Carbon-in-Leach (CIL) Overview
Gold Recovery Carbon · CIL
YX & NS Series Carbon Application
In the CIL process, activated carbon contacts slurry in the same tanks as leaching. YX & NS Series Activated Carbon support large-scale throughput with robust performance and efficient carbon transfer.
APPLICATION DETAIL
In the CIL process, activated carbon contacts slurry in the same tanks as leaching. YX & NS Series Activated Carbon support large-scale throughput with robust performance and efficient carbon transfer.
Carbon-in-leach (CIL) combines cyanide leaching and carbon adsorption in the same series of agitated tanks, shortening the process and reducing in-circuit gold inventory. Activated carbon must withstand agitation and continuous transfer.
Key Benefits
- Leaching and adsorption take place in the same tanks
- Large tank configurations for high-throughput plants
- Choose G11 for hardness or G12 for higher activity based on ore conditions
- Supports an integrated elution, electrowinning and carbon regeneration circuit
