Solutions that enable the cost-effective recovery of secondary minerals from mining waste can unlock valuable critical and strategic mineral resources and may offset the costs of mine rehabilitation activities.
Recognising the potential value of these assets, Geoscience Australia recently launched an online Atlas of Mine Waste to provide information about mine tailings, waste rock, and other mining waste stockpiles in Australia.56 Cost-effective solutions that support secondary mineral extraction from waste streams such as tailings, wastewater, and waste rock stockpiles present an opportunity to improve closure outcomes. Consultations have noted that economic recovery opportunities are present in legacy sites where less efficient extractive processes have left high concentrations of target minerals in waste. |
