Gold Extraction an overview ScienceDirect Topics

The gold extraction gap between the two systems increased with time. Plant data indicated that the addition of lead nitrate increased gold extraction from 87% to 91.7% and, for the 18 months evaluated, resulted in gold production in excess of 49,000 oz higher than that estimated for the nonlead nitrate reagent scheme.

Elution and Carbon Reactivation Resource book

During the CIL process, gold is leached from the ore using an alkaline cyanide solution. The resulting gold cyanide complex ions are then concentrated and separated from the slurry by adsorbing onto activated carbon. Elution is the next step in the process, whereby the adsorption of the gold cyanide complex onto carbon is reversed.
