CIL (Carbon In Leach), the gold carbon leaching method, is the carbon leaching method for gold extraction. Normally, the CIL process can concentrate gold from 2.5–3.5 g/t in ore to 2000 to 6000 g/t in carbon. The CIL gold process is suitable for beneficiating oxidized gold ore with low sulfur and mud content; Or process the gold tailings ...

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%."

The recovery of gold from heaps or dumps is often seen as a specialty area of gold metallurgy or, at the least, gold processing (Van Zyl et al., 1988). A requirement to be able to scale up from laboratory tests to field application has seen the need to develop specific procedures and techniques, in order to facilitate this and minimize risk.

The leaching of gold ores by acid solutions of thiocyanate produces two complexes, Au(SCN)2- and Au(SCN)4-. The reaction involves oxidation. It is believed that the addition of Iron III is a good oxidant. Trying to add oxygen is not a good option because the gold dissolution will be very slow.

The main difference between the CIL and CIP processes is that in the latter leaching and adsorption occur simultaneously, while in the former dissolution of the gold has already finished when adsorption starts. The CIL process is mainly used to treat ores containing organic matter and "preg-robbing" species, while the CIP is used in general ...
