The target recovery of free gold for the ILR is plus 95%. Very high recovery rates on complex sulphide-related gold can also be expected.
The ILR will significantly improve gold concentrate security by replacing the tabling step and eliminating concentrate handling.
Low Operating Cost - High Automation
The system offers fully integrated electronic control of all critical leach parameters and is fully automated. Recovery costs per ounce are attractive.
Ease of Installation
This complete system can be retro-fitted to any grinding circuit. The ILR is modular and can sit adjacent to the plant. Controls easily integrate into existing plant distributed control system.
Bench Scale Test Work
The performance and cost for this simple system can be effectively predicted at bench scale in a laboratory. Reactor conditions can be optimised prior to full scale installation.
There are no high speed/high wear components in the system.
Only one pump and one drum drive.
Thorough mixing of solids / solution with the rotating drum, unlike vat leaching systems.
