At the same time, they're constantly on the lookout for suitable and cost-effective equipment and systems for every heap-leaching project. Understanding the time-rate-of-recovery dynamics in heap-leach operations is mandatory for analyzing the financial performance of any mining operation. It's also a must for the successful execution of a project.

Heap leaching operations have evolved signifi-cantly over the centuries, ever since natural leaching was observed by Agricola and others in the 1550s. Modern heap leach facilities have become quite sophisticated and complex, and have to to deal with numerous metallurgical, geotechnical, and environmental challenges facing mines today.

Heap leaching is the most important method of hydrometallurgical copper extraction. Heap leaching is used for treating oxide and lower-grade secondary sulfide ores that contain up to ∼2% Cu. The ore is crushed to a uniform particle size (typically 12–50 mm), often agglomerated, and then stacked on large flat-topped heaps in a controlled manner.. Heaps are typically ∼7 m high …

Heap leaching (including bioleaching) is widely used for the treatment of low-grade copper ores [15,19], and the possibility of using it for Cu-Ni ore was also studied on an industrial scale [24].
