The North Heap Leach was commissioned in 1998 to process the initial high porous ore. Phase V Heap Leach pad construction was completed in 2009 and a further three phases of heap leach pad construction have been accounted for in the LoM plan. As the mine gets deeper so the percentage of weathered ore amenable to heap leaching decreases.

The chemistry involved in the dissolution of gold in the heap-leach cya- nidation treatment is the same as that for the agitation-cyanidation process.

Fluid flow is dominated by preferential flow in heap leach ore (caused by ore conveyance, stacking, sorting and dumping) (Orr, 2002), and may not follow common fluid flow laws (Darcy's law and Richards equation) because of voids that result from construction methods (Kampf et al., 2002). 3 Heap leach materials and characterisation

Apr 25, 2018Heap 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.

Heap leaching: In the open, cyanide solution is sprayed over huge heaps of crushed ore spread atop giant collection pads. The cyanide dissolves the gold from the ore into the solution as it trickles through the heap. The pad collects the now metal-impregnated solution which is stripped of gold and resprayed on the heap until the ore is depleted.

In a dynamic pad, the leached residues are removed from the leach pad at the end of the leach cycle, and fresh ore is placed to start a new leach cycle. In a static pad, the leached residues are left in place, and a fresh lift added on top.
