Heap leaching is one of several alternative process methods for treating precious-metal ores and is selected primarily to take advantage of its low capital cost relative to other methods. Heap leaching involves stacking of metal-bearing ore into a heap on an impermeable pad, irrigating the ore for an extended period of time with a chemical solution to dissolve the sought-after metals, and collecting the leachant as it percolates from the base of the heap.
