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.
Gold ore CarbonInLeaching (CIL) processing technology. SBM work together with the famous laboratory in China to design and deliver the gold leaching plant. It help the mine factory to extract a major part of the residual gold contained in gold ore or some tailings.
SGS metallurgists developed and continue to improve on these costeffective, timetested and proven processes. In each, activated carbon is used to extract gold from the cyanide leach solution. Such a carbon recovery system offers high recovery rates and lower capital and operating costs. These carbon recovery techniques include: Carboninpulp

Gold CIL production line Process Introduction. CIL (Carbon in Leach) process is the most efficient method to leaching and recovering gold from gold ore, The most protruding features is that leaching and adsorption are carried out at the same time, which greatly saves the cost of .
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.
A: If the plant is a CIP/CIL: The product can be fed into an agitated leach circuit to leach and recover the gold. If the plant is a Heap Leach/CIC: A small leach circuit can be set up to periodically feed highgrade solution to your existing strip plant, or depending on the capacity of your smelting furnace(s), the product can be smelted directly.
This is most important and a cost/benefit analysis of stripping costs Vs recovery % (in the leach circuit) will need to be performed. This will determine what the cut off point is for the number of strips/week to maintain generally low carbon loadings and lean and mean gold hungry barren carbon being returned to the bottom of the circuit.
The plant at Ity, Ivory Coast, is typical of KCA''s smaller modular plants. This photo shows the carbon column adsorption/desorption circuit. In these smaller plants, gold is adsorbed then desorbed from the carbon in the same columns using an alcohol strip. Carbon is replaced once per year.
The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. 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 .
nominal throughput of 500000, t/year through a hybrid carboninleach (CIL) plant to recover gold as bullion. Sulphide ores will be treated at a nominal throughput of 250,000 t/year through a conventional froth flotation plant to produce a coppergold concentrate. A block diagram showing the overall flow sheet is shown in Figure 1.
gold plant will be that of the leaching and carboninpulp circuit (CIP). The reagent and utilities operating costs associated with leaching, adsorption, elution and regeneration would typically make up some 15% of total operating cost, whilst the capital costs associated with these areas is about 16% of the total. Although not largest (capital and
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 well. Gold 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.
Gold CIL (Carbon in Leach) Process is an efficient design of extracting and recovering gold from its ore. By cyaniding and carbon leaching crushed gold ore slurry simultaneously, CIL process lower the gold mining operation cost and increase gold recovery rate to a degree of 99%.
Cyanidation carbon adsorption process is the most widely used in gold cyanide extraction process . The principle in brief is the carbon could adsorb liquid gold from cyanide solution . In 1970s, with the research and establishment of adsorption of carbon loaded with gold and the recovery of carbon discharge gold, make recycle the carbon and reduce the cost, and easy to process the gold ...
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
Activated carbon effectively removes the gold from the cyanide, as the gold is adsorbed into the pores in the carbon. This has spawned technologies such as CIP (carboninpulp), CIL (carboninleach) and CIC (carbonincolumns). More recently, SGS has lead the gold processing industry with the development of resinbased technologies.
Aug 14, 2019· Difference between CIL and CIP: * CIL is adsorbed while leaching; * CIP is first leached and adsorbed. 1. CIL (Carbon in Leach) Process is an efficient design of extracting and recovering gold from its ore. By cyaniding and carbon leaching crushed...
Carbon In Leach (CIL) Production Monitoring System It is a concern to know that the cost of retrieving the gold ore from deep below the surface of the ground, bring the ore body and waste material to the surface, crush and mill the ore to a fine slurry in order to process and recover the gold. These initial costs (at a guess)
Surface/underground mine cost models a variety of sizes/types: theoretical mining operations, flotation milling, carboninpulp, heap leach placer models.
The scope of the EPC contract included the delivery of a 2 mtpa CarbonInLeach gold processing plant and associated site infrastructure. The plant is designed to produce ~90,000 ounces of gold per annum. The first gold was poured in October 2017.
Aug 15, 2013· This video demonstrates the proposed process for mineral extraction being considered for GoGold''s Parral Tailings Project In Parral, Mexico.
