Gold on carbon/gold in solution ratios of >1000:1 are achievable in many cases. The distribution of that carbon between the stages (within reason) is irrelevant. The concentration of carbon in the pulp varies with the size of the tanks, so it is irrelevant. Gold extraction efficiency is determined by:

1.Understanding the concept of CIP or CIL gold processing plant. CIP (carbon in pulp): after you leaching the gold ore pulp in the leaching tank by cyanide, then feeding the leached ore pulp into the adsorption tank for adsorp the gold by active carbon. CIL (carbon in leach) : feeding the ore pulp in to the leaching-adsorption tank, then leaching and adsorp the gold at same time at the ...

The preg robbing components can either be fine clays or naturally occurring carbon within the ore. If a carbon-in-pulp (CIP) circuit were to be utilized for the processing of ore containing preg robbing components, then part of the gold dissolved in the leaching stage will be adsorbed by the carbon or clays present in the ore and result in gold ...

A gold ore processing plant that processes 2000 t/d of a gold ore assaying 7 g/t may have a gold inventory of more than 140,000 g of gold in gravity concentrator bins, carbon in pulp tanks and in the electrolysis circuit.This is equivalent to the mass of gold that fed the circuit during 10 days of operation.The change of inventory may therefore strongly impact on the production …

CIL (carbon in leach) : feeding the ore pulp in to the leaching-adsorption tank, then leaching and adsorp the gold at same time at the leaching-adsorption tank. In fact, the CIP and CIL do not differ so much.

By the late 1980s, most of the equipment and processes that today characterize CIP technology were in place. By 2000, several hundred plants had been built. 2. Activated Carbon. ... volumes of the leach and adsorption tanks, pulp density, carbon concentration; ...

Carbon In Leach (CIL) and Carbon In Pulp (CIP) are two commonly used methods in the gold extraction process. ... After leaching, transferring the pulp to a series of adsorption tanks where activated carbon is sequentially added to adsorb the dissolved gold. ... 2.2 Equipment Configuration. CIL: Since leaching and adsorption occur in the same ...

The carbon-in-leach process integrates leaching and carbon-in-pulp into a single unit process operation in which the leach tanks are fitted with carbon retention screens and the carbon-in-pulp tanks are eliminated. The activated carbon is added in leach, with gold adsorption occurring nearly simultaneously with gold dissolution by the cyanide ...

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. The main difference between CIL and CIP lies in the extent to which gold is leached prior to carbon adsorption.

Carbon in pulp process. 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 …

mm which allows pulp to flow through and out of the reactor whilst retaining the carbon in the reactor. The gold aurocyanide complex in the aqueous phase is readily adsorbed onto the activated carbon. By the time the pulp leaves the last tank in the adsorption cascade the concentration of gold in the aqueous phase is typically between 0.001 and ...

the commonly used C.I.P process involves the use of a series of tanks or pachucas in which the pulp and carbon are contacted countercurrently. This is generally achieved by having a steady flow of pulp through the series of adsorption vessels coupled with the periodic transfer of carbon, usually with its associated pulp, in a countercurrent direction.

The first 1 ~ 2 tanks are cyanidation pre leaching tanks, and the next 7 ~ 8 tanks are leaching adsorption tanks. 4.Different dosage of activated carbon. Compared with CIP process, CIL process uses more activated carbon, the contact time between activated carbon and pulp is longer, and the wear of carbon is larger.

Assuming that a gold ore has been effectively ground to ensure maximum economic liberation of gold, the circuits that will have the most effect on the successful operation of a gold plant will …

With carbon-in-pulp, the ore is finely ground and the gold is solubilised using a cyanide leach in a series of tanks. The granular activated carbon is added to the leached slurry, where the carbon adsorbs the gold from the slurry solution and is then removed from the slurry by coarse screening. Often a series of five or six agitated tanks are ...

Lower carbon inventory. Interstage screens retain carbon in the tanks. Carbon in leach Combining leach and adsorption into a single process, CIL circuits introduce cyanide, ore pulp, oxygen, and carbon at the same time. Sizing of the tanks is calculated based on the time needed to complete ore leaching, usually 24-72 hours.

When carbon is being educted to the feed hopper the Linotex valve is fully closed and the 50 mm (2 in.) gate valve to the overflow (slops tank) is fully open. When excess water to the carbon is drained away the Linotex: valve is opened. The 25 mm (1 in.) valve with the quick-disconnect fitting is used when carbon hangs up in the hopper.

The pulp flows continuously from the first tank to the last, while the carbon is transferred countercurrent from the last tank to the first. The contacting vessels are mechanically agitated and are designed to allow a pulp residence time of 60 to 80 minutes.

Acid washing has proven to be a very cost-effective means of maintaining the activity of activated carbon. During operation, carbon will typically become fouled due to an accumulation of precipitated mineral salts.
