Carbon in Leach Circuit CarboninLeach Circuit (CIL) For over a hundred years, miners have used dilute alkaline cyanide solutions (, sodium cyanide [NaCN] around pH 1011) to leach (dissolve) gold and other precious metals, from their ores. The gold is usually in .

With carboninpulp, 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. ... Less carbon fines in the circuit means less ...
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:

Then, it flows through a carboninpulp (CIP) circuit, followed by a MerrillCrow recovery system. The Macassa Mill was constructed in 1986, originally designed for a throughput of 725 tonnes per day. The mill underwent additional expansions and was upgraded to handle 2,000 tpd. Processing of ore at Macassa starts with crushing and grinding to ...
Nov 12, 2013· A semiempirical model was developed to represent a carbon in leach/carbon in pulp (CIL/CIP) circuit for recovery of gold and silver. The model uses a simple two rate representation of the leaching kinetics. Parameters for the leaching kinetics may be obtained by sampling the feed to a circuit and the tailings from each tank and assaying the ...
The process design of gold leaching and carboninpulp. 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 be that of the leaching and carboninpulp circuit (CIP) The reagent and utilities operating costs associated with leaching, adsorption, elution and.

CIP AND CIL CIRCUIT MODELLING The SGS carboninpulp (CIP) / carboninleach (CIL) modelling package is used to estimate the performance of a fullscale CIP or CIL plant and to derive the optimum design criteria based on the results of small scale experiments. It .
CarboninPulp (CIP) and CarboninLeach (CIL) processes have surface areas of about 1000 m²/g 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
During the testing and design of the Gold Fields'' Chimney Creek mine, it was found that a much higher carbon loading was possible with CIC (carboninsolution columns) than with CIP (carboninpulp). In an effort to keep the carbon handling minimized, an emphasis was put on forcing gold to the CIC circuit rather than the CIP.
A CIL circuit is a process of continuous leaching of gold from ore to liquid using a countercurrent adsorption of gold from liquid to carbon particles in a series of tanks. It concentrates gold from g/t in ore to 10000 to 15000 g/t on carbon, thus playing an .
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 rapidly to all the gold producing regions of the world. The percentage of annual global gold production by activated carbonbased processes grew from ...

Carbon in pulp Wikipedia. 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. [1] Introduced in the early 1980s, Carbon in Pulp is regarded as a simple and cheap process.
