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

Precious Metal Heap Leach Design and Practice Ore-Max

Heap leaching had become a fairly sophisticated practice at least 500 years ago. Georgius Agricola, in his book De Re Metallica (publ. 1557) illustrates a heap leach with a 40-day leach cycle (Figure 1), which could pass in many ways for a modern heap leach
