In-Situ Recovery (ISR) In-situ is a Latin word that literally means "in the place." Unlike conventional mining methods, in situ recovery (ISR) removes the ore while leaving the rock "in the place."
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 (ISL), solution mining, or in situ recovery (ISR) involves dissolving uranium in the ground and pumping the solution to …

Abstract. The thermodynamic model of uranium in situ leaching process at the stage of acidification was investigated. It was demonstrated that in the frontal zone of acid leaching solutions reduction of U(VI) up to U(IV) was possible due to the behavior of oxidation–reduction processes with the ferrous ions involved.
