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

     

    Typical Turnkey Oxygen Supply System

    • PSA Oxygen Generator
      Produces 93% ±3% oxygen at flow rates optimised for CIL applications
    • Air Compressor & Dryer Set
      Refrigerated or desiccant drying systems, with filtration to ISO 8573-1 Class 1.4.1
    • Oxygen Receiver & Pipeline
      Stable, pressure-controlled delivery infrastructure with distribution headers
    • Custom Sparger/Lance Assemblies
      High-dispersion, anti-clogging spargers designed for rough slurry environments
    • Flow Monitoring Panel
      One panel per lance or multi-lance panel, top- or bottom-mounted to suit tank design
    • Safety Instrumentation
      Optional CO monitoring, oxygen flow limiters, and ASTM G88 compliant pressure control
    • Optional Booster
      For higher pressure supply where required
