primary copper sulphide material. Since the leaching of chalcopyrite requires elevated temperatures, the generation and management of heat within the heap is crucial. Whereas many heap leach operations have utilised natural convection to supply air to regards to leach kinetics, acid balance, impurity control and thermal behaviour.
