This research evaluated barrier materials for confining In-situ-recovery (ISR) operations within leaching boundaries and mitigating potential contaminant escape. Tailings-GGBFS binary mixtures were alkali-activated to form geopolymers. These composites exhibited high compressive strength (99 MPa) and low permeability (< 10?¹8 m2). The geopolymers showed significant stability in simulated downhole environments up to a depth of 2000 m, and incorporating mineral tailings improved their acid resistance. This performance meets and exceeds the functional requirements of ISR operations. | en_US |
