One of the main bottlenecks in the carboninpulp process for the recovery of gold is the elution procedure, which typically requires the heating of caustic cyanide eluants to high temperatures for 16 to 24 hours. The present work demonstrates that sodium sulphide solution as an alternative eluant can effect complete elution in about 4 hours at ambient temperatures.

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 appliions where the presence of competing silver or copper does not prohibit its use.
