Mine to Heap/Mill Optimization

Forte Dynamics uses a holistic, systems approach to project optimization by analyzing and understanding the role of each component in the system - from resource modeling through process technology - in the context of maximizing our clients' returns over time.

We utilize detailed resource modeling and mine planning tools coupled with detailed metallurgical analysis to evaluate the various trade-offs for the project including comminution and processing. Forte Dynamics uses Opencontour to allow projected recovery to influence cutoff/cutover grades, providing a closed-loop methodology for optimizing the entire mine-to-recovered-metal system. Opencontour tracks individual blocks from the pit to discretized blocks on the heap leach pad with all of the pertinent ore properties, such as lithology and p80, to track recovery through time using detailed leaching hydrodynamics and kinetics. This allows our clients to evaluate risks and dependencies, with sensitivity analyses, to develop a more robust design and confident outcome. Our clients' objectives - whether metal recovery itself or financial results (NPV,IRR) - drive the "one size fits one" optimizations uniquely tailored to each site and situation.
