The solubilized gold is simultaneously adsorbed onto coarse granules of activated carbon directly in the pulp in the so-called Carbon-In-Leach process CIL . The loaded carbon is treated at high temperature to elute the adsorbed gold into the solution once again.
Gold Leaching carbon in leach was developed from CIP Carbon In Pulp , is characterized by less process flow, timesaver in the leaching process, thus reducing the production expenditure. Besides, advanced extraction technology improving the efficiency of gold extraction. The CIL production line is wider use than CIP in the mineral industry.
Carbon in leach CIL is an important step in gold processing that involves simultaneous adsorption and leaching. While the mechanism of leaching and adsorption are well known, the effect of different operating and design parameters on the dynamics and performance of CIL circuit are not yet studied.
Process introduction : Gold mine CIL Carbon In Leach process, that is, gold extraction by carbon leaching, is a process in which activated carbon is added to the slurry and the leaching and adsorption of gold are carried out at the same time.
CIP mean Carbon In Leach differs from VAT leaching, and the main differences comes in three aspects; 1. How they works/operates -CIL there should be agitation mechanism to mixup the slurry not to
cyanide leaching gold recovery process - Carbon In Pulp can be used in areas where fine gold-bearing rocks are found. Sodium cyanide solution is mixed with f
A flowsheet, showing the Carbon In Leach CIL process This circuit utilizes a thickener, to maintain a constant percent solids in the ore feed, necessitating less water used in the process, smaller tanks and a smaller pond. It also gives much more control over the process that a conventional CIL plant without a thickener.
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.
