(Carbon-In-Leach), tanks where cyanide, oxygen and activated carbon are added. The oxygen and cyanide dissolve the gold, which is then absorbed onto the activated carbon. The carbon loaded with the gold is screened out of the slurry and processed further to make gold bars. To design the agitators to maximize the customer's profit.

Apr 16, 2014· My home made leaching tank was made @March 2014 for handling small quantity of Gold Stone,working together with some technique like Carbon System_Electrolysis System,many gold can come.
Approximately 85% of the gold is recovered in the plant. From the ball and/or autogenous mill, slurry is pumped to the CIL leach tanks where lime adjusts the pH, if necessary, and it is agitated for the desired period of time. Air is added to increase the reaction rate and shorten the leach time. Cyanide is added, typically in the first tank.
In the bottom of the tank is a French drain for removal of solution for processing. Wash solution and part of the French drain liquid are pumped to a head tank set at a height approximately double the depth of the ore bed. Hydrostatic pressure generated is used to inject solution into the ore bed.

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. The CIL process is frequently used when native carbon is present in the gold ore.
Agnico-Eagle's Pinos Altos Heap Leach in Mexico Heap leaching operations present lower operating costs compared to typical gold ore milling. So, cut-off grade for heap leaching is typically much lower than that of a milled ore. There certain economic considerations in the design of a heap leach operation in order to obtain optimum conditions. Costs
This leaching tank is designed to mix gold particles inside the slurry with carbon and cyanide in CIL plants.
The gold is recovered from this solution by electrowinning, zinc precipitation or refining technology such as the Mintek Minataur process.

On cyanide leaching of gold in the tank system, activated carbon is very important to use when in the process of recovery of dissolved gold, either by introducing direct to the Carbon In Leach (CIL) in tank or to the Carbon In Pulp (CIP) separately outside the tank after washing.
In CIP, the carbon is mixed with the cyanide leach solution, and agitated in the leach tanks, and agitated with the ore while the gold is being dissolved. This assures a rapid interface between the carbon and the gold loaded cyanide solution. Granular, hard carbon is used, in the size range of 10-16 mesh.
A high gold extraction (over 95 per cent) is achieved on cyanide leaching of the oxidised residue. Mintek has developed and refined the process fundamentals of the Bacox™ technology, and procedures for testing the amenability of refractory gold ores to bioleaching are well established.
now also commonly inject oxygen into the leach tanks to help accelerate the leaching process. Since oxygen is a key component in the above reaction, it increases gold recovery for a given residence time in the leach tanks. Usually, leach tanks are large and contain only cyanide solution and pulp.

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 and adsorption take place in the same tanks.

In the gold cyaniding process, leaching agitation tank is applied to leach and carbon-absorb ore pulps whose fineness is -200 meshes and whose density is less than 45%. Under similar circumstance, it is also applied to agitation and leaching in metallurgy, chemical and light industry.
settling out, bogging the tanks. Agitation also ensures that the gold cyanide complex ions forming on the surface of a gold particle are removed into the wider solution to allow 'access' on the gold particles' surface for more unreacted cyanide ions to leach more gold from the particle. Temperature Higher temperatures will increase the ...
