The process design of gold leaching and carbon in pulp . 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 carbon in pulp circuit. More Details
Recent developments in CarboninPulp (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. One of the more successful developments

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 ...
Traditionally, when designing and optimizing gold inpulp recovery circuits (carboninpulp (CIP) and carboninleach (CIL)), the approach followed is to apply "rule of thumb" historical experience, intuition and empirical relationships – with the end result – large uneconomical margins of "safety" being included.
Printed circuit boards (PCBs) represent one of the most complicated and valuable components in electric and electronic equipment (EEE). ... The carbon in pulp (CIP) and carbon in leach (CIL ...
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 ...
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.
In Part 1 of this paper, the development of a semiempirical model of a carbon in leach (CIL)/carbon in pulp (CIP) plant for recovery of gold and silver was detailed. With appropriate practical parameters, the model was able to reproduce typical tank profiles for gold and silver contained in the solids, solution and active carbon.
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 .

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

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:
