The heap leaching process is modeled by production campaigns, whose start is determined by the availability of inventories of the crushing phase, the development of the campaign corresponding to the production of each heap, the limited production capacity due to available physical space, and the downstream storage capacity.
The most critical factor with feed material is its degree of hardness. The hardness of the material is typically measured in terms of compressive strength, ie the maximum force that the material can withstand before breaking. Hardness levels can range from that of concrete at 7000 psi to 50,000 psi for ores or other hard materials.
the kinetics of the sulfuric acid leaching process for multi-metal oxide copper alloy roasted in oxygen. Their conclu-sions indicated that a mixed kinetic shrinking core model could give a better description of the copper dissolution process in the system studied. Nicol [34] studied the leach-
