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 ... -
Hydrogeochemical, Mineralogical and Microbial Processes Occurring in Old Sulfide-Rich Tailings
(University of Waterloo, 2015-09-30)The former Sherritt-Gordon Mine, located in Sherridon Manitoba, processed approximately 7.7 Mt of sulfide ore between 1931 and 1951. The Zn-Cu volcanic massive-sulfide ore body yielded Zn and Cu concentrates with minor ... -
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 ... -
Oxidation characteristics, acid neutralization, secondary minerals, and trace elements associated with pyrrhotite oxidation in historical waste rock
(University of Waterloo, 2022-07-27)The Detour Lake Mine is an open pit, greenstone-hosted gold mine in Ontario, Canada. Mining produced waste-rock piles that were constructed from 1983 – 1999. Redevelopment and expansion of the open pit required the excavation ...
