Difference Between Carbon In Leach And Carbon In Pulp

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 The process design of gold leaching and carbon-in-pulp circuits. carbon-in-pulp circuit CIP. The carbon-in-leach CIL process, illustrated in Figure 3 is a variation of the CIP ...

What is an Interstage Screen Multotec Canada

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

PDF Gold CIP and CIL process optimization in a capital

The carbon in pulp CIP and carbon in leach CIL processes became firmly established in the gold mining industry in the 1980s, initially in South Africa and Australia, from where they spread ...

The leaching and adsorption behaviour of gold ores

adsorption onto activated carbon, these effects include competing metal-cyanide complexes, preg-robbing and the mineralogy of the ore. This thesis considers these areas from an experimental and modelling viewpoint. In this research it is shown that a variety of metal-cyanide species can be used to leach gold from certain refractory ores.

Gold Recovery Kalimati Carbon

A major use of activated carbon in mining is in gold recovery , where granular activated carbon GAC is used for adsorption of the gold-cyanide complex in carbon-in-pulp CIP and carbon-in-leach CIL systems, or in carbon-in-column CIC systems after a heap leach operation carbon.

ACTIVATED CARBON IN GOLD RECOVERY Kemix

Carbon-in-Pulp CIP and Carbon-in-Leach CIL processes have surface areas of about 1000 m g i.e. one gram of activated carbon the amount of which will occupy the same space as the end of a persons thumb has the same surface area as two football fields.

Gold Mining Process Development Denver Mineral Engineers

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.

Oxygen Sparging Improves Gold Leaching

The dissolution of gold through cyanidation, either Carbon in Pulp CIP or Carbon in Leach CIL, is an oxidizing reaction. Generally added oxygen, in the form of dissolved oxygen in solution, improves the process as the rate of gold dissolution is directly proportional to the amount of

Gold Carbon In Leach Plant Updated January 2017

Each carbon leach tank has a interstage screen in it for carbon retention. Slurry can gravity flow between tanks or be pumped. Typically there are 4 to 6 tanks in series. From the first tank, the loaded carbon is pumped using a recessed impeller pump to not degrade the carbon, or another suitable type of pump, to a loaded carbon screen, where ...

carbon and gold in carbon in pulp CIP and carbon in leach CIL applications. However, this reactor design also has some drawbacks. The strong correlation between solids particle size and the required mixing power for solids suspension makes it difficult to achieve a

Carbon and Resin Technologies for Gold Recovery Mining

These carbon recovery techniques include 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. Carbon-in-leach

FLOWSHEET DEVELOPMENT FOR GOLD OREBODIES

pulp in either a carbon-in-leach CIL, or a carbon-in-pulp CIP plant. In both these cases, the coarse granules of activated carbon are mechanically mixed with the pulp in an adsorption tank, and gold-loaded carbon granules are separated from gold-depleted pulps by screening.

Activated Carbon in Gold Cyanidation

In the gold industry, the use of activated carbon to separate gold from cyanide leaching solutions has become an industry standard for efficient gold recovery in Carbon-in-Leach CIL, Carbon-in-Pulp CIP and Carbon-in-Column CIC operations.
