By invitation only
Annual workshop of the CRC TiME project: Improved Prediction, Remediation and Closure of Acid and Neutral Metalliferous Drainage (AMD/NMD) Sites by Examination of Mine Waste Behaviour at the Meso-scale
Annual workshop of the CRC TiME project: Improved Prediction, Remediation and Closure of Acid and Neutral Metalliferous Drainage (AMD/NMD) Sites by Examination of Mine Waste Behaviour at the Meso-scale
This 5-year project is funded through CRCTiME and is conducted by a collaborative research team based at Flinders University and the Sustainable Minerals Institute.
The project involves the University of Windsor, eight mining and METS companies, Minerals Research Institute of Western Australia (MRIWA), the Department of Agriculture, Water and the Environment (DAWE), International Network for Acid Prevention (INAP), and Blue Minerals Consultancy.
