adsorbing onto activated carbon. 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).

Not process water. E/W single pass efficiency is critical for Zadra because gold not recovered is then recirculated back to the elution column, slowing down the elution rate. Eluant flowrate is not too critical in the 24 BV/h range. You should be achieving optimum elution with about 30 BV of eluant through the column (15h at 2BV/h).
