Stochastic Optimization of a Low-Grade Iron Ore Mining Complex
A case study led by the KPI Mining team focused on a low-grade deposit, where the conventional deterministic plan revealed significant risks, particularly related to sulfur contamination and the forecasted iron head grade. Additionally, the potential for dilution and ore loss was identified. Using the stochastic approach, the team developed a more robust mine plan, from which risk-resilient operational phases were designed. Ultimately, re-optimization within phases was conducted (again using the stochastic method) to ensure maximum value. The final designed mine plan showed 25% higher NPV compared to the conventional base case.
