Gold Heap-Leach Modeling Itasca International

Gold Heap-Leach Modeling Project Description. 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 mass-transport (hydrodynamic modeling) in a partially saturated pad, and quantitatively assess monthly production of gold-cyanide production (AuCN).
