Mohammad Rezaee is a PhD student at The University of Adelaide working on mineral carbonation, a promising carbon dioxide (CO₂) sequestration technology that can address the critical challenge of climate change. This process involves the reaction of CO₂ with naturally occurring minerals and industrial wastes, particularly those rich in divalent metal cations (e.g. magnesium, calcium and iron), to form stable carbonate minerals such as magnesite, calcite and siderite. Mohammad is investigating the carbonation potential of iron oxide minerals, such as hematite and magnetite, for CO₂ sequestration and mine backfilling applications. His project is exploring reaction mechanisms, optimising process routes, and assessing the feasibility of using iron-rich mining waste as feedstock for mine backfilling. The expected outcomes include the successful carbonation of mine tailings under predetermined experimental conditions and the development of a new mine backfill recipe using carbonated minerals. This innovative approach offers practical solutions for sustainable carbon capture and mine waste management. By integrating CO₂ sequestration with mine backfilling practices, Mohammad seeks to enhance the stability and safety of mining operations while contributing to environmental remediation efforts.
