Factors influencing the rate of gold cyanide leaching
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 carbon-based processes grew …

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 ...

The reason for using CIL/CIP is that sieve separation is much cheaper than filtration (as used in Merrill Crowe, often 2 stage filtration) or Thickening. Single stage thickening has only moderate success, so one probably needs counter …
Modeling and optimization of Carbon in leach (CIL) circuit …
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 …
