Heap is the most attractive alternative for treating precious metal ores because of its low capital cost relative to other methods (Manning and Kappes, 2016). Heap leaching is designed to treat low grade gold ores containing 1.5 to 0.5 g Au/t and even lower concentrations in some cases (Palomo-Briones et al., 2016). Show abstract.

Design engineers have resorted to experience-based extrapolation from column-leaching data. Examples are Jansen and Taylor, (2002) (who advocate that the time for a given extraction in a column be multiplied by 1.25 to 1.50 and the final column extraction be multiplied by 0.95 to predict the heap performance); John, (2011) (who …

Heap leaching can take anything from a couple of months to several years. In the case of gold recovery, heap leaching generally requires 60 to 90 days to leach the ore, compared to the 24 hours required by a conventional agitated leach process. Gold recovery is also usually only 70% compared with 90% recovery in an agitated leach plant.
