Heap leaching. In heap leaching processes, crushed (and sometimes agglomerated) ore is piled in a heap which is lined with an impervious layer. Leach solution is sprayed over the top of the heap, and allowed to percolate downward through the heap. The heap design usually incorporates collection sumps, which allow the quot;pregnantquot; leach solution (i.e. solution with dissolved valuable metals) to be pumped

Heap leaching BioMineWiki Skellefte229;

Compared to stirred tank reactors, heap reactors form undesired gradients of pH and reagent levels. The reaction conditions in a heap varies from top to bottom, from core to surface and sometimes also locally in the heap. Still, the reaction conditions are less heterogeneous in a heap than in a dump or in situ leaching operations.
