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 ...
