The present work demonstrates that sodium sulphide solution as an alternative eluant can effect complete elution in about 4 hours at ambient temperatures.
