Leaching and adsorption: pump slurry ore into the double-impellers leaching tanks, there are always 6-8 tanks working togheter; add cyanide solution into first one or two leaching tanks, add activated carbon into the rest gold leaching tanks; activated carbon adsorb gold and become the loaded gold carbon, the loaded gold carbon lift into the ...
Gold ore Carbon-In-Leaching (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.
Factors influencing the rate of gold cyanide leaching and adsorption on activated carbon, and their impact on the design of CIL and CIP circuits June 2010 Conference: Precious Metals Conference ...
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 ...
In the gold mining industry today, cyanide leaching is the prevailing method for solubilizing and recovering gold. Most of the new gold that is mined each year is processed via adsorption of gold cyanide onto activated carbon (Fleming et al. 2011). Typically, the carbon in pulp (CIP) or carbon in leach (CIL) process is used for gold recovery. These
Oct 20, 2014· The carbon has a very high affinity for the aurocyanide complex and adsorbs the gold out of solution resulting in very high loadings on the carbon (typically 1000-4000 g/t). At the end of the leach the loaded carbon is removed from the slurry and the adsorbed gold is stripped out at high temperature and pressure with sodium hydroxide and ...

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 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 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%.
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 high-grade silver.
May 01, 2011· A better alternative is to use models that adequately describe the rate of leaching of gold from a particular feed and the rate at which that gold loads onto activated carbon, and to derive optimum design criteria via an iterative process in which the impact of varying the plant design on metallurgical performance is examined.
Carbon-in-columns During this process, the cyanide leaching solution passes through columns filled with ore. The process is highly effective for removing gold from low grade ore. Resin Recovery Technologies Resin RIL (Resin-in-leach)/RIP (Resin-in pulp) In recent years, resin is replacing carbon as the gold recovery substrate of choice.
