  • 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.

    Aug 15, 20190183;32;Gold cyanidation, also called cyanide leaching, is a process used to extract gold from raw ore taken from the ground. It uses cyanide to dissolve the gold within the rock, which, itself, is not soluble in cyanide. The gold is then drawn out in a liquid form that can be treated to remove the cyanide.
