Gold recovery and cyanide optimization calculator

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
