    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.
