Cyanco Savings in Action:

Cyanide Optimization for Central Canadian Gold Mine

Property
High-grade underground gold mine with milling capacity of 3,000 TPD and total annual gold production of 100,000 oz.
Customer Need

After commissioning, Cyanco was asked to evaluate the cyanide consumption at the site to resolve the issues:

  • The mine was consuming unusually large amounts of cyanide.
  • Cyanide use fluctuated dramatically due to poor addition controls.
Results

Cyanco’s Cyanide Control System (CCS) was installed as run in parallel with the normal manual titrations to verify the analysis. After successful verification, the CCS was used to improve the mine’s cyanide addition control.

  • Cyanide was able to be added based on the real-time cyanide concentration data.
  • The cyanide fluctuations were minimized after a few months, eliminating overdosing.
  • By eliminating the cyanide fluctuations and reducing the cyanide setpoint, the site reduced its cyanide use by 32%.
