Crushed ore agglomeration and its control for heap leach
For example, oxidized massive sulfide gold ores are so soft and permeable that even crushing below 75 mm does not increase gold recovery (e.g. Filon Sur ore body, Tharsis, Spain and Hassai Mine, Sudan). There can be serious issues in multiple lift and higher height heaps due to difference in ore properties.
