Adding carbon in the leaching tank; the carbon absorbs gold becoming gold loaded carbon. After adsorption, carbon screen separates the carbon and pulp. Desorption electrolysis of gold CIP process. Under high temperature and pressure, gold loaded carbon separates gold mud and carbon in closed system. Smelting of gold CIP process
CIP / CIL Interstage Screening . Carbon-in-Pulp (CIP) and Carbon-in-Leach (CIL) interstage screening solutions from Multotec Australia ensure even wear and extended life. Our precision-made symmetrical seamless wedge wire cylinders are spot-welded and ensure close tolerances on aperture sizes that allow for accurate cut points and minimal blinding.
Gold CIL (Carbon in Leach) Process is an efficient design of extracting and recovering gold from its ore. By cyaniding and carbon leaching crushed gold ore slurry simultaneously, CIL process lower the gold mining operation cost and increase gold recovery rate to a degree of 99%.
factor in the enhanced gold extraction in the presence of activated carbon for the ores. Kinetic models were developed for the leaching of gold from the ore, adsorption onto activated carbon and preg-robbing at the ore surface. A variable order empirical model of the Mintek form was used to describe leaching, while adsorption was
This facility includes nine tanks and associated screens arranged for cascade gravity flow; a pre-mix tank, a neutralisation tank, a leach tank followed by a Delkor trash screen, and six CIL tanks with inter-stage Kemix carbon screens, with discharge from the last tank flowing through a Delkor carbon safety screen.
Apr 27, 2017· DIY: Change Kenwood Start Screen Image. We show you how to change Kenwood start screen image for all the new Kenwood DDX9, DMX7 & DNX series multimedia units. This is useful to make your unit look factory fitted by displaying your vehicles logo at start up or simply want to put a cool image such as a photo of your car or girlfriend. 😀
1000T/D CIL production line In CIL (carbon in leach) process, activated carbon acts like a sponge to aurocyanide and other complex ions in solution. Hard carbon particles (much larger than the ore particle sizes) can be mixed with the ore and cyanide solution mixture.
The interstage screens prevents carbon going down the circuit. MPS and MPS(P) Interstage Screens are semi-submerged top exit type screens. The wedge wire screen is submerged under the pulp operating level allowing pulp to flow through the wedge wire screen apertures while carbon is retained.
Almost every imaginable type of screen has been tried for this application, with some types being much more successful than the rest. 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 ...

The carbon in the first CIL tank thus contains the highest grade of gold. 3. Carbon elution. Loaded carbon from the fist CIL tank is transferred by a slurry pump to the loaded carbon screen. The slurry is screened, the oversize carbon washed and gravitated to the vertical elution column.
CIL gold processing plant mainly consists of following steps: 1 The ore is first reduced in size (typically 90% passing 200mesh ) to ensure that all non-refractory gold is readily accessible for cyanide leaching, There are several variations of comminution circuits used in the gold leaching industry, such as: Multi-stage crushing, then ball milling circuits, typical of ball mill and hyrocyclones.
The process design of gold leaching and carbon-in-pulp circuits contaminants. These are removed by thermal regeneration of the eluted carbon, typically in a rotary kiln at temperatures of 650–750°C. Regeneration is carried out in a steam atmosphere to minimize carbon degradation due to oxidation. The eluted and regenerated carbon is screened ...
In carbon-in-pulp (CIP) and carbon-in-leach (CIL) processes, especially those utilizing pure oxygen instead of normal air to increase the overall efficiency of the cyanide leaching-adsorption process in the recovery of gold and/or silver from ores, the screen within each tank which surrounds the slurry outlet is kept clean. The cleaning action is accomplished by linearly reciprocating the ...

The gold CIL process is mainly used in the oxide gold ore, which has low grade of silver, it's more economize and has more benefit . ... the loaded gold carbon lift into the lifting screen by air lifter, the lifting screen separate activated carbon and slurry . ... the desorption of activated carbon and electrowinning the liquid gold are ...
In the absorption stage, this solution flows through several agitated tanks containing activated carbon. Gold absorbs onto the activated carbon, which flows countercurrent to the pulp, while screens separate the barren pulp from the gold-loaded carbon. Carbon-in leach (CIL) is a simultaneous leach and absorption process.
PDF | The ZADRA system is another elution process where gold that is adsorbed on to activated carbon is desorbed from the carbon by a reversal of the adsorption kinetics. The ZADRA elution circuit ...
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. CIL is slightly different from another gold extraction process called CIP or carbon-in-pulp process.
Generally CIL has 6-10 stages of tanks. The sodium cyanide(or some other leaching reagent) solution is added into the first tank, and gold starts to be leached, most CIL plant will add the activated carbon from the second tank to the last one. Carbon segregation screen is set in every absorption tank's outlet to separate the carbon and slurry.
Carbon-in-Pulp (CIP) and Carbon-in-Leach (CIL) processes have surface areas of about 1000 m²/g i.e. one gram of activated carbon (the amount of which will occupy the same space as the end of a person's thumb) has the same surface area as two football fields.
adsorbing onto activated carbon. Elution is the next step in the process, whereby the adsorption of the gold cyanide complex onto carbon is reversed. Loaded carbon is removed from the CIL circuit and the gold stripped from the carbon using a number of treatment steps. ... carbon screen where the carbon is screened from the slurry, which is ...
