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.

The temperature is further raised by a steam heat exchanger.

Carbon in pulp Wikipedia

Carbon in pulp (CIP) is an extraction technique for recovery of gold which has been liberated into a cyanide solution as part of the gold cyanidation process.. Introduced in the early 1980s, Carbon in Pulp is regarded as a simple and cheap process. As such it is used in most industrial applications where the presence of competing silver or copper does not prohibit its use.
