  • Underground Mine Design Itasca International

    Gold HeapLeach Modeling. Itasca developed a numerical model to estimate gold (Au) production from heapleach operations. The objective was to simulate Au heap leaching using a model based on fluid flow and masstransport (hydrodynamic modeling) in a partially saturated pad, and quantitatively assess monthly production of goldcyanide production (AuCN).
