Ores are heterogeneous materials from which metals are extracted. The heterogeneous nature of the ores makes extraction modeling challenging. New methodologies that characterize the relationship between valuable mineral grains and host rocks as well as the effect of comminution on that relationship facilitate improved modeling of leaching of crushed and ground ores in heap and tank leaching. These methodologies can be combined with additional techniques to account for heap leaching application scenarios that involve curing, point source solution application, and stacked ore compressibility in order to provide improved insights and accuracy in heap leach modeling. This presentation will describe the associated methodologies and techniques as well as provide a comparison of modeling and experimental results.
