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
gold from the slurry The applied technology varies from plant to plant, with CIL being the most widely used processing method In a CIL leaching circuit, a cyanide solution and oxygen are added to the slurry in large steel leach tanks The gold dissolves from the ore into the solution The activated carbon is fed
circuit In a CIL plant, the carbon granules are added directly into the gold leaching tanks, so that leaching of gold (from the ore phase to the leachate), and adsorption of gold (from the leachate to the carbon), occur simultaneously In a CIP plant, a series of small adsorption tanks is installed after the leach plant
the mechanism of gold adsorption is important because the CIP/CIL processes work as a result of the gold adsorption mechanism, which is a chemical occurrence Factors that affect the adsorption of gold are discussed Finally, performance monitoring methods that help control the operation of the CIP/CIL process are discussed 2
Gold dissolution in this section of the plant is weak because the gold content of the ore is low; in addition, there are uncertainties on the measurements, especially for the first two tanks However, for proposes of illustration it is taken into account in the simulations presented in this study
The occlusion of gold by other minerals and the fine grain size of gold associated with them can be factors limiting the gold recovery from the CIL circuit post copper flotation in copper–gold plants Regrinding the CIL feed raises the CIL stage gold recovery by exposing more gold surfaces to cyanide
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
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 Gold leaching plants use valves for numerous flow control and isolation servic

This paper is concerned with the estimation of the gold inventory in the carbon in leach (CIL) tanks of a gold processing plant in Quebec, Canada For that particular plant the CIL tanks may contain the gold that fed the circuit during 9 days
pulp leaves the last tank in the adsorption cascade the concentration of gold in the aqueous phase is typically between 0001 and 002 ppm with a value of 001–0005 ppm regarded as a practically achievable value for most well-designed and operated plants This represents a gold recovery of 90–99% depending on the tenor of the feed solution
A wide variety of cil gold plant options are available to you, There are 869 cil gold plant suppliers, mainly located in Asia The top supplying country is China (Mainland), which supply of cil gold plant respectively Cil gold plant products are most popular in ,
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

Gold recovery increase in CIL circuit , A plant scale trial at a gold mine in Canada showed a recovery increase in gold of about 1% over a range of different feed head grad Figure: Gold recovery in a 11 day long plant scale trial in CIL circuit With the addition of 600 g/t of PIONERA L-800, slurry solids can increase from 45% to 525% .
Gold Carbon In Leach Plants Updated January 2017 Gold Processing Plant, Carbon In Leach CIL Plant From the ball and/or autogenous mill, slurry is pumped to the CIL leach tanks where lime adjusts the pH, if necessary, and it is agitated for the desired period of time Air is added to increase the reaction rate and shorten the leach time more+
2017 Hot sale CIL plant equipment leaching tank to extract gold— Product description Leaching Tank is applicable to carbon process and rubber chemical process Its upper and lower layer of impellers are of steel plate encapsulated with rubber,which are connected by means of bolts
This 3500 TPD CIL plant was put on care and maintenance in 2018 and is now for sale and offered by Savona Equipment Ltd The process plant which has a design capacity of 13 Million TPA, comprises of a crushing circuit, a ball and SAG mill grinding circuit while precious metal recovery is through a carbon in leach process and electrowinning
Leaching of gold using cyanide is the most common chemical extraction method, but it was definitely not done in the safest and most efficient way until now APT triangular cyanidation tanks use up far less material and land footprint, whilst optimizing all the necessiti
This plant processes 4 million tons of ore per year with an average gold content of 0043 ounces of gold per ton of ore Approximately 85% of the gold is recovered in the plant From the ball and/or autogenous mill, slurry is pumped to the CIL leach tanks where lime adjusts the pH, if necessary, and it is agitated for the desired period of time
SMALL SCALE CIP/CIL CYANIDATION PLANT Home , we developed a more environmentally conscious and better way of using cyanidation as a gold extraction process: the TriTank Takes on a triangular single tank design as opposed to the out-dated multiple circular design = multiple benefits including enhanced metallurgical performance, smaller land .
Outotec's cyanide leaching plants are available as gold adsorption directly from the process slurry in carbon-in-leach (CIL) and carbon-in-pulp (CIP) process In addition, dissolved gold can be recovered from the solution after solid-liquid separation by Merrill-Crowe and carbon-in-column operations
The CIL circuit consists of 6 tanks, ranging from 50’ high to 60’ high with a 24” drop between tanks The purpose of the CIL is to dissolve gold contained in the neutralized ore slurry by sodium cyanide leaching, and to adsorb the dissolved gold on to the surface of activated carbon
