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 recovery/leaching. Some orebodies lie in groundwater in porous unconsolidated material (such as gravel or sand) and may be accessed simply by dissolving the uranium and pumping it out this is in situ leaching (ISL) mining (also known in North America as in situ recovery ISR). It can be applied where the orebody’s aquifer is

In-situ recovery—a move towards 'keyhole mining'

In-situ recovery (ISR, also referred to as in-situ leaching or solution mining) may offer such a step-change approach. ISR refers to the recovery of valuable metals from ore deposits by the circulation of a fluid underground and the recovery of the valuable metal from the fluid at the surface for further processing.

2021-4-22  Description . In situ leach or leaching (ISL) or in situ recovery (ISR) mining has become one of the standard uranium production methods. Its application to amenable uranium deposits (in certain sedimentary formations) has been growing in view of its competitive production costs

Impacts of Uranium In-Situ Leaching

2020-11-20  In the case of in-situ leaching (ISL) also called in-situ recovery (ISR), or solution mining the uranium-bearing ore is not removed from its geological deposit, but a leaching liquid is injected through wells into the ore deposit, and the uranium-bearing liquid is pumped to the surface from other wells. In-situ leaching gains importance for the exploitation of low grade ore deposits, for

Recent Trends in Copper In Situ Leaching —

In situ leaching technology because of its intrinsic advantages over conventional mining and milling is being considered as a viable option for recovering copper from both oxide and sulfide deposits. This paper reviews the development of copper in situ leaching, and discusses both commercial and experimental projects. Hydrometallurgical

Microbial leaching for valuable metals harvesting

2021-1-5  In situ leaching: In situ leaching means onsite leaching wherein ores reside within earth i.e., they are not taken out from rocks. In order to increase the permeability of water over rock, surface blasting is done after which leaching solution containing inoculum of Acidihiobacillus is pumped in or injected through pores or openings, fractures
