Leaching & Adsorption Resource Book

Carbon Adsorption Theory After the leaching process is complete, the soluble gold must be concentrated and separated from the process slurry. The method of recovery of gold from the process slurry is by carbon adsorption. Adsorption is a term used to describe the attraction of a mineral compound to the surface of another material.

Gold CIL Processing Plant

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 after gravity separation and mercury mixing.
