Gold CIL production line Process Introduction. CIL (Carbon in Leach) process is the most efficient method to leaching and recovering gold from gold ore, The most protruding features is that leaching and adsorption are carried out at the same time, which greatly saves the cost of construction and operation.
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 carbonin leach (CIL) process. We refer to this improved process for all ores amenable to cyanide leaching as carbonin1each with oxygen or CILO.
Carbon Adsorption Theory After the leaching process is complete, the soluble gold must be concentrated and separated from the process slurry. The method of recovery of gold from the process slurry is by carbon adsorption. Adsorption is a term used to describe the attraction of a mineral compound to the surface of another material.
Gold CIL (Carbon in Leach) Process is an efficient design of extracting and recovering gold from its ore. By cyaniding and carbon leaching the gold ore slurry simultaneously, CIL process lower the gold mining operation cost, and increase gold recovery rate to a ratio of 98%.
We have the equipment and expertise needed to design the most efficient and costeffective cyanide leaching circuit for your gold processing operation. Our team includes world class professionals who have developed techniques such as CIP (carbon in pulp), CIL (carbon in leach), RIP (resin in pulp) and RIL (resin in leach).

Some of the products sold by the company in the category Gold Carbon are Gold Recovery Activated Carbon, Gold Leaching Process Activated Carbon.
It''s famous feature is the simultaneous gold leaching and adsorption. This CIL method has high recovery rate and high degree of automation. Gold Carbon In Leaching leaching process is a process that adds activated carbon to the slurry and simultaneously leaches and adsorbs gold, which is the preferred process for modern gold ore dressing.
The flotation tailings containing the unrecovered gold from the primary circuits are directed to the leaching plant and dissolved in an aerated sodium cyanide solution. The solubilized gold is simultaneously adsorbed onto coarse granules of activated carbon directly in the pulp in the socalled CarbonInLeach process (CIL).
Highly activated carbon is used in the dissolved gold recovery process, either by introducing it directly into the CIL (carboninleach) tanks or into separate CIP (carboninpulp) tanks after leaching. The activated carbon adsorbs the dissolved gold from the leach slurry thereby concentrating it onto a .
3. CarbonInLeach (CIL): The carboninleach process integrates leaching and carboninpulp 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.
leaching operations. Heap leaching provides relatively lowgrade, clear solutions from which the gold has to be recovered. In practice, carboninsolution (CIS) is generally used for the upgrading of the gold. With developments around goldselective anion exchange resins over the past few years and the recent commercialization of a number of ...
Gold CIL (Carbon in Leach) Process is an efficient design of extracting and recovering gold from its ore. By cyaniding and carbon leaching the gold ore slurry simultaneously, CIL process lower the gold mining operation cost, and increase gold recovery rate to a ratio of 98%.
heated at elevated temperatures in the presence of steam to create activated carbon. In gold recovery applications, activated carbon manufactured by Thermal activation is used. This process will be discussed in more detail. There are a number of steps in the production of activated carbon.
The APT TriTank is available as a small scale CIP/CIL cyanidation plant. The TriTank takes on a whole new revolutionary design making for a more environmentally conscious and even better way of using cyanidation as a gold extraction process, even at such a small scale. The design has multiple benefi
The CIL process The carboninleach (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 CIL process (carbon in leach) is an efficient method of extracting and recovering gold from its ore. By cyaniding and carbon leaching crushed gold ore slurry simultaneously, CIL process lowers the gold mining operation cost and increases gold recovery rate to a degree of 99%.
Carbonin 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 pregrobbing materials such as natural absorptive carbon. These reduce the gold yield by attracting gold meant for the activated carbon.
CIL stands for carboninleach. 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. CIL is slightly different from another gold extraction process called CIP or carboninpulp process.
Regardless of the leaching method – carboninleach (CIL), carboninpulp (CIP) or carbonincolumn (CIC) – valves need to provide reliable control for the liquid, gaseous and air flows. The presence of cyanide poses challenges to the process control and makes correct valve material selection essential.

tonne of carbon is achieved leaving as little as 0,01g of gold per tonne of solution in the tailings. There are essentially three process varieties that use carbon adsorption: The carbon in pulp (CIP) process, The carbon in leach (CIL) process and The carbon in column (CIC) process.
Jan 04, 2017· Metal recovery or concentration by adsorption on activated carbon has been the dominant process for gold extraction after leaching by cyanide in .
