A key component of these models is detailed metallurgical accounting for the heap leach pads. Forte Dynamics utilizes the Opencontour software to capture where ore was loaded on the heap leach pad, when material was loaded, and the grade of the material placed on the heap leach pad (through time to feed into the model). This also allows us to quickly analyze what-if scenarios or other sensitives for our clients including changes in the mine plan, stacking plan, or preferential stacking scenarios for multiple heap leaching pads or process streams.
Forte Dynamics has developed these detailed heap leach recovery models for mining clients across the globe. These models have added value for our clients at all stages of the project, from preliminary design to operations. We assist clients with evaluating ways to bring heap leaching ounces forward and increase value for their assets. The ultimate goal for us and our clients is to bring the highest value to their mining projects by utilizing our expertise and dynamic modeling techniques.
Systems Modeling & optimization
Understanding the Crucial Interactions
In any mining project, the range of possible outcomes may seem infinite—and that’s why advanced mining and heap leach systems optimization is an area of emphasis at Forte Dynamics. Our experience in simulating dynamic systems—recovery, water balances, processing, or financial—enables a thorough analysis of expected behavior in complex systems. It also lets us quantify performance based on the uncertainties and sensitivities of key parameters. At Forte Dynamics we utilize various technologies to help our clients with heap leach operations, pumping systems, mine planning, and mineral processing.
We believe models are invaluable tools that allow us to investigate the details of system performance and identify the dominant factors that determine optimal metal recovery performance. We use modeling techniques for water balances, heap leach operations and optimization, financial analysis, process modeling, pumping and piping flow analyses, risk assessment, and probabilistic forecasting. At Forte Dynamics we develop these tools to help us and our clients gain a better understanding of complex mining systems.
Heap Leach Modeling
Forte Dynamics utilizes various software platforms to create detailed three dimensional heap leach recovery models for our clients. These models track the details and key process indicator recorded on our client’s sites to provide detailed forecasts and provide estimates on recoverable inventory for the various processing facilities.
