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.
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.

Carbon-In-Leach (CIL) The CIL process integrates leaching and CIP into a single unit process operation, in which the leach tanks are fitted with carbon retention screens and the CIP tanks are eliminated. The activated carbon is added in leach, with gold adsorption occurring nearly simultaneously with gold dissolution by the cyanide solution.
was used to remove gold from a cyanide solution by using zinc dust to precipitate gold from its solution. 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.
This is based on a targeted 85 percent gold recovery rate during those first three years, using Aachen processing technology, adopted to reduce operating costs and utilize a carbon-in-leach plant.
This article serves to discuss the fundamental aspects of gold recovery utilizing the Carbon-in-Pulp or Carbon-in-Leach processes. The purpose is to describe in simple terms what activated carbon is all about and how it adsorbs gold. The understanding of the mechanism of gold adsorption is important because the CIP/CIL processes work as
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 (carbon-in-pulp), CIL (carbon-in-leach) and CIC (carbon-in-columns). More recently, SGS has lead the gold processing industry with the development of resin-based technologies.
Whether your final flowsheet uses carbon or resin technologies, the data gathered by SGS will enable you to make important operational decisions and provide capex and opex information for your feasibility study. Carbon Technologies to Recover Gold CIP (Carbon-in-pulp) / CIL (Carbon-in-leach) / CIC (Carbon-in-columns)

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.
Gold Carbon In Leach Plants Updated January 2017. Gold Processing Plant, Carbon In Leach (CIL) Plant. A Carbon In Leach Gold Recovery Plant. This plant processes 4 million tons of ore per year with an average gold content of 0.043 ounces of gold per ton of ore. Approximately 85% of the gold is recovered in the plant.
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%.

Factors influencing the rate of gold cyanide leaching and adsorption on activated carbon, and their impact on the design of CIL and CIP circuits
slurry is passed counter-currently to activated carbon through a 5 stage heated leach circuit. • Gold is desorbed from the carbonaceous material in the first 3 stages at upto70 C. then is adsorbed by the activated carbon in the final 3 stages after cooling in a heat exchanger and by cooling water addition
The APT TriTank is available as a small scale CIP/CIL cyanidation plant. The TriTank takes on a whole new revolutionary design making for a more environmentally conscious and even better way of using cyanidation as a gold extraction process, even at such a small scale. The design has multiple benefi
The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. 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 …
