Seepage of wastewater on mine sites presents significant environmental and engineering risks, particularly in acidic and metalliferous drainage, and the potential for dam failure. Tailings Storage Facilities (TSFs) are a crucial infrastructure asset in the management of mine wastes internationally. TSFs receive a combination of mineral and wastewater products after the extraction of economic minerals (e.g. gold, copper, zinc, etc.) in the form of a slurry that requires careful management. Removing processing waters and returning it back to the industrial process reduces the water demand from a project and minimizes the risk of seepage through the storage of "dry" tailings. For this project, you will review and investigate dry-stacking methods and technologies for possible implementation at a mine site in the northwest Qld region. Stage 1 involves a desktop/GIS/laboratory-based literature review and investigation into the suitability of dry-stack tailings from an environmental risk perspective for a mine site considering using dry tailings to reduce its environmental and engineering risk.
