2.2 Tank Operations (Carbon-in-Pulp and Carbon-in-Leach) In Carbon-in-Pulp and Carbon-in-Leach cyanidation methods, primary leaching takes place in a series of tanks. Finely ground gold ore is slurried with the leaching solution. The resulting gold-cyanide complex is then adsorbed on activated carbon.
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 a result of the gold adsorption mechanism, which is a chemical occurrence. Factors that
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.
The cyanidation gold extraction process is the main method for extracting gold from ores or concentrates, which is mainly divided into two processes, namely, tank leaching cyanidation method and heap leaching cyanidation method. The heap leaching method is mainly used to .
Carbon in pulp process. Gold Carbon-in-pulp (CIP) production 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.

is cyanidation for carbon-in-leach (CIL), carbon-in-pulp (CIP) or carbon-in-column (CIC) circuits. The gold leaching process starts with comminution. The run-of-mine ore is crushed and ground to a fine particle size. Water is added to the process to create a mud-like slurry. The slurry is then pumped
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. CIL is slightly different from another gold extraction process called CIP or carbon-in-pulp process.
The Production Line of All Sliming Cyanidation CIP Process. All sliming cyanidation CIP method to gold smelting process refers to all the gold ore grinding pulverized pulp (-200 mesh content of 90 ~ 95%), the first cyanide leaching, and then use activated carbon .
The carbon in pulp (CIP) and carbon in leach (CIL) processes became firmly established in the gold mining industry in the 1980s, initially in South Africa and Australia, from where they spread rapidly to all the gold producing regions of the world. The percentage of annual global gold production by activated carbon-based processes grew from ...

3. Carbon-In-Leach (CIL): The carbon-in-leach process integrates leaching and carbon-in-pulp into a single unit process operation. Leach tanks are fitted with carbon retention screens and the CIP tanks are eliminated. Carbon is added in leach so that the gold is adsorbed onto carbon almost as soon as it is dissolved by the cyanide solution.
leach solutions are frequently high in solids due to fine particle washing from heaps. Down flow carbon columns are rarely used for gold recovery, because they act like sand filters and are subsequently subject to frequent plugging. 2. Carbon-In-Pulp (CIP): Carbon-in-pulp operation is a variation of the conventional cyanidation process.
2. Cyanidation carbon in pulp process. Carbon pulp extraction process (CIP method and CIL method) is to put activated carbon into the cyanidation pulp, and the dissolved gold is adsorbed on the activated carbon, then the gold is extracted from the activated carbon. This process mainly includes the following steps: the preparation of leaching ...
Gold cyanidation (also known as the cyanide process or the MacArthur-Forrest process) is a hydrometallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complex. It is the most commonly used leaching process for gold extraction.
The carbon in pulp method can also be called all-sliming cyanidation. It is a method in which activated carbon is put into cyanidation pulp to adsorb the dissolved gold onto the activated carbon, and then the gold is extracted from the activated carbon. The carbon in leaching method is developed on the basis of the carbon in pulp method. On the ...
Dec 20, 2018· The gold ore cyanide leaching pulp contains a certain amount of Fe2+, Cu2+, Zn2+, S2-, Fe3+ plasma, in addition to the metal sulfide mineral pyrite, pyrrhotite, chalcopyrite and sphalerite. The leaching process consumes a large amount of cyanide and dissolved oxygen, and reduces the cyanide leaching .
The process design of gold leaching and carbon-in-pulp circuits contaminants. These are removed by thermal regeneration of the eluted carbon, typically in a rotary kiln at temperatures of 650–750°C. Regeneration is carried out in a steam atmosphere to minimize carbon degradation due to oxidation. The eluted and regenerated carbon is screened ...
