In-situ recovery (ISR) can be a promising low-cost solution for extracting low-grade critical minerals or metals, such as copper, from ore deposits without traditional mining methods and a viable approach for decarbonising mining and processing. ISR injects the lixiviant into ore deposits to dissolve a target mineral and recover it from the production well. ISR is a low entry mining method, which has lower environmental impacts, consumes less energy for rock comminution and handling, and provides a safer working environment than traditional mining methods. However, due to the complex solid-fluid interactions and coupled hydro-chemical reactions involved, more studies need to be carried out to understand the fundamental mechanisms for optimising recovery efficiency under in-situ conditions. This project aims to develop a multiscale numerical model to study multiphase interactions and hydro-chemical interactions for the ISR of copper at both nanoscales and microscales. Molecular dynamics (MD) will be used to study the thermodynamic and kinetic properties of the multiphase system. Then, the MD results will be applied to a pore-scale model that couples the reactive flow, diffusion, and mineral deformation. The proposed multiscale and multiphysics model will be used to study the in-situ leaching process systemically to gain new knowledge for optimising the recovery efficiency and better control of the leaching solution.
