-by activated coconut carbon is a well proven process widely used to recover gold from slurry at cyanide leaching plants. In this research, modelling of adsorption of dissolved gold performed by using real CIP (carbon in pulp) plant data. For this aim, five kinetic models and the gold mass balance calculations were used together.
carbon-in-pulp (CIP) plant based on the Anglo-American Corporation (AAC) pump-cell technology at the Vaal Reefs Exploration and Mining Company's East gold plant which was operating profitably at lower head grades2. The AAC pump-cell technology is based on the carousel mode of operation2.

Sslurry at a rate of approximately 3.785 cu. m. per minute (1,000 GPM) is placed in contact with activated carbon. A simplified flow-sheet of the CIP Plant is shown in Figure 2. For years it has been known of the affinity of activated carbon to adsorb preferentially the gold and silver in cyanide complex form. This operation takes place in five circular tanks that provide a total pulp ...
The most well known carbon-in-pulp plant remains the prototype Homestake plant in Lead, South Dakota. Operating since 1973, this facility treats 2130 tonnes of ore per day averaging 2.7 g gold per tonne. Homestake has also operated small silver carbon-in-pulp plants at Creede and Cripple Creek, Colorado since 1979.
The Resin-in-Pulp (RnP) technology for gold and base metals recovers metals directly from slurries. The technology works on the same principle as Carbon-in-Pulp (CIP), which is widely used for gold recovery in a process where soluble gold from the leached slurry is adsorbed (loaded) onto carbon …
Carbon-in-leach and carbon-in-pulp are continuous processes that use activated carbon in a cascade of large agitated tanks, which have been widely used to recover or concentrate precious metals in gold extraction plants. In the carbon-in-pulp process adsorption occurs after the leaching cascade section of the plant, and in the carbon-in-leach ...
14 Stage, 330 meters-cube Carbon in Pulp Pumpcell Plant complete with 21.35 meters-squared Pumpcell Mechanisms. ... This pipe is referred to as the hydraulic seal, which ensures that pulp and carbon can not by-pass the screen, thus providing an effective seal having no moving parts.

A process for adsorbing gold from a leach pulp by means of activated carbon is described in which the leach pulp (the leach solution together with the subdivided gold bearing ore) is diluted to a specific gravity of less than that of the activated carbon and is subsequently passed upwardly through a multistage liquid/solid contacting column.
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. The Pumpcell is in essence a complete CIP plant incorporating a Pumpcell mechanism and ...
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
another material. Activated carbon is used to adsorb the gold out of solution. Because the cyanide ion forms very strong complexes with gold, it is the gold cyanide complex that is loaded onto the carbon rather than being deposited as metallic gold. Activated carbon, or charcoal as it is now less commonly known, is made from organic material such

The efficient design of carbon-in-pulp (C.I.P.) plants involves the integration of both process engineering and design engineering. Many recently constructed plants have not recognised the above interrelationship, and as such have incurred higher capital and operating costs than were in reality necessary. This has been compounded in some cases by slavishly following the design of...
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.

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. In the absorption stage, this solution flows through several agitated tanks containing activated carbon.
cycle. Carbon transfer in a countercurrent direction to the flow of pulp is achieved by moving the pulp feed and discharge points in the circuit rather than by physically pumping the carbon out of the tank. This has several claimed advantages: • There is no back mixing of pulp as occurs in a traditional CIP plant when carbon and pulp are pumped
