Carbon-in-leach and carbon-in-pulp are continuous processes that use activated carbon in a cascade of large agitated tanks, which have been widely used to recover or concentrate precious metals in gold extraction plants. In the carbon-in-pulp process adsorption occurs after the leaching cascade section of the plant, and in the carbon-in-leach,

The CIL (Carbon in Leach) circuit is an intermediate stage in the production of gold. The process involves dissolving the solid gold particles into solution using a process know as cyanidation. The dissolved gold in solution is adsorbed onto activated carbon.

Gold Carbon-in-pulp (CIP) production is the sequential leach, then absorption of gold from ore. During the CIP stage, pulp flows through several agitated tanks where sodium cyanide and oxygen have been added to dissolve gold into solution. CIP process is suitable for the treatment of oxidized gold ore with low sulfur content and mud content.

18-02-2021· During startup of a countercurrent carbon adsorption system for processing heap-leach cyanide effluents, the first or lead column of carbon may adsorb all of the precious metal values. After the carbon has been in service for some time and carries about 20 ounces of gold per ton, a gradual break-through of gold will occur in the effluent from the first column and he

13-03-2020· Flow of Gold CIP Process. Carbon-in-leach (CIL) is a simultaneous leach and absorption process. The simultaneous leach and absorption phases of the CIL process were developed for processing gold ores that contain pre-robbing materials such as natural absorptive carbon. These reduce the gold yield by attracting gold meant for the activated carbon.

Activated carbon is a critical component in the beneficiation of gold ore, allowing this widespread process to occur because of its ability to recover gold from the gold-cyanide complex. Depending on the deposit, some silver ores may also be processed via cyanidation. Here too, activated carbon is the catalyst for recovery of this precious metal.

01-11-2015· 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.

Gold cyanidation is an established gold extraction process worldwide and carbon-in-leach (CIL), as an affiliate process, is the subject of extensive research and model development work. Most of the CIL process modelling efforts have focused on steady state scenarios for process design considerations. In this multiphase, counter-current process, however, steady state conditions

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.

Highly activated carbon is used in the dissolved gold recovery process, either by introducing it directly into the CIL (carbon-in-leach) tanks or into separate CIP (carbon-in-pulp) tanks after leaching. The activated carbon adsorbs the dissolved gold from the leach slurry thereby concentrating it onto a smaller mass of solids.

Usually, leach tanks are large and contain only cyanide solution and pulp. This slurry then flows into several carbon in pulp (CIP) tanks containing granulated carbon particles. The carbon captures the dissolved precious metal in solution through a mass transfer process known as adsorption. The carbon moves counter-current to the pulp
