CIP AND CIL CIRCUIT MODELLING The SGS carbon-in-pulp (CIP) / carbon-in-leach (CIL) modelling package is used to estimate the performance of a full-scale CIP or CIL plant and to derive the optimum design criteria based on the results of small scale experiments. It …
The CIL and CIP are slow processes, and in order to improve gold extraction and recovery, they occur continuously in a cascade of large agitated tanks. Figure 1 schematically shows the CIL or CIP circuit with three reactors. Note that the pulp flows by gravity from one tank to the next by overflow, the
CIP and CIL Carbon-in-pulp (CIP) 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.
Haycarb has been a pioneering supplier of activated carbon for Carbon in Pulp (CIP), Carbon-in leach (CIL) and Carbon-in-circuit (CIC) processes in gold mining since the 1970s.
CIL is often employed when native carbon is present in the gold ore and adsorbs the leached gold, preventing its recovery. The activated carbon used in the CIL circuit preferentially adsorbs the gold over the native carbon, and thus allows the gold to eventually be recovered for stripping.
INSIGHTS FROM SIMULATION OF A CIL/CIP CIRCUIT. These equations were programmed in Excel, solution outputs from one tank being the input to the next and the carbon output from one tank being the carbon input to the preceding tank. The number and function (leach only or leach and adsorption) of the tanks is set in any ...
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 conditions of CIP and CIL circuits are such that hardness and gold adsorbality are equally important, i.e. a good activated carbon for gold recovery is a compromise equally important, i.e. a good activated carbon for gold recovery is a compromise
LEACHING & ADSORPTION Resource Book. RESOURCE BOOK ... The CIL circuit consists of two separate trains of tanks, with seven tanks in each train. In conventional CIL circuits, leaching takes place in the presence of carbon and therefore leaching and adsorption occur simultaneously. The CIL circuit at SDGM can be considered a
PDF | On Jun 10, 2010, Alex Mezei and others published Factors influencing the rate of gold cyanide leaching and adsorption on activated carbon, and their impact on the design of CIL and CIP circuits
AusIMM - Metallurgical Plant Design and Operating Strategies, Perth, September 2004 _____ _____ _____ leach circuit only rather than the traditional full ore leach circuit such as CIP/CIL. The circuit incorporates crushing and coarse grinding to 200µm, then gravity recovery, possibly in combination with flotation followed by intensive ...

In the 1980s the carbon-in-leach (CIL) circuit configuration became the process design of choice due mainly to its lower capital costs. With 40 years of operational experience, CIP/CIL for gold recovery is now mature a technology, whose operations and limitations are well understood.
CIL circuits are similar to CIP circuits with the exception that leaching and extraction occur simultaneously in agitated leach tanks that also contain carbon and are equipped with carbon retention screens. The evaluation of agitated tank leaching verses CIP and CIL circuits is not as complex as the heap leach-agitated tank leach analysis.
CIP AND CIL CIRCUIT MODELLING. fullscale CIP or CIL plant and to derive the optimumCIP/CIL modelling package allows for optimization and creates better plant designs.Example:CIL plant in Northern Ontario,Canada that treats low grade gold ore flotation tailing. Chat en línea.
This process is very similar to the CIP process. The main differences lie in the preparation of the slurry and method for removing the gold from the leachate. In a CIL process, the carbon is mixed with the leachate solution, not with pulp. This is a much less abrasive system meaning that the carbon lasts much longer than in a CIP process.
pulp in an environment appropriate for leaching in the CIP reactors. This additional leaching provides additional economic benefit. The CIL process The carbon-in-leach (CIL) process, illustrated in Figure 3 is a variation of the CIP process. In this process carbon is added directly to the leach circuit …
with the Merrill Crowe Process, CIP or CIL the use and further development of gravity concentration devices for the recovery of gold in modern gold plants went into decline. Limitations of the CIP/CIL process recently saw the re-emergence of gravity concentrators either in the grinding circuit or in treating the CIP/CIL tailings in many operations.

Jan 01, 2018· The objective of the test program (completed by SGS Canada in 2013) was to investigate and model the combined flotation concentrate / tailing carbon-in-leach (CIL) circuit and suggest ways to improve gold recovery. The metallurgical test program included mineralogy, rheology, and carbon modelling testwork.
Gold recovery increase in CIL circuit. Various trials have shown the potential of PIONERA BioPolymer to increase metal recovery in leaching circuits. This is especially relevant in the CIL/CIP circuits used in gold processing. The benefit of PIONERA BioPolymer is also observed in the Merrill Crowe process.

The nature and chemistry of an ore deposit determine the processing method used in gold production. There are many processing techniques for gold ore. The most common is cyanidation in carbon-in-leach (CIL), carbon-in-pulp (CIP) or carbon-in-column (CIC) circuits. has a wide range of valves ideal for CIL, CIP, and CIC processing.
The SGS carbon-in-pulp (CIP) / carbon-in-leach (CIL) model is used to evaluate the performance of operating CIP and CIL circuits and/or to derive the optimum design criteria for greenfield projects. Samples (pulp and carbon) are tested in a series of small-scale batch experiments to determine rates of gold leaching and adsorption on carbon from various […]
