higher grade ore is crushed, followed by gravity separation, cyanide leaching with a carbon in-pulp circuit, and gold doré is produced on site. As required to meet the conditions of this permit, tailings may be subject a cyanide detoxification prior to disposal in the TSF. At
The carbon in pulp method is only used where tank leaching is utilized for the recovery of gold from the ores and this is not the case in most large gold mines today, since heap leaching is the lowest cost method for recovering gold from ores containing from a few grams to 5 or 6 grams per ton.

Gold mining equipment is used for processing, smelting, refining, purifying ... four main processes: floatation, amalgamation, cyanidation, or carbon-in-pulp. ... In this refining circuit, we can use electrowining cells, electrorefining cells ....
Recent developments in Carbon-in-Pulp (CIP) adsorption circuit technology have centred around the use of tanks arranged in a carousel mode of operation. The carbon is not transferred between stages, rather, feed and discharge points in each tank are moved to achieve counter current transfer1,2.
from heaps. Down flow carbon columns are rarely used for gold recovery, because they act like sand filters and are subsequently subject to frequent plugging. 2. Carbon-In-Pulp (CIP): Carbon-in-pulp operation is a variation of the conventional cyanidation process. Ore …

Carbon-in-pulp The ore is crushed, finely ground and mixed with the cyanide leach solution to form a slurry in an agitation tank. The activated carbon is introduced into the slurry and then removed by screening once it is fully loaded or “pregnant” with gold.
Gold is extracted from solution in the CIP circuit, which consists of six tanks. Loaded carbon is stored in two storage vessels. Acid and caustic are used in the carbon strip circuit and the loaded strip solution is pumped to a surge tank prior to entering the electrowinning circuit located within the refinery.
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 and advanced to the number 4 tank and so on by air lift.
To achieve this objective requires carbon with high adsorptive power which is a reflection on the inherent ability of the carbon, the efficiency of regeneration of the carbon and the residual values on the carbon when it is returned to the circuit. Additionally, the carbon must load well in the presence of co-absorbing materials, both organic ...
carbon in pulp processing plant. the most effect on the successful operation of a gold plant will be that of the leaching and carbon-in-pulp circuit (CIP) The reagent and utilities operating costs associated with leaching, adsorption, elution and regeneration would typically make.
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.
Dynamic simulation of the carbon-in-pulp and… Carbon-in-leach and carbon-in-pulp are continuous processes that use liquid and of the gold recovered in the loaded activated carbon that leaves the circuit,
Carbon circuit design allows for low quality carbon by increasing the carbon advance rate and setting an easily achieved and commercially prudent solution tails target of typically 0.02 ppm Au. These design criteria are important to ensure the commercial success of the gold operation in the first instance.
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.

RESOURCE BOOK 4444 Introduction The CIL (Carbon in Leach) circuit is an intermediate stage in the production of gold The process involves dissolving the solid gold particles into solution using a process know as cyanidation The dissolved gold in solution is .
Carbon in pulp - Wikipedia, the free encyclopedia. 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.
Carbon-in-pulp (CIP) 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 dissolve gold into solution.
Carbon is advanced such as to satisfy daily production requirements. An adequate amount of fresh or reactivated carbon is added daily to the last tank in the circuit. Carbon concentration in the pulp averages 24 grams of carbon per liter of pulp. Carbon loading, expressed in grams per metric ton of carbon is shown on Table 2.

available and recoverable in a conventional carbon in pulp (CIP) circuit, and consequently requires additional high intensity processing through a pyro-metallurgical process known as roasting. The processing plant treats ores from both the Kundana and Kanowna Belle Operations through separate processing circuits
A Smarter Approach to Carbon-in-Pulp (CIP) and Resin-in-Pulp (RIP) Applications. The Pumpcell circuit is a process route used for CIP or RIP applications. The Pumpcell represents a new approach to the design of conventional cascade CIP adsorption circuits.
CIP AND CIL CIRCUIT MODELLING The SGS carbon-in-pulp (CIP) / carbon-in-leach (CIL) modelling package is used to estimate the performance of a full-scale CIP or CIL plant and to derive the optimum design criteria based on the results of small scale experiments. It is a
