Exploring all aspects of mine waste and tailings management. The 2023 Mine Waste and Tailings Conference, co-hosted by AusIMM and The University of Queensland, welcomed delegates from across the globe to explore all aspects of life cycle waste rock and tailings management, from site selection and design to post-closure care, and also addressed current and future challenges impacting mining systems re-engineering. The conference proceedings centre around the demand of innovation and evolution of mine waste and tailings management through the key themes of: commingling of tailings and coarse wastes; emergency response; geochemical and geotechnical testing of mine wastes; governance and standards; importance of site climatic, topographic, seismic and social settings; innovative mine waste management; licence to operate; mine closure; monitoring and surveillance; operational aspects and case histories; selection of parameters for TSF and WRD design; tailings dam breach and runout assessment; tailings dewatering and placement; tailings liquefaction and seismic response; water and AMD management.
