Dynamic Simulation Heap Leaching Module. Dynamic modeling of flowsheets has been possible for many years, but METSIM has not been widely employed in that role. Other dynamic software simulation packages exist, such as speedup, which are targeted more towards the chemicals industry.
Heap leaching is an industrial mining process of separating precious metals, copper, and other minerals, from ores. It involves a series of chemical processes, through which the mineral ores are piled into the form of a heap, and a leach solution is spread over the ore surface to leach metal from the heap.
