Ore on the heaps is typically leached for a period of about 6–9 months, dependent on the time of year and weather conditions. The maximum gold extraction that can be achieved from Gedabek ore by heap leaching is around 70%, after which the ore heap is considered spent and ready for a new lift to be placed on it.

Shrestha et al. (2019) found that spent lime in leachate from bioretention plots did not affect heavy metal concentrations of Cu and Mn, reduced Al, Fe and Zn and slightly increased Ni (0.016 in spent lime vs. 0.013 mg L−1 in non-spent lime plots). Heavy metal concentrations of Cd, Cr and Pb in all treatments were <0.001 mg L−1.
