Elution is the next step in the process, whereby the adsorption of the goldplex 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
The gold is then stripped from this loaded carbon by means of elution to form a concentrated eluate which is then processed for gold recovery by electrowinning. Essentially elution is the reverse of the adsorption process.
The gold can then be desorbed from the loaded carbon in a process known as elution this step is often referred to as stripping, which produces a high gold concentrate solution from which gold can be electrowon. Characteristics of Activated Carbon for Gold Recovery. Various types of activated carbon exist, even within the field of gold recovery.

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
Gold Elution Plant Gold plant will be that of the leaching and carbon in pulp circuit cip. the reagent and utilities operating costs associated with leaching, adsorption, elution and regeneration would typically make up some 15 of total operating cost, whilst the capital costs
All of the stripping operations are carried out at 5560 °C and atmospheric pressure. The original design of the stripping section required up to 288 h 12 days for elution before achieving gold recovery. In the 1980s, a new stripping technique was developed, which takes from 12 to 24 h, a considerable improvement over the original design.
