Goldabsorbs onto the activatedcarbon, which flows countercurrent to the pulp, while screens separate the barren pulp from thegold-loaded carbon.Carbon-in leach(CIL) is a simultaneousleachand absorption process. The simultaneousleachand absorption phases of the CIL process were developed for processinggold oresthat contain preg-robbing materials such as natural absorptivecarbon. These reduce thegoldyield by attractinggold…

Cyanidation, or the metallurgical process of extractinggoldfrom ore with cyanideleachingagents, has long been a primary method ofgoldbeneficiation.Widely used throughout the world, one incredible material helps to makegold recoveryfrom a cyanide solution possible; with its ultra-porous structure, activatedcarbon…
The LittleBald Mountain plantis typical of small ADR plants (Adsorption-Desorption-Recovery Plants) built by KCA. All operations needed for recovery of gold and silver from solution onto activated carbon, desorption, and electrowinning of metal bullion, are included in a …
The activatedcarbonis addedin leach, withgoldadsorption occurring nearly simultaneously withgolddissolution by the cyanide solution. CIL is often employed when nativecarbonis present in thegoldore and adsorbs the leachedgold, preventing itsrecovery.

Generally, the size range of the carbon is 10 mesh to16 meshand almost always no finer than 20 mesh.Coconut shell carbonis generally the preferred carbon for use in recovering gold from leach solutions.
IntroductionGoldCILPlantis one common process ingoldore dressing. Its famous feature is the simultaneousgold leachingand adsorption. This CIL method has highrecoveryrate and high degree of automation.Gold Carbon In Leaching leach
To further evaluate the process ofGold Recoveryby Gravity, Flotation andCarbon-in-LeachCyanidation, some cleaner tests with regrind of the bulk rougher concentrate, were conducted. Rougher flotation concentrates were reground to improveleachkinetics. The regrind sizes for these range of tests were not optimized. Regrind discharge sizes of between 24 to 64µm P80 were obtained. Thegold...

Thesecarbon recoverytechniques include:Carbon-in-pulp The ore is crushed, finely ground and mixed with the cyanideleachsolution to form a slurry in an agitation tank. The activatedcarbonis introduced into the slurry and then removed by screening once it is fully loaded or “pregnant” withgold.Carbon-in-leach
