Major Pollymetalic Mine in Australia
Improving process control in Tails Leach Tanks with 18 new virtual sensors and optimization recommendations


Customer Challenge
Real-time Control over Variables within Tanks
Metallurgists lack control over chemical conditions inside tanks (pH and Redux)
Gangue mineralogy can cause ‘gelling’ events
Laboratory assay results in every 4 hrs only

How We Helped
In-Tank Virtual Sensors and Optimization
Implementation of in-tank Virtual Sensors (VS) for density, slurry viscosity, and silica gel formation
Acid and Sodium Chlorate Dosing Optimizer
Material tracking influence (feed properties) and silica gel formation alerts

The Outcome
Metal Recovery Increased by 3% ($25M)
18 new Real-time outputs from Virtual Sensors
Additional production of 161.5 tonnes of U/year, worth of USD 25M/yr
Potential increase of 3% in Uranium recovery within the circuit by optimizing setpoints
