Optimization of a Cover Design for Acid Rock Drainage Prevention in a Permafrost Environment
DownloadFall 2021
The extraction of sulfide-bearing waste rock can contribute to the generation of acid rock drainage (ARD). ARD is the effluent generated due to the oxidation of sulfide minerals which can be toxic to the receiving environment. Waste rock material which contains potentially acid-generating (PAG)...
