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.
In-Situ Leaching. Another more specialized mining technique is in-situ leaching (Figure 2), also referred to as in-situ recovery, or solution mining. This is perhaps the most economical of all techniques, but is only appropriate under certain conditions.
