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 ...

Modeling and optimization of Carbon in leach (CIL) circuit for gold
The CIL process concentrates gold from 2.5–3.5 g/t in ore to 2000 to 6000 g/t on carbon. Although the earliest process was in South Africa in 1890, CIP/CIL was first introduced in gold processing in 1949 at San Andreas (Honduras) (Marsden and House, 2006). As the ore grades have deteriorated from around 12 grams per tonne in 1950 to …

The CIL and CIP are slow processes, and in order to improve gold extraction and recovery, they occur continuously in a cascade of large agitated tanks. Figure 1 schematically shows the CIL or CIP circuit with three reactors. Note that the pulp flows by gravity from one tank to the next by overflow, the fresh activated carbon is added in the ...

CIP and CIL Testing
Generally 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 pre-conditioning). 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.
