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. CIP conducts the leaching and recovery ...
Outotec has released a fully automated in-situ measurement system that, it says, can minimise gold solution losses in carbon-in-pulp (CIP) and carbon-in-leach (CIL) circuits. Outotec CarbonSense is a system that is directly immersed in the slurry, eliminating the need for sample transfer and ensuring optimal carbon management, according to the ...
Their process flows basically include the following steps: (1) using activated carbon to absorb and extract gold from cyanide pulp or solution to produce gold loaded carbon; (2) desorbing the gold ...
Carbon in pulp（CIP）is one of the methods of gold extraction by cyanidation.It is the process of gold cyanide for carbon adsorption after the cyanide leaching of gold-containing materials is completed. In actual production, most CIP plants will encounter various problems, which not only affect the normal operation of gold beneficiation, also seriously damage the economic benefits of CIP plants.
The gold carbon in pulp (CIP) Processing refers to the process of grinding all the gold ore into a slurry (-200 mesh content accounts for more than 90-95%). Cyanide leaching was carried out first, then activated carbon was used to absorb the Gold loaded carbon from the pulp, purification and smelting of the gold-loaded Gold in the medium ...
Dec 10, 2019· CIP and CIL method is a new process for processing precious metal-containing pulp on the basis of the conventional cyanide gold extraction method.In CIP process, leaching and adsorption are two operations, the leaching tank is used for cyanide leaching of the slurry, and the carbon slurry tank is used for adsorption of gold by activated carbon.
Presented at the Alta 2014 Gold Conference, 24–31 May 2014, Perth, Australia. ... Activated carbon is widely used for gold recovery from cyanide leach liquors via carbon-in-leach (CIL) or carbon-in-pulp (CIP) technology. From all the base metals cyanide complexes typically ... These include Avocet Mining's Penjom Gold Mine in Malaysia and ...
The SGS CIP/CIL modelling package maximizes gold extraction efficiency by reducing soluble gold losses from a CIP or CIL plant. We can help you accomplish this by: • Increasing the number of adsorption stages. • Increasing the amount of carbon in each stage. • Reducing gold loading by moving carbon to elution and regeneration more rapidly.
Activated carbon for mining industry is commonly utilized in the absorption of golden cyanide complexes in gold processing.This procedure can be put on the crystal clear answer via a fluidized bed column or take part in the process of leaching on the tank along with also the separation of carbon.
A process for adsorbing gold from a leach pulp by means of activated carbon is described in which the leach pulp (the leach solution together with the subdivided gold bearing ore) is diluted to a specific gravity of less than that of the activated carbon and is subsequently passed upwardly through a multistage liquid/solid contacting column.

Gold Recovery from Solution The common processes for recovery of the solubilized gold from solution are (certain processes may be precluded from use by technical factors) [5,6]: Carbon Adsorption Merrill-Crowe process Electrowinning Ion-exchange/Solvent Extraction (i) Carbon Adsorption The process known as carbon in pulp, or charcoal in pulp or ...
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 materials, agitation leaching and countercurrent carbon adsorption, gold-loaded carbon ...

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.
Gold CIP process eliminates the slurry washing and solid-liquid separation operations, directly uses granular activated carbon to absorb gold from pulp, and optimizes the traditional cyanidation gold extraction process, which simplifies the industrial production process, improves the leaching efficiency and reduces the production cost.

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.
To Attain this ore particles should normally be Smaller than 100 μm whereas the carbon particles must be bigger than 500 μm. Adsorption is reached by Contacting the carbon using the pulp that is infected. This may be achieved while the gold is still being siphoned together with all the CIL-process, or after leaching with all the CIP-process.
With wide range of applications, it can be setup for Carbon-In-Pulp (CIP), Carbon-In-Leach (CIL), or Carousel operation. The Tritank is not a cyanidation tank, it is a cyanidation system. With six reaction compartments or sectors condensed into one conventional tank, not only is the footprint smaller, but a whole host of advantages accrue to ...
Using CIP, the minute (but economically important) quantity of gold that remained in the barren solutions and solid residues from conventional processing can be recovered. In the CIP process, activated carbon is used to adsorb the gold directly from the cyanided pulp in a series of large adsorption tanks.
The main difference between CIL and CIP lies in the extent to which gold is leached prior to carbon adsorption. In CIL operations, carbon is added to the leaching tanks, therefore the leaching reaction and adsorption occur simultaneously. During the CIP process, most of the leachable gold has been leached prior to the first adsorption stage.
The dissolution of gold through cyanidation, either Carbon in Pulp (CIP) or Carbon in Leach (CIL), is an oxidizing reaction. Generally added oxygen, in the form of dissolved oxygen in solution, improves the process as the rate of gold dissolution is directly proportional to the amount of dissolved oxygen in solution. Typically oxygen may be ...
> The selection of Carbon-in-Pulp or Merrill-Crowe is based on economical considerations > As the throughput and precious metal values increase, the inventory of carbon needs to be higher ― Plant must be expanded to process more activated carbon. ― Gold hold up in process > At some point it will be less economical to operate a CIP process
