  • Elution and Carbon Reactivation - Resource book

    conditions, elution (desorption) of gold from the carbon occurs. The main factor that makes desorption or stripping a simple process is the fact that gold will only adsorb onto carbon at low temperatures. If the temperature of a solution and carbon mixture is increased, the gold will readily desorb from the carbon into the solution. Temperature

    Elution stage. During this stage the gold and silver desorbed off the carbon during the ‘preheat .* is washed out of the column into the eluate tank. This stage takes 2 1/2 hours and involves the use of 5 bed volumes of potable water (21.6 cubic metres). The critical factor during this stage is temperature. It has been found that the optimum “top of column’ temperature is around 110 Deg ...

  • Gold extraction - QueensMineDesignWiki

    The first step in gold extraction is leaching the gold which turns gold in solid form to liquid with cyanide in the presence of oxygen. Next, the gold adsorbs to the activated carbon. Finally, the carbon and gold complex is sent to elution where it is washed, and transferred to electrolysis where the gold is fully recovered. The main difference between CIP and CIL is that for CIP leaching and ...
