Geochemical and mineralogical aspects of sulfide mine tailings
Tailings generated during processing of sulfide ores represent a substantial risk to water resources. The oxidation of sulfide minerals within tailings deposits can generate low-quality water containing elevated concentrations ...
Vanadium geochemistry of oil sands fluid petroleum coke
(American Chemical Society, 2017-02-09)
Vanadium has previously been linked to elevated toxicity of leachates derived from oil sands petroleum coke. However, geochemical controls on V mobility within coke deposits remain poorly constrained. Detailed examinations ...
The persistence of brines in sedimentary basins
(American Geophysical Union, 2018-05-08)
Brines are commonly found at depth in sedimentary basins. Many of these brines are known to be connate waters that have persisted since the early Paleozoic Era. Yet questions remain about their distribution and mechanisms ...
Tracing molybdenum attenuation in mining environments using molybdenum stable isotopes
(American Chemical Society, 2019-04-18)
Molybdenum contamination is a concern in mining regions worldwide. Better understanding of processes controlling Mo mobility in mine wastes is critical for assessing potential impacts and developing water-quality management ...
