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.

Granular activated carbon is often employed in the carbon-in-pulp (CIP) and carbon-in-leach (CIL) processes, where it is used in large tanks to adsorb gold from ore slurries. Powdered activated carbon, on the other hand, is ideal for carbon-in-column (CIC) systems, well-suited for the treatment of pregnant leach solutions.
CIL process is widely used in the mining industry and in particular, it is an integral part of gold extraction plant. It is a continuous process in which gold is recovered by cyanide leaching of ore slurry and simultaneous adsorption on activated carbon in agitated tanks (Figure 1).From the time CIL process was introduced in the gold processing, a lot of progress and …
Hydrometallurgical gold recovery processes play a pivotal role in the gold mining industry, contributing to more than 90% of global gold production. Among the array of techniques available, the Merrill–Crowe process, adsorption, ion exchange, and solvent extraction are central in extracting gold from leach solutions. While the Merrill–Crowe process and gold complex …
activated carbon has been the dominant process for gold extraction after leaching by cyanide in aerated alkaline slurries. The continuous processes of gold recovery by adsorption on activated carbon in agitated tanks, namely the carbon-in-pulp (CIP) and the carbon-in-leach (CIL) processes, have been widely used since the 1970s. Due to the economic
Activated carbon, which had been used for carbon-in-pulp cyanidation of gold ores for several years, is now playing an important role in the recovery of gold from heap-leach cyanidation effluents.
leaching of gold ores with dilute cyanide solutions and the recovery of gold and associated silver from the pregnant effluents by a carbon adsorption- desorption method.
Fluidised bed carbon columns can process solutions that contain as much as 2 to 3 wt% solids, thus making them well suited for heap leach applications which are often high in solids content. Jacobi offers a full range of carbon products to serve the gold recovery industry. This includes standard granular activated carbon grades (GoldSorb ...
Carbon-in-pulp and carbon-in-leach are continuous processes that have been wide used in gold extraction plants. These processes occur in a cascade of larger agitated tanks, and the carbon-in-pulp ...
This paper describes a new development in the cyanidation of gold ores, which we expect will result in a major improvement in the way many gold ores are treated. The process has evolved through work at Hazen Research, Inc. for Kamyr, Inc. and in brief, the consists of utilizing oxygen rather than air in the carbon-in- leach (CIL) process.
The carbon-in-leach process integrates leaching and carbon-in-pulp into a single unit process operation in which the leach tanks are fitted with carbon retention screens and the …
The CIL process The carbon-in-leach (CIL) process, illustrated in Figure 3 is a variation of the CIP process. In this process carbon is added directly to the leach circuit so that the leaching and adsorption processes proceed simultaneously. Capital cost is reduced, as only one set of agitators for both leaching and
Gold is a highly required material for a wide range of personal and industrial applications. The high demand for gold, together with the shortage of natural resources and high pollution potential of wastes generated during mining and ore processing activities led to search for alternative sources of gold. A possible source is represented by mine wastes resulting from …

Gold Recovery Process For gold recovery, water and a cyanide such as calcium cyanide, sodium cyanide, or potassium cyanide, are added to ore or scraps to form a slurry. The gold will leach out and mix with the cyanide into a solution. Activated carbon is then used to separate and store the gold, which is removed as the final step of the process.
