Mar 31, 2016 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.
Elution (Gold desorption) and Electrowining Carbon stripping in small mining scale is combined together with electro wining. The stripping column is divided into two parts, the bottom one is elution column and the top part is electro wining cell.

Jun 20, 2019 It was not, however, until methods for chemically desorbing gold from loaded carbon were developed, that the process came into widespread use for gold recovery from ore. The Micron elution procedure takes advantage of the enhanced stripping rate achieved with alcohol, but confines the alcohol to the closed stripping unit.

Numerous articles have appeared on the mechanism of the adsorption of gold cyanide onto activated carbon. In contrast, little information is available on the mechanism of elution of the adsorbed gold. It is the objective of this article to formulate such a mechanism on the basis of batch and column elution tests without analyzing adsorbed species on the carbon directly.
Process overview and description The CIP process A block-flow diagram of a typical CIP plant for a non-refractory gold ore is shown in Figure 2. Table I and Table II illustrate the capital and operating cost breakdowns for a typical South African gold plant. These figures are not a standard but reflect the nature of the ore and
