Ion Exchange Resin Recovery. In recent years, resin has begun to replace carbon as the gold recovery substrate of choice, for both resin-in-leach and resin-in-Pulp. The process used in resin recovery is similar to that of carbon, but the gold is adsorbed onto solid spherical polystyrene resin beads rather than activated carbon grains.

ACTIVATED CARBON IN GOLD RECOVERY

This article serves to discuss the fundamental aspects of gold recovery utilizing the Carbon-in-Pulp or Carbon-in-Leach processes. The purpose is to describe in simple terms what activated carbon is all about and how it adsorbs gold. The understanding of the mechanism of gold adsorption is important because the CIP/CIL processes work as

Carbon in pulp

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.

Cyanide Leaching | Mining | SGS

Activated carbon effectively removes the gold from the cyanide, as the gold is adsorbed into the pores in the carbon. This has spawned technologies such as CIP (carbon-in-pulp), CIL (carbon-in-leach) and CIC (carbon-in-columns). More recently, SGS has lead the gold processing industry with the development of resin-based technologies.
