OXYGEN GENERATORS FOR CIL GOLD MINE CIRCUITS
BOOST GOLD RECOVERY, REDUCE WASTE & IMPROVE SAFETY
FROM OXYGEN GENERATION TO ADVANCED SPARGER SYSTEMS – TURNKEY SOLUTIONS FOR GOLD PROCESSING
OVERVIEW
In Carbon-in-Leach (CIL) gold recovery circuits, dissolved oxygen plays a critical role in the leaching process. At Foxolution, we provide purpose-built oxygen generation systems and advanced sparger technologies designed to increase gold dissolution rates, improve plant efficiency, and minimise chemical consumption — while reducing operational risks.
We offer complete solutions including PSA oxygen generators, pipeline infrastructure, oxygen sparger assemblies, flow monitoring, and safety systems — all designed specifically for African mining conditions.
Why Oxygen Matters in CIL Circuits
✓ Increased Gold Recovery
Improved oxygen transfer increases the rate of metal dissolution, shortening leach times and increasing overall gold yield.
✓ Chemical Efficiency
Better oxygen availability allows more efficient use of cyanide, hydrogen peroxide, and other reagents, reducing costs and environmental impact.
✓ System Stability & Control
On-site oxygen generation eliminates supply interruptions and allows real-time oxygen control across all leach tanks.
✓ Safer Operations
Reduced risk of uncontrolled gas buildup or oxygen-starved reactions, with better pressure regulation and compliance with ASTM safety standards.
✓ Tailored Supply
From 50 L/min systems to multi-ton/day installations, our plants are configured to match your specific leach profile, altitude, and throughput.
Enhancing Gold Recovery Through Smarter Oxygen Distribution
At Foxolution, we’ve engineered a smarter way to monitor and manage oxygen flow across your CIL circuit — moving beyond basic pressure readings.
The Problem: Blocked Spargers = Downtime, Losses & Risk
Traditional pressure-based systems don’t detect early-stage nozzle wear or clogging, which leads to:
- Uneven oxygen delivery
- Accelerated erosion of remaining nozzles
- Lower gold recovery due to poor oxygen mass transfer
- Turbulence and potential ignition risks (ASTM G88 compliance failure)
The Foxolution Advantage: Visual Flow Monitoring Built-In
- Live Flow Visibility: Real-time insight into individual sparger performance
- Proactive Maintenance: Spot blockages or erosion before failures occur
- SCADA Ready: Optional integration with plant control systems for 24/7 monitoring
- Electronic Alerts: Pressure and flow deviation alerts for preventive action
