- Diavik Waste Rock Project: acid rock drainage in an Arctic climate
How does the freeze-thaw cycle of the semi-arid Arctic and the presence of permafrost influence the generation of acid rock drainage, metal release, and the microbial catalysis of sulfide minerals during oxidation.
- Metal Nanoparticles and Sulfidic Sediments
Investigating the formation, stability, and behavior of metal nanoparticles derived from the oxidative dissolution of sulfide minerals contained in mine waste sediments.
