The model considers the cyanidation reaction in a bed of uniformly sized spherical porous mineral particles, through which the leaching solution trickles. The leaching agents diffuse into the porous particles ...

view more200511 · To those of us in the gold industry, the question “What is Heap Leaching?” seems to have an obvious answer. In the simplistic sense, heap leaching involves stacking of metal-bearing ore into a heap on an impermeable pad, irrigating the ore for an extended period of time (weeks, months or years) with a chemical solution to dissolve the sought …
