Calgon Carbon's high-quality GACs are proven to maximize recovery efficiencies by reducing gold loss and minimizing carbon consumption when used for Carbon-in-Leach (CIL), Carbon-in-Pulp (CIP) and Carbon-in-Column (CIC) gold extraction techniques.
Coconut shell activated carbon (6X12, 8X16 mesh) is suitable for gold rocovery in modern gold mines, mainly used for heap separation or charcoal pulp extraction of precious metals in the gold metallurgical industry. The coconut shell activated carbon we provide is made of imported high quality coconut shell.
Activated carbon is widely used for gold recovery from cyanide leach liquors via in-leach carbon-(CIL) or carbonin-pulp (CIP) technology. From all the base metals cyanide complexes typically - present together with gold in the leach liquor, only copper, and to a lesser extent nickel, are loaded onto activated carbon.
Activated carbon adsorbs dissolved gold from gold leach pulp complicated to be absorbed through the pores of this carbon.The most cost-effective procedure would be to make adsorption of the excavated gold on activated carbon, causing an easier solid-solid separation based on size.
Gold Recovery CPL Activated Carbons has extensive operational and commercial experience in the supply of specialised grades of activated carbons into the precious metal recovery industry. Activated carbons are used to recover gold from cyanide solutions, which are percolated through gold .

This article serves to discuss the fundamental aspects of gold recovery utilizing the 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
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. How Activated Carbon Works
1. Introduction. The carbon in pulp process for gold recovery involves treatment with cyanide under aerobic conditions at high pH, to give the Au(CN) 2 − ion, which is then recovered by adsorption on carbon, followed by elution of the Au(CN) 2 − in caustic solution and electrowinning of the gold. In this study, the stability of models of the carbon–gold complexes are studied by Hartree ...
Jul 21, 2016· This invention relates to the recovery of gold from carbon fines. Carbon fines are produced when carbon, which is used in a carbon-in-leach (CIL) or carbon-in-pulp (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.

Gold Recovery. Activated Carbon fulfills a crucial role as the key element in Leach Circuits, Carbon in Leach, and Carbon in Pulp processes. We are a major manufacturer of activated carbon specialized for the gold mining industry and precious metals recovery to be utilized in both Carbon Leach and Carbon Pulp .
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.
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.
In the recovery of noble metals, including gold, silver and members of the platinum group, the ores or tailings are subjected to the action of various leaching agents, namely, sodium cyanide, thiourea, chlorine and aqua regia and optionally a leaching aid, such as chloride ions. The resulting slurry is then diluted to an optimum pulp density of 0.1 to 10.0% and allowed to stand in a holding ...
By replacing the Merrill–Crowe zinc cementation step, carbon-in-pulp (CIP) and carbon-in-leach (CIL) recovery provided a process that allowed the treatment of lower grade and problematic ores (e.g., high-clay ores), at lower capital and operating costs and higher metal recoveries.
We produces wide range of granular coconut shell activated carbons for gold recovery applications. Activated carbon use for gold recovery has been increasing significantly in the last 30 years as the improving control, quality, and quantity of the activated carbon being produced .
Activated carbon in gold recovery. Even to produce few grams of gold, thousands of tons of ore must be mined, crushed, roasted, ground, treated, pulped and leached. Activated carbon plays a key role in capturing the gold from its ore. In any gold mine, any gold that is not adsorbed by activated carbon .
Someone else suggested flotation recovery but that is not relevant to your question. Without experience I can only guess that flotation could be used, and guestimate that the cost is not worth the recovery or it would be used already. Gold in carbon carries significant costs at a refinery, do you have any numbers in these questions?
Carbon adsorption is increasing using in newer plants for gold recovery. Carbon in Pulp (CIP) technique involves contacting the leached pulp with granular carbon in a series of agitating tanks with a sufficient retention time. Selected summary of patented gold recovery processes and examples of commercial mining and
The carbon in pulp method is only used where tank leaching is utilized for the recovery of gold from the ores and this is not the case in most large gold mines today, since heap leaching is the lowest cost method for recovering gold from ores containing from a few grams to 5 or 6 grams per ton.
Particularly in gold recovery, activated carbon is the key element in CIC, CIL and CIP processes. As a major manufacturer of activated carbon specialized for the gold mining industry and precious metals recovery, we service some of the world's largest mining companies.
carbon is most often used to adsorb gold from dilute alkaline cyanide solutions. The gold is dissolved as the Au(CN) 2-complex and is recovered from the solution by Carbon-in-Pulp (CIP) or Carbon-in-Leach (CIL) processes. Activated carbon loaded with gold must be treated by an elution step to desorb the gold for subsequent recovery.
and strip the carbon of gold. Gold is then removed from the solution by electrowinning. Stripped carbon is returned to adsorption for reuse. The major advantage of carbon-in-pulp recovery over Merrill Crowe recovery is the elimination of the leached ore solids and liquid separation unit operation.
