Heap Leach Recovery Model

Determine the recovery sum of each block cell to assess performance throughout the heap leach pad.

A software algorithm identifies areas where it is most optimal to leach, based on metrics (such as solution-to-ore ratio) to maximize metal recovery and reduce solution waste. This information enables mine operators to make decisions regarding loading scenarios to improve leaching performance across the pad.

The complexity of these models used to require hours of computation in the past. Opencontour utilizes GPU technology (parallel computation) to reduce total computation time to minutes allowing users to calibrate or run many iterations on a plan.

The heap leach utility can also track and plan leaching operations over time. Users can enter primary and secondary leach cycle dates and durations into Opencontour to follow irrigation levels throughout the leach pad. This can be done by drawing polygons around the various irrigation areas in the model and applying the dates and levels of irrigation.
