ACTIVATED CARBON IN GOLD RECOVERY - Kemix

2018-1-15  Carbon-in-Pulp (CIP) and Carbon-in-Leach (CIL) processes have surface areas of about 1000 m²/g i.e. one gram of activated carbon (the amount of which will occupy the same space as the end of a person's thumb) has the same surface area as two football fields. The high surface area is contained in the millions of pores of varying sizes, these being

Carbon-In-Pulp - Jacobi Group

2021-11-8  With carbon-in-pulp, the ore is finely ground and the gold is solubilised using a cyanide leach in a series of tanks. The granular activated carbon is added to the leached slurry, where the carbon adsorbs the gold from the slurry solution and is then removed from the slurry by coarse screening.

1991-8-1  Attrition of activated carbon in either the carbon-in-pulp (CIP) or carbon-in-leach (CIL) method of gold extraction can lead to, at the least, loss of expensive carbon that has to be made up, and at the worst, loss of both the carbon and any gold that was attached to it. Carbon attrition therefore represents a significant factor in both the efficiency and cost of the extraction process, and ...

Activated Carbon in Gold Cyanidation

Activated carbon is a critical component in the beneficiation of gold ore, allowing this widespread process to occur because of its ability to recover gold from the gold-cyanide complex. Depending on the deposit, some silver ores may also be processed via cyanidation. Here too, activated carbon is the catalyst for recovery of this precious metal.
