The design of CIP/CIL/CIC is closely related the design of agitated leach circuits. The primary consideration is that the use of GAC to remove gold from leach circuit. This means carbon attrition is a major concern in the selection of equipment, activated carbon and of handling the carbon .
Carbon in leach (CIL) is an important process in gold processing involving simultaneous leaching and adsorption. The process holds the key to profitability in gold extraction. While the mechanism of leaching and adsorption are well known, the effect of different operating and design parameters on the CIL circuit performance is still empirical.

A flowsheet, showing the Carbon In Leach (CIL) process This circuit utilizes a thickener, to maintain a constant percent solids in the ore feed, necessitating less water used in the process, smaller tanks and a smaller pond. It also gives much more control over the process that a conventional CIL plant without a .
The CIL process The carboninleach (CIL) process, illustrated in Figure 3 is a variation of the CIP process. In this process carbon is added directly to the leach circuit so that the leaching and adsorption processes proceed simultaneously. Capital cost is reduced, as .
CarboninPulp (CIP) and CarboninLeach (CIL) processes have surface areas of about 1000 m²/g 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.
Apr 11, 2018· Gold Leaching( carbon in leach) process is widely used in the newly built gold leaching plants in recent years, and a lot of plants are changing into CIL as Leaching CIL 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 highgrade silver.

Carbon in Leach (CIL) process is widely used in the mining industry and in particular, it is an integral step of gold processing in gold extraction. Normally the CIL process can concentrate gold from – g/t in ore to 2000 to 6000 g/t on carbon.
Jan 04, 2017· 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 ...
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 CarboninLeach (CIL), CarboninPulp (CIP) and CarboninColumn (CIC) operations. How Activated Carbon Works
activated carbon has been the dominant process for gold extraction after leaching by cyanide in aerated alkaline slurries. The continuous processes of gold recovery by adsorption on activated carbon in agitated tanks, namely the carboninpulp (CIP) and the carboninleach (CIL) processes, have been widely used since the 1970s. Due to the economic
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.
A gravity concentrator and Intensive Leach Reactor (ILR) have been included in the design as per the FS. The CIL circuit comprises eight CIL tanks (up from six in the FS) containing carbon for gold and silver adsorption with oxygen sparged from two 25 tonne PSA Oxygen plants and a 18 tonne split Anglo (AARL) elution circuit.
The SGS carboninpulp (CIP) / carboninleach (CIL) modelling package is used to estimate the performance of a fullscale CIP or CIL plant and to derive the optimum design criteria based on the results of small scale experiments. It is a powerful design tool that uses the results

All amounts are in US dollars, unless otherwise indicated. Toronto, Ontario(Newsfile Corp. November 6, 2019) IAMGOLD Corporation (TSX: IMG) ("IAMGOLD" or the "Company") today announced positive results from a Feasibility Study ("FS") for the CarboninLeach and Heap Leach Project (the "Project") at its Essakane operation in Burkina Faso, West Africa.
The CIL (Carbon in Leach) circuit is an intermediate stage in the production of gold. The process involves dissolving the solid gold particles into solution using a process know as cyanidation. The dissolved gold in solution is adsorbed onto activated carbon. When the carbon is loaded
carbon in leach process gold processing. CIL stands for carboninleach 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 carboninpulp process
The selfcontained Carbon Scout device collects slurry samples from carboninpulp (CIP) and carboninleach (CIL) tanks to determine the distribution of the activated carbon in the pulp for each tank, to an accuracy of ± grams of carbon per litre of pulp, according to Gekko.
Carboninleach (CIL) A method of recovering gold and silver from fine ground ore by simultaneous dissolution and adsorption of the precious metals onto fine, activated carbon in an agitated tank of ore solids/solution slurry.
The methods are CarboninLeach (CIL), CarboninPulp (CIP) and Pumpcell technology. CIL and CIP are typically counter current operations while the Pumpcell technology makes use of the carousel mode of operation. The CIL mode of operation is when the leach and adsorption circuit are combined into a .
The solubilized gold is simultaneously adsorbed onto coarse granules of activated carbon directly in the pulp in the socalled CarbonInLeach process (CIL). The loaded carbon is treated at high temperature to elute the adsorbed gold into the solution once again.
Typically, the carbon in pulp (CIP) or carbon in leach (CIL) process is used for gold recovery. These processes have proven to be metallurgically efficient and mechanically robust. In order to avoid gold and carbon losses due to attrition of activated carbon, low mixing power inputs and shear rates are preferred in CIP and CIL reactors.
