CIL: Inter-tank carbon transfer
Carbon concentrations in the CIL and the transfer rate are the two main variables in CIL carbon design along with carbon activity (stripped carbon return). Carbon is normally transferred by pumping counter current to slurry flow with inter tank screens retaining the carbon in each tank.

Gold Project Ore Processing Plant Engineering Design
Project Description. The Mercur Gold Project consists of a 2700 tonne (3000 ton) per day carbon-in-leach (CIL) gold plant. In addition to the process facilities, the project incorporated the following: a) Upgrading and modifying of the existing 11 km (7 miles) of Tooele County road, from State Highway 73 to the project area.
CIL Gold Process, Equipment
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 ...

How to Differentiate Gold CIP & CIL Production Line
The continuous processes of gold recovery by adsorption on activated carbon in agitated tanks, namely the carbon-in-pulp (CIP) and the carbon-in-leach (CIL) processes, have been widely used since the 1970s. Carbon-in-pulp (CIP) is the sequential leach then absorption of gold from ore. During the CIP stage, pulp flows through several agitated ...
