Chalcocite and oxide minerals leach rapidly under heap leach conditions. Bornite and covellite leach much more slowly. Depending on the mineralogy of a heap, leach times may vary from 90 days to three years. Chalcopyrite hardly reacts at all in heap leaching.
Heap and dump leaching are diffusion controlled never chemical reaction-rate controlled. The long leach times are due to the changes in the diffusion rate caused by the geo-technical characteristics of the ore especially the presence of clays, micas, and other platey and asicular-shaped particles and not the intrinsic rate of leaching Miller, 2002, 2008.
