Fig. 7 Heap leaching- CIC process 6-2 CIL In the CIP process, carbon is charged in the adsorption stage. There is another method, where carbon is charged in the fi rst leaching tank. When the ore contains organic matter or clay, the gold and silver are adsorbed on these materials before they are adsorbed on the carbon granules. In such a case,

Dynamic Modelling of a Carbon-in-leach Gold Processing Plant
These models have been used for the simulation of CIP and CIL plants, with the aim of providing a tool for plants which can assist in decisions regarding plant design, operation and optimisation. The aim of this project was to develop and validate a dynamic model of the CIL section of a gold tailings retreatment plant.

Processing Gold Efficiently | E & MJ
For an agitated leach plant processing 2 g/mt gold ore, it requires a production rate of at least 5,000 mt/d of ore. Even in those cases, while the Carbon Converter has a payback of about one year, but it does not significantly move the economic needle since it increases gold production only 1% to 1.5%.".

Gold CIP and CIL process optimization in a capital constraint
Introduction. The well-known carbon-in-pulp (CIP) and carbon-in-leach (CIL) gold recovery processes are fairly robust. Considering the constantly changing characteristics of run-of-mine (ROM) ore, a robust process is in general a great advantage for a mineral processing plant. The disadvantage, however, is that because less input is required ...

Carbon-in-Pulp
In South Africa, the first CIP plant was commissioned in 1978 at Modderfontein 74 (Bailey, 1987). This was followed by more than a dozen plants between 1980 and 1983, treating a range of feeds. By the late 1980s, most of the equipment and processes that today characterize CIP technology were in place. By 2000, several hundred plants had been ...
