In situ leach

In-situ leaching (ISL), also called in-situ recovery (ISR) or solution mining, is a mining process used to recover minerals such as copper and uranium through boreholes drilled into a deposit, in situ. In situ leach works by artificially dissolving minerals occurring naturally in a solid state. For recovery of material occurring naturally in solution, see: …

Considerations and potential economic advantages for the in-situ

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

Toward a more sustainable mining future with electrokinetic in situ

Metals are currently almost exclusively extracted from their ore via physical excavation. This energy-intensive process dictates that metal mining remains among the foremost CO 2 emitters and mine waste is the single largest waste form by mass. We propose a new approach, electrokinetic in situ leaching (EK-ISL), and demonstrate its applicability for a …
