OPTIMIZING THE OPERATING CONDITIONS OF GOLD …
1.3.1 Elution Circuit Figure 1 shows a flow sheet of the elution circuit. The elution column operates with a 2-2.5% NaOH solution with a temperature range of 120oC-135oC. The gold is stripped from the carbon into the solution. An elution will start when there is 6 ton of loaded carbon in the measuring vessel.

Zadra elution circuit
Not process water. E/W single pass efficiency is critical for Zadra because gold not recovered is then re-circulated back to the elution column, slowing down the elution rate. Eluant flowrate is not too critical in the 2-4 BV/h range. You should be achieving optimum elution with about 30 BV of eluant through the column (15h at 2BV/h).

Activated Carbon in Gold Cyanidation
The gold cyanidation process is a primary method of gold beneficiation. Activated carbon is a critical component in the beneficiation of gold ore, allowing this widespread process to occur because of its ability to recover gold from the gold-cyanide complex. Depending on the deposit, some silver ores may also be processed via cyanidation.
