Abstract

Language:

The In Situ Recovery (ISR) mining method consists in mining ore by in situ chemical leaching with acid or alkaline solutions. Numerical modelling of the interaction between solution and rock is examined in order to improve the management of this process. Three different phenomena have to be taken into account in a numerical reactive transport simulation of uranium ISR mining: (1) the geochemical reactions occurring during leaching, (2) the physical processes of advective and diffusive transport, and (3) the mineralogical transformations that can take place in the uranium-bearing rocks. This study utilizes reactive transport modeling to analyze the efficiency of uranium extraction and to evaluate the impact of these processes on the overall ISR operation. Results indicate that an accurate representation of the geochemical dynamics and flow characteristics is essential for optimizing uranium recovery while mitigating environmental impacts. The findings underscore the importance of refining modelling techniques to enhance ISR mining practices and suggest further investigations to validate and improve these models in field applications.
