Gold recovery and cyanide optimization calculator

Discover how grade assumptions and hidden variability impact recovery and cyanide use

This interactive calculator illustrates the importance of grade management in optimizing the economics of gold extraction. Variability in ore necessitates making statistically robust assumptions about grade that contain enough safety margin to prevent excessive recovery drop while preventing excessive cyanide consumption. 

Exposing the hidden variability, reducing it, and adapting to the changing grade in real time can provide significant improvement in recovery and reagent consumption. 
In this calculator, you can compare the financial penalties of suboptimal grade assumptions and quantify the economic opportunity associated with variability management

Recovery-reagent trade-off calculator

This calculator evaluates the reagent and recovery loss when feed grade variability is hidden from you. Even in the best case scenario, you will incur some losses.

Having NTWIST independently validate our stockpile model gave us added confidence that our current estimates are sound, and that we’re well-positioned for the transition to stockpile-only operations.

NTWIST’s AI model increased potential profit in 42% of operating hours and corrected off-target conditions in another 17%. With further refinement, even greater stability and profit gains are expected.

Cory Kasinski

Former Head of Project Evaluations | Sherritt Technologies (via ALTA Conference)

We saw NTWIST’s platform as a strong fit for Clydach because it could improve process consistency without requiring disruptive infrastructure upgrades.
