    Oct 20, 2020 Compared with the CIP carbon slurry method, the CIL carbon leaching method saves the investment cost of 486,000 US dollars, reduces the backlog of gold in the production by 201.7 million US dollars, and deducts the 12,600 US dollars extra cost of activated carbon in the process , Saving and early recovery of funds of 675,100 US dollars.Oct 20, 2020 Compared with the CIP carbon slurry method, the CIL carbon leaching method saves the investment cost of 486,000 US dollars, reduces the backlog of gold in the production by 201.7 million US dollars, and deducts the 12,600 US dollars extra cost of activated carbon in the process , Saving and early recovery of funds of 675,100 US dollars.By cyaniding and carbon leaching the gold ore slurry simultaneously, CIL process lower the gold mining operation cost, and increase gold recovery rate to a ratio of 98. It has become the first choice of modern gold mining and beneficiation plant design.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.SGS metallurgists developed and continue to improve on these cost-effective, time-tested 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 Carbon-in-pulp.

    Carbon-In-Leach. Carbon-in-leach combines leaching with the carbon-in-pulp process, creating a single unit process operation. Usually this method is chosen when native carbon a high organics load is present in the gold ore, adsorbing the leached gold and preventing its recovery.Carbon-In-Leach. Carbon-in-leach combines leaching with the carbon-in-pulp process, creating a single unit process operation. Usually this method is chosen when native carbon a high organics load is present in the gold ore, adsorbing the leached gold and preventing its recovery.May 01, 2015 Activated carbon also consumes cyanide, so its effect has to be accounted for in the case of carbon-in-leach CIL or carbon-in-pulp CIP plant flowsheets. Since cyanide is an expensive reagent, often a major component of plant operating costs, it is important that the scale-up of cyanide consumption from laboratory to plant be representative.3. Carbon-In-Leach CIL The carbon-in-leach process integrates leaching and carbon-in-pulp into a single unit process operation. Leach tanks are fitted with carbon retention screens and the CIP tanks are eliminated. Carbon is added in leach so that the gold is adsorbed onto carbon almost as soon as it is dissolved by the cyanide solution.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.
