Simulation and Analysis of CarboninLeach (CIL) CircuitsSimulation results are first validated using previously published results. The validated model is then used to perform sensitivity studies on different parameters that affect the gold extraction process. The model can be used for controlling the operating parameters and to optimize the CIL circuit in order to achieve higher efficiency.
Gold Mining Process Development – Denver Mineral EngineersThe CIL process requires a larger carbon inventory in the circuit, which results in a larger inprocess tie up of gold. The larger carbon inventory can also result in higher carbon (and gold) losses through carbon attrition. CONCLUSION. Denver Mineral Engineers has had extensive experience with all of the commercially viable gold and silver recovery mining processes. We can suggest the optimal ...
Optimizing the Carbon Circuit at the YoungDavidson Mine ... · This resulted in recommendations for minor changes in the CIL flowsheet, which were successfully implemented in the plant.

CIP and CIL TestingGenerally in CIL tests we add carbon in the test vessel after certain period of time (depends on your ore, or cyanidation conditions, for example as lime preconditioning). Many people insist CIL/CIP tests must be done in agitated leach vessels. On the other hand many others claim bottle rolls deliver better results. My preference is bottle rolls. In fact there is a good paper, which will be ...
Insights From Simulation of a CIL/CIP CircuitThe results of these simulations highlight factors which need to be considered in the design and optimisation of a CIL/CIP circuit and provide an insight into deficiencies in performance and the best way to counteract them. INTRODUCTION The leaching of gold and silver by cyanide and countercurrent adsorption of the cyanide
Estimation of gold inventory in large carbon in leach ... · · The CIL tanks of a gold processing plant contain a significant inventory of gold that should be estimated to prepare the production balance for a gold processing plant. The estimation of the gold inventory in the CIL tanks requires sampling of the slurry in the tanks. The current method used to collect the sample was checked using repetitive samples and results show the .
