About the research project
Characterisation of mine wastes through lab- and field-based testing is standard practise in the initial stages of mine closure. However, long-term (> 10 years) disposal and storage of tailings and waste rock at surface exposes these heterogenous materials to natural weathering processes over the life-of-mine, and potentially in perpetuity at abandoned sites. Transformations in mineralogy, surface area, texture, and grainsize of mine wastes due to weathering processes may affect the long-term mobility of hazardous trace elements but may also create opportunities for remining wastes. This is especially true in regions of western Tasmania that receive a mean yearly rainfall of 2400 mm (BOM, 2021). Long-term changes need to be considered in the implementation of closure solutions as they will ultimately influence the effectiveness of closure designs and the feasibility of extracting additional value from these wastes. By assessing how various degrees of weathering alters the reactivity of waste piles over time, this project aims to inform mine closure designs and assess the potential for extracting further value from mine wastes. The knowledge generated from this project will provide insights to improving economic and environmental outcomes at active and abandoned mine sites in Tasmania and will influence mine closure planning globally.
This project will run in collaboration with the Central Sciences Laboratory, University of Tasmania, and the Department of Geological Sciences and Geological Engineering, Queen’s University, Canada.
