Modeling of the carbon in pulp (CIP) process in gold cyanide leaching plants… 843 Fig. 1. Carbon adsorption unit of a carbon in pulp (CIP) Gold Ore Cyanide Leaching Plant

The CIL plant is fully equipped with crushing and grinding circuits, small gravity circuit for coarse gold, gold absorption and desorption leach circuits, electrowinning and gold pouring facilities. The plant has operated efficiently, recovering around 97% of the gold from the ore.

Carbon-in-pulp (CIP) is the sequential leach then absorption of gold from ore. During the CIP stage, pulp flows through several agitated tanks where sodium cyanide and oxygen have been added to dissolve gold into solution.

Carbon adsorption, or "collection on carbon," is an extraction technique that mixesThe grade and type of ore determine the processing method used.Heap leaching is used when the ore contains a lower grade of mineral content.the gold is extracted using a process known as carbon stripping or …

The activated carbon is added in leach, with gold adsorption occurring nearly simultaneously with gold dissolution by the cyanide solution. CIL is often employed when native carbon is present in the gold ore and adsorbs the leached gold, preventing its recovery.

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.

Carbon In Pulp is the absorption of compounds into carbon Dicyano Aurrat. In the process extracting gold by carbon in pulp with activated carbon occurs after the leaching of mineral ore slurry in a tank.

President Brand, in effect, recovered an extra 0.15 gm gold per mt of ore (0.0044 oz/T), assuming 50% slolids slurry, by switching to high gold adsorption rate carbon. To put carbon costs in perspective, it is useful to consider the amount of additional gold it is necessary to recover to offset the cost of using high activity carbon.
