Gold Locked in Complex Mineral Structures
In refractory gold deposits, gold is often encapsulated within sulfide minerals or associated with carbonaceous materials, preventing direct exposure to leaching reagents.
Oxygen as a Process Enabler
Effective oxidation is a prerequisite for liberating gold from refractory matrices. Oxygen availability, purity stability, and pressure control directly influence oxidation efficiency and downstream gold recovery performance.
Process Integration Focus
✔ Support for Pre-Oxidation Circuits
The oxygen generator is designed to integrate with pre-oxidation processes commonly used in refractory gold treatment, where controlled oxygen input is essential to break down sulfide structures prior to leaching.
✔ Enhanced Leaching Environment Control
By supplying stable and controllable oxygen, the system supports the creation of oxidative conditions required for aggressive leaching strategies applied to refractory ores.

One-Stop Solution
1)Process-Critical Supply, Not Utility Oxygen
Unlike conventional gold leaching applications, refractory gold processing requires oxygen supply with tighter control over flow stability, pressure response, and operational continuity.
2)Continuous and Predictable Oxygen Availability
The system is engineered to eliminate oxygen supply interruptions that could compromise oxidation kinetics or destabilize sensitive metallurgical circuits.
System Engineering Approach
Process-Driven Capacity Design
Oxygen capacity is engineered based on oxidation demand modeling rather than nominal plant throughput, ensuring oxygen availability aligns with metallurgical reaction requirements.
Dynamic Load Management
The system supports variable oxygen demand during different operating phases, including startup, steady-state oxidation, and process optimization periods.
Oxygen Generation Technology
Industrial PSA Oxygen Generation Platform
PSA technology is selected for its ability to provide continuous oxygen supply with controllable purity and flow characteristics, suitable for the sustained oxidative conditions required in refractory gold treatment.
High Availability Configuration
Redundant generation and control architecture are applied to support high system availability in metallurgically sensitive operations.
Automation & Process Control
Process-Coupled Control Logic
The oxygen system can be linked to metallurgical control systems, allowing oxygen supply to respond to process variables such as oxidation intensity and circuit load.
Stability-Oriented Control Strategy
Control philosophy prioritizes smooth oxygen delivery over rapid output swings, supporting consistent oxidation conditions and process repeatability.
Energy Efficiency & Cost Control
Energy consumption is optimized by aligning oxygen generation output with actual oxidation demand, avoiding excessive energy use during low-demand periods.
On-site oxygen generation provides cost predictability in refractory gold projects, where metallurgical uncertainty already introduces significant operational risk.
Deployment & Adaptability
Compatibility with Multiple Process Routes
The system can support different refractory gold treatment routes as selected by the mine, providing oxygen infrastructure flexibility during process development and optimization.
Expandable System Architecture
As ore characteristics or processing strategies evolve, the oxygen system can be expanded or reconfigured without fundamental redesign.
Reliability & Risk Mitigation
Designed for Metallurgical Sensitivity
System reliability is engineered to protect metallurgical stability, recognizing that oxygen interruption in refractory processing can have disproportionate negative impacts.
Industrial Safety Integration
Oxygen handling, pressure control, and safety interlocks are integrated in accordance with international mining and process safety standards.
