In situ leaching of copper: Challenges and future ...
2015-10-1 Applicability of in situ leaching is limited to deposits where sufficient permeability exists and where the copper and gangue mineralogy is amenable to leaching. A key challenge from past projects is establishing uniform contact between the fluid and the formation in fractured environments, particularly if fractures become blocked by gypsum and jarosite precipitation during leaching.

One of the primary challenges of intact in situ leaching in fractured deposits is spatial variation in permeability. Naturally fractured systems have high permeability in areas of high fracture density or wide fracture aperture, which causes the leach solution to channel along these preferential pathways.

In-situ leaching recovery of copper: what’s next ...
In situ leaching (ISL) involves the application of a specific lixiviant to dissolve en masse minerals within the confines of a deposit or in very close proximity to its original geologic setting. Currently there is considerable interest in applying ISL technology to recover copper.

In situ leaching of copper ores. Part 2
Hydrometallurgical extraction of copper by in situ leaching needs to refer to disciplines such as solution chemistry, hydrology, geology, geochemistry, and rock mechanics. Both physical and chemical parameters must be integrated to successfully predict in situ leaching performance. In this review, data from past copper in situ leaching projects are assembled, with a focus on recovery with and ...

innovations and future directions: A review Heap leaching ...
2017-12-5 copper heap leaching is used in parallel with concentration of higher grade materials by flotation to still extract value from materials which are below the cut-off grade. Similarly, gold mines use agitated leaching for high-grade ores and heap leaching for marginal grade ores that otherwise would be considered waste rock.
