Effectiveness of Organic Carbon Cover Systems on Sulfide-rich Tailings
(University of Waterloo, 2021-09-27)Acid mine drainage (AMD) occurs when sulfide minerals oxidize; generating low pH water and the release of dissolved metals. This phenomena is of primary concern in the mining industry, where the future loading of dissolved ... -
Geochemical and microbiological characterization of effluent and pore water from low-sulfide content waste rock
(University of Waterloo, 2013-04-22)Laboratory and field studies were completed to characterize the geochemistry and microbiology of drainage emanating from low-S content waste-rock test piles at the Diavik Diamond Mine (Diavik) from 2007 through 2010. The ... -
Geochemical and Microbiological Characterization of the Historic Waste Rock Piles at the Detour Lake Gold Mine
(University of Waterloo, 2016-09-16)Four of the historic waste rock stockpiles (WRS #1-#4) at the Detour Lake mine site were studied to determine the potential for generation of acid rock drainage (ARD). The stockpiles were constructed during the original ... -
Hydrogeochemistry and Trace Element Mobility in an Acidic High-Sulfide Tailings Impoundment After 40 Years of Oxidation
(University of Waterloo, 2024-01-25)Abandoned mine sites can create a legacy environmental contamination issue when the generation of acid mine drainage is allowed to continue with insufficient or absent remediation measures. The South Bay mine, a former ... -
An Investigation of Heterogeneity and the Impact of Acidic Regions on Bulk Effluent from a Deconstructed Low Sulfide Waste-Rock Pile
(University of Waterloo, 2017-05-15)Waste rock is a potential source of low quality drainage resulting from oxidation of naturally occurring sulfide minerals. Sulfide oxidation may result in the generation of effluent with elevated concentrations of SO4 and ...
