Aug 14, 2021· After the gold is leached out of the ore, it is typically absorbed onto activated carbon in processes such as Carbon-in-Pulp (CIP), Carbon-in-Leach (CIL), or Carbon Column CC). Once absorbed, the gold is stripped from the Carbon and the impregnated stripping solution fed into the electro winning process where the gold is recovered by electrolysis.

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. The high surface area is contained in the millions of pores of varying sizes, these being
Carbon-In-Pulp. 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 …
Oct 01, 1988· ADSORPTION OF GOLD BY CARBON In the carbon-in-pulp process, gold in solution is recovered from the pulp as follows. The pulp is contacted with the carbon, and the carbon and the pulp are then separated by screening. The carbon and the pulp are generally contacted in seve~al stages in the form of a cascade of adsorptlon vessels.
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 ...
CIP ( Carbon In Pulp) process is suitable for the treatment of oxidized gold ore with low sulfur content and mud content.It is unsuitable for the gold ore with high-grade silver as well. Generally, the proportion of gold and silver should not exceed 1:5. The best conditions for Carbon In Pulp process in China: PH=10-12, sodium cyanide concentration is not less than 0.015%, the particle size of ...
Carbon-In-Leach. 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 ...
- The carbon in pulp (CIP) process, - The carbon in leach (CIL) process and - The carbon in column (CIC) process. During the CIP process activated carbon particles are added to the leached pulp in a counter current circuit. The counter current principle is important because the amount of gold adsorbed on the carbon is in equilibrium with the ...
Jan 02, 2013· Following leaching, the pulp flows into the carbon-in-pulp circuit which operates in counter-current fashion. Usually five stages of adsorption are employed. Traditionally, 6 by 16 mesh activated carbon is added to the number 5 carbon-in-pulp tank …

Mar 13, 2020· Carbon pulp extraction process (CIP method and CIL method) is to put activated carbon into the cyanidation pulp, and the dissolved gold is adsorbed on the activated carbon, then the gold is extracted from the activated carbon.This process mainly includes the following steps: the preparation of leaching materials, agitation leaching and countercurrent carbon adsorption, gold-loaded carbon ...
activated carbon columns so the decision of using GAC instead of PAC is obvious. The next step is the selection of a granular activated carbon. Chemviron carbon was chosen due to it is usually used in Belgium water companies. There are a number of criteria that should be considered in this selection.
Carrier-in-Pulp (CIP) method, which is similar in principle with the Carbon-in-Pulp technology for gold recovery from ores, was proposed to recover these heavy metals from molten fly ash.
