Activated carbon reduces fines formation and increases yield. A major use of activated carbon in mining is in gold recovery, where granular activated carbon (GAC) is used for adsorption of the gold-cyanide complex in carbon-in-pulp (CIP) and carbon-in-leach (CIL) systems, or in carbon-in-column (CIC) systems after a heap leach operation carbon.
There are several gold processing operations requiring activated carbons: CIP (Carbon in Pulp): gold pulp is mixed with sodium cyanide, then is contacted with activated carbon in a series of large agitated adsorption tanks CIL (Carbon in Leach): similar to CIP but leaching and adsorption occur simultaneously
In each, activated carbon is used to extract gold from the cyanide leach solution. Such a carbon recovery system offers high recovery rates and lower capital and operating costs. These carbon recovery techniques include: Carbon-in-pulp. The ore is crushed, finely ground and mixed with the cyanide leach solution to form a slurry in an agitation ...

Nov 05, 2018· Gold-Bearing Carbon Because the gold-bearing carbon is much larger than the rest of the pulp matter, it can be easily parsed out by screening the substance through a wire mesh. Once carbon particles are separated, the pulp is "eluted," or bathed in a solvent to wash away the non-gold-bearing, and therefore now unnecessary, matter.
Carbon-in-pulp The ore is crushed, finely ground and mixed with the cyanide leach solution to form a slurry in an agitation tank. The activated carbon is introduced into the slurry and then removed by screening once it is fully loaded or "pregnant" with gold. Carbon-in-leach This process is very similar to the CIP process.
Metallurgical ContentLearn CyanidationDevelopments in the Carbon-In-Pulp ProcessDesign Criteria Commercial Operations Cyanide is a lixiviant, or reagent that is used to leach, often in tanks, gold from a solid matrix and form a gold cyanide complex. 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 ...
In the gold industry, there are three main methods for extraction of the metal, all of which use granular activated carbons in the recovery of gold from cyanide leachate solutions: – Carbon-in-Pulp (CIP) – Carbon-in-Leach (CIL), includes 'Heap Leach' – Carbon-in-Column (CIC) Related Applications – Gold .
Gold ore . Prominer maintains a team of senior gold processing engineers with expertise and global experience. These gold professionals are specifically in gold processing through various beneficiation technologies, for gold ore of different characteristics, such as flotation, cyanide leaching, gravity separation, etc., to achieve the processing plant of optimal and cost-efficient process designs.
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
CIP ( Carbon In Pulp) process is suitable for the treatment of oxidized gold ore with low sulfur content and mud content.It is unsuitable for the gold ore with high-grade silver as well. Generally, the proportion of gold and silver should not exceed 1:5. The best conditions for Carbon In Pulp process in China: PH=10-12, sodium cyanide concentration is not less than 0.015%, the particle size of ...
Today's gold mining operations optimize efficiency and output through the use of superior Haycarb gold recovery carbon technology. Our high density carbons with particle to particle consistency in activity and shape is an ideal solution for applications in CIL (carbon-in-leach), CIP (Carbon-in-pulp) and CIC (carbon-in-column) processes.
Activated carbon in touch with a pulp comprising gold may normally recover over 99.5 percent of the gold at the solution in 8 to 24 hours, based on the reactivity of the carbon, the quantity of carbon used along with the mixer's efficacy. The carbon is subsequently separated from the pulp by wateror displays which are swept hydrodynamically ...

The coconut shell activated carbon we provide is made of imported high quality coconut shell. It is mechanically fired, has good adsorption and wear resistance, high strength and ...
In the gold industry, the use of activated carbon to separate gold from cyanide leaching solutions has become an industry standard for efficient gold recovery in Carbon-in-Leach (CIL), Carbon-in-Pulp (CIP) and Carbon-in-Column (CIC) operations.
Gold CIP Production Line. Process Introduction. CIP (Carbon in pulp) process is a high efficient method to leaching and recovering gold from gold ore, The most different from CIL process is in CIP process, gold leaching and adsorption are separated, first leaching, and then adsorption.
The carbon in the reactor into which pregnant pulp is fed (referred to as the first reactor) becomes highly loaded with gold. Loaded carbon values on operating plants range from 300 to 20 000 grams of gold per ton of carbon, a concen-trating factor of about 1 000–1 500. A portion of the loaded carbon is periodically removed from the first ...
Sslurry at a rate of approximately 3.785 cu. m. per minute (1,000 GPM) is placed in contact with activated carbon. A simplified flow-sheet of the CIP Plant is shown in Figure 2. For years it has been known of the affinity of activated carbon to adsorb preferentially the gold and silver in cyanide complex form. This operation takes place in five circular tanks that provide a total pulp ...
Carbon in Leach, Carbon in Pulp, Silver Recovery Equipment manufacturer / supplier in China, offering Gold Lixiviation Agitation Tank for Gold CIL Plant, Forced Air Type Gold Flotation Cell of Beneficiation Recovery Machine, Forced Air Type Gold Flotation Cell of Beneficiation Recovery Equipment and so on.
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. CIP process is suitable for the treatment of oxidized gold ore with low sulfur content and mud content.
There are predominantly three methods employed in industry to adsorb leach gold from a pulp stream onto activated carbon. The methods are Carbon-in-Leach (CIL), Carbon-in-Pulp (CIP) and Pumpcell technology. CIL and CIP are typically counter current operations while the Pumpcell technology makes use of the carousel mode of operation.
