Estimates of waste volumes produced from mining activity exceed 13 billion tonnes (Bt) annually (Valenta et al, 2023). In this case, we refer to mine waste as that produced from mining and processing activities and subsequently stored in a waste storage facility such as a tailings dam, integrated waste landform or similar. We do not include other forms of waste from the mining industry, such as wastewater, truck tyres, and other forms of industrial or municipal waste equivalent. The vast majority of this is in the form of tailings and other waste rock products, such as waste dumps and spent leach heaps. Furthermore, most mining operations extract one to two commodities of value, representing only a small portion of the material disturbed as part of the operation. However as clean energy technology uptake increases, so does our requirement for a large range of minerals and metals that were not historically of interest, many of which are designated 'critical'. The opportunity exists to make better use of mine waste to augment and diversify global critical mineral supply, reduce or remove large volumes of waste from mining operations and thereby improve environmental outcomes for mine sites during and beyond mine closure. In this desktop study, our goal is to demonstrate the viability of creating a valuable product from every component of a mine's waste rock material. Using the waste composition of a typical Queensland sedimentary-hosted Cu-Pb-Zn deposit as a starting point, a high level flow sheet for zero waste outcomes was designed. Critical metals targeted include HPa, as, Co, Mg, Mn and Si. Many of these are common elemental components of typical rock forming minerals, and are not themselves rare. additional 'strategic' metals that were targeted include Cu and Zn. The goal for all remaining metals, minerals and other products was to propose outcomes that maximise value and minimise harm. By adding a suite of critical and other minerals and metals to traditional commodity production, mine operations are able to diversify their portfolio and may be somewhat protected from the vagaries of individual commodity markets. On demonstration of the technical and commercial viability of the zero-waste mine, the next step for this project is to develop a site-based pilot study, with real-world inputs and outcomes.
