Look before you leach: Dynamic Simulation of Heap Leach

THE HEAP LEACH PROBLEM . Heap leaching is a conceptually simple process but has several characteristics that make modelling the flowsheet quite complicated. Fundamentally, it is a slow process. There is a substantial time lag between stacking ore and producing the final product. During this time the soluble inventory builds

different leaching kinetics. When gold is directly exposed to the surrounding phase it has a fast leaching kinetic. On the other hand, gold attacked through ore porosity, like in heap leaching, exhibits slow dissolution kinetics. Figure 1 shows four different classes of gold, each one having a different leaching behaviour. One can see that gold
