HyperSparge™ gas jet and microbubbles mean high gas utilisation and faster leach kinetics.

The HyperSparge™ is a proven and cost-effective system for delivering air, oxygen or other process gases into tanks or vessels for leaching or oxidation processes. The HyperSparge™ is a gas sparging technology that uses an alloy steel injection lance fitted with a hard-wearing ceramic nozzle to inject a concentrated supersonic jet of gas into the process solution or slurry. The supersonic gas jet enters the process stream at velocities in excess of 400 m/s, creating a region of very high local shear, resulting in very efficient mass transfer.

HyperSparge™ advantages

• Increased leaching rates
• Lower oxygen consumption
• Live insertion, removal and maintenance - no process downtime
• Improved safety
• Lower cyanide use in CIL circuits
• Simple design and construction
• Robust, long life materials
