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.

The remaining gold in ore is sent to cyanidation followed by carbon in pulp (CIP) gold recovery. After carbon stripping, the gold is processed through electro-winning cells prior to gold pouring. The overall gold recovery is estimated to …

The gold cyanidation process is a primary method of gold beneficiation. 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.

On cyanide leaching of gold in the tank system, activated carbon is very important to use when in the process of recovery of dissolved gold, either by introducing direct to the Carbon In Leach (CIL) in tank or to the Carbon In Pulp (CIP…

required for gold leaching by cyanidation. Another example of chemical interference is the presence of graphitic carbon in a gold ore. This species, which occurs naturally in many orebodies, particularly in the SW United States and West Africa, is able to re-adsorb gold cyanide from the leach solution, lowering overall gold recovery.

Cyanide leaching is the standard method used for recovering most of the gold throughout the world today. The process originated around 1890 and quickly replaced all competing technologies. The reason was strictly economical in nature. Where amalgamation plants could recover about 60% of the gold present, cyanide could recover about 90%.

At the Misima gold mine (Papua New Guinea), the ore grade was 1.5 g/t gold and 9.0 g/t silver which necessitated the use of six by ten tonne carbon stripping columns. Initially, Misima Mines produced a mixed gold, high silver, dore …

Cyanidation leaching is the primary means of recovery of fine gold and silver. In this process, solutions of sodium or potassium cyanide are brought into contact with an ore which may or may not have required extensive preparation prior to leaching. Gold and silver are dissolved by cyanide in solutions of high pH in the presence of oxygen.

Jun 13, 2014· The APT Tritank is a step away from the conventional and a breakthrough in the cyanidation method of gold recovery. The distinguishing feature of this plant is its triangular design, which was adopted as opposed to the out-dated circular design due to the proven enhancement in mixing and greater gold dissolution rates.

The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carbon-in-leach. This is a gold extraction process called cyanidation where carbon is added to the leach tanks (or reaction vessel) so that leaching and adsorption take place in the same tanks.
