Gekko Systems, in collaboration with CSIRO, proudly unveils the OLGA Mk3, an advanced evolution of the OnLine Gold Analyser engineered for unmatched precision, reliability, and operational efficiency.
As a flagship in Gekko’s real-time instrumentation suite, OLGA Mk3 delivers continuous, automated analysis of gold concentration in slurries and solutions. By replacing delayed manual sampling with real-time data, it empowers operators to optimise recovery, reduce losses, and make faster, data-driven decisions.
What’s New in OLGA Mk3
- Dual-size X-ray optics (9.7 & 11.4 keV) for sharper gold peak detection
- Improved interference rejection for arsenic, lead, and zinc
- Streamlined pipe flow design, replacing the legacy agitated tank system
- Simplified X-ray window access for faster maintenance
- Rapid window changeovers
- Manual sampling option for added flexibility
Factory-Tested Performance
- Detection limit: As low as 0.02 ppm gold in solution
- Accuracy: Error reduced from ~84% at 0.02 ppm to 10% at 0.10 ppm
- Flowrate calibration: Assay variance cut from 44% to 13%
- Uptime: 98% availability and 95% utilisation over six weeks
- Safety: Validated X-ray safety redundancies under elevated temperatures
OLGA Mk3 also introduces multiplexing, enabling simultaneous monitoring of multiple streams—such as cyclone overflow, flotation feed, tails, and electrowinning circuits. This expands its diagnostic reach across the plant and supports broader metallurgical optimisation.
Engineered for precision, performance, and peace of mind, OLGA Mk3 sets a new benchmark in gold process monitoring.
