In the carbon-in-pulp process adsorption occurs after the leaching cascade section of the plant, and in the carbon-in-leach process leaching and adsorption occur simultaneously. In both processes the activated carbon is moved from one tank to another in countercurrent with the ore pulp until the recovery of the loaded carbon in the first tank.
Apr 21, 2017· Leached pulp and carbon are transferred in a counter current flow arrangement between a series of tanks, usually numbering 4 to 6. In the final tank, fresh or barren carbon is put in contact with ...
Carbon-in-pulp batch adsorption tests with minus 10- plus 20-mesh activated coconut carbon were made to estimate the equilibrium adsorption curve and to determine adsorption rates for gold in cyanide leach slurries of the ore.
Pulp flows continuously from the first tank to the last, while carbon is pumped counter current from the last tank to the first. The main difference between CIL and CIP lies in the extent to which gold is leached prior to carbon adsorption.

These methods are Carbon-in-Leach (CIL) and Carbon-in-Pulp (CIP). CIL and CIP operations involve several adsorption tanks placed in a series. Pulp flows continuously from the first tank to the last, while carbon is pumped countercurrent from the last tank to the first.

CIP (Carbon-in-pulp) / CIL (Carbon-in-leach) / CIC (Carbon-in-columns) SGS metallurgists developed and continue to improve on these cost-effective, time-tested and proven processes. In each, activated carbon is used to extract gold from the cyanide leach solution.
This chapter focuses on the advances made in the design and operation of carbon-in-pulp (CIP) and carbon-in-leach (CIL) plants. Most of the advances over the last few years have been in the area of carbon management.
activated carbon, which mixes with the leached pulp and flows countercurrent to the pulp in a series of tanks. The gold-bearing activated carbon is separated from the pulp by a mesh screen that blocks the carbon from passing through, while the smaller pulp particles are filtered away. CARBON-IN-LEACH
pulp in an environment appropriate for leaching in the CIP reactors. This additional leaching provides additional economic benefit. The CIL process 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 …
By replacing the Merrill–Crowe zinc cementation step, carbon-in-pulp (CIP) and carbon-in-leach (CIL) recovery provided a process that allowed the treatment of lower grade and problematic ores (e.g., high-clay ores), at lower capital and operating costs and higher metal recoveries.
The introduction of activated carbon to recover gold from cyanide leach solutions in the last quarter of the 20th century had a breakthrough impact on the economics of gold ore processing, as the ...
General Carbon-In-Pulp (CIP) Circuit Overview. In a Carbon-In-Pulp (CIP) operation, the majority of the leachable gold dissolves in the cyanide leach prior to the first carbon adsorption stage. These adsorption stages consist of tanks that can handle the carbon in the pulp/slurry.
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.
Activated carbon adsorbs dissolved gold from gold leach pulp complicated to be absorbed through the pores of this carbon.The most cost-effective procedure would be to make adsorption of the excavated gold on activated carbon, causing an easier solid-solid separation based on size.
Carbon in Pulp – gold mining. Carbon in Pulp (CIP) and Carbon in Leach (CIL) are methods for extracting higher grade ore from underground mining operations.

Carbon in pulp (CIP) is an extraction technique for recovery of gold which has been liberated into a cyanide solution as part of the gold cyanidation process.  Introduced in the early 1980s, Carbon in Pulp is regarded as a simple and cheap process.
Carbon In Pulp is the absorption of compounds into carbon Dicyano Aurrat. In the process of carbon-in-pulp adsorption occurs after the leaching of mineral ore slurry in a tank. And during the washing, the carbon-in-leach and adsorption occur …
