Mobilization of Metal(oid) Oxyanions through Circumneutral Mine Waste-Rock Drainage. [PDF]
ACS Omega, 2019 Most studies on the weathering of mine waste rock focus on the generation of acidic drainage with high metal concentrations, whereas metal(loid) release under neutral-rock drainage (NRD) conditions has received limited attention.

Applied Geochemistry, 2020 Abstract Sustained oxidation of sulfide minerals in waste rock generates acid mine drainage for time frames of hundreds to thousands of years. Management to minimize long-term degradation of water supplies and ecosystem health requires a thorough understanding of geochemical processes occurring within the waste rock.
