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 applications where the presence of competing silver or copper does not prohibit its use.
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 Mass balance can be defined by Eqs (3) and (4), Vs(Cn 1 Cn) Vc(Q n 1 Q n) (3) tc Mc Vc . (4) The parameters could be described as, Vs – solution flow rate in slurry Mg/hour;
Cyanidation carbon adsorption process is the most widely used in gold cyanide extraction process . The principle in brief is the carbon could adsorb liquid gold from cyanide solution . In 1970s, with the research and establishment of adsorption of carbon loaded with gold and the recovery of carbon discharge gold, make recycle the carbon and reduce the cost, and easy to process the gold ...
process is reversed and the gold is stripped off the carbon back into solution, electrowon and smelted into bars. The remaining ''barren'' slurry reports to the tails thickener and is pumped to the tails dam. The CIL circuit consists of two separate trains of tanks, with seven tanks in each train. In
The slurry outlet on the screen matches the face on the tank launder, to which it hooks and forms a tight seal without the need for fasteners or clamping devices. The carbon retention screen can be removed from its tank and a clean one installed in its place in five to ten minutes.
Activated carbon is then used to separate and store the gold, which is removed as the final step of the process. There are three basic operating systems in use for modern gold recovery: Carbon in Pulp: Carbon in pulp, or CIP, processing occurs when the leaching takes place in an agitation tank before the activated carbon is introduced.
The absorptive properties of activated carbon are due to the microporous structure of each grain resulting into large surface area per unit column of carbon. In the gold industry, activated carbon is utilized in CIP/ CIL process to transfer dissolved gold from cyanide leached slurry to elution column where gold is desorbed from the carbon.

The best conditions for CIP process in China: PH=1012, sodium cyanide concentration is not less than %, the particle size of activated carbon is, the best choice of carbon is coconut shell activated carbon, and the slurry concentration is 4045%. CIP P lant C onsists of F ollowing S teps: 1. Crushing and S creening
cyanidation process, granular activated carbon is added to the leached slurry. The carbon adsorbs the gold from the slurry solution and is removed from the slurry by coarse screening. In practice, this is accomplished by a series of five or six agitated tanks where carbon and ore slurry are contacted in a staged countercurrent manner.
In the absorption stage, this solution flows through several agitated tanks containing activated carbon. Gold absorbs on to the activated carbon, which flows countercurrent to the pulp, while screens separate the barren pulp from the goldloaded carbon. Carboninleach (CIL) is a simultaneous leach and absorption process.
How the Carbon Scout works. The process used by the Carbon Scout to determine the distribution of activated carbon produces results in line with manual carbon concentration measurements conducted by plant operators. The process involves: > Collecting a sample from the tank > Screening the sample (to separate the pulp and activated carbon particles)

The remaining slurry consisting of fiber, starch, and protein is finely ground and screened to separate the fiber from the starch and protein. The starch is separated from the remaining slurry in hydrocyclones. The starch then can be converted to syrup or it can be made into several other products through a fermentation process. Inspection ...
place in CIP plants, due to the additional residence time of pulp in an environment appropriate for leaching in the CIP reactors. This additional leaching provides additional economic benefit. The CIL process The carboninleach (CIL) process, illustrated in Figure 3 is a variation of the CIP process. In this process carbon is added

Gold CIL (Carbon in Leach) Process is an efficient design of extracting and recovering gold from its ore. By cyaniding and carbon leaching crushed gold ore slurry simultaneously, CIL process lower the gold mining operation cost and increase gold recovery rate to a degree of 97%.
Jul 21, 2016· Carbon fines are produced when carbon, which is used in a carboninleach (CIL) or carboninpulp (CIP) process for the recovery of gold, is broken. Typically, these fines, loaded to some extent with gold, exit from a last adsorption stage of the process and are then lost.
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 process mainly includes the following steps: the preparation of leaching materials, agitation leaching and countercurrent carbon adsorption, goldloaded carbon ...
The CIP and 28cp profiles use high release angles to minimise blinding by carbon. The CIP profile provides excellent open areas. The 28cp profile has additional strength needed for AAC MPS and AAC Pump Cell cylinders where increased flow and slurry turbulence generate higher forces.
