Un nouveau style de minéralisations porphyrique en or a été découvert le long et au sud de la faille Cadillac en Abitibi à Malartic. On n’en connait pas les extensions possibles. Dans le secteur New Alger, le stagiaire pourra tester la présence ou l’absence de ce style de minéralisations par des levés géologiques et géochimique […]

The Eldorado Gold Corp. has developed a method of treating a hard-to-process ore from a mine in China in order to increase their recovery of gold. While this process has proven to be effective, more research is needed on the exact method in which this technique works on a very small-scale and detailed basis. The […]

This unique research project, undertaken by Master of Northern Governance and Development (MNGD) students, contributes significantly to our understanding of the North. The research focuses on community-based responses to rapid economic, social, and environmental changes and the development of the local capacity to respond. The analysis is collaborative, involving key stakeholders at the community and […]

The Mount Polley tailings impoundment failure released 24 million m3 of mine-influenced water and sediment into the surrounding watershed. The scale of this spill is unprecedented in BC history, and the effects on current and future ecosystems are unknown. Of paramount concern is the containment of toxic metal-containing compounds that threaten aquatic life. My research […]

The exploration phase of the Agnico Eagle Meliadine Mine (AEMM) close to the community of Rankin Inlet, Nunavut overlaps with a study area where our research group has been studying the ecology of Arctic peregrine falcons since 1980. We are now taking advantage of this unique opportunity to combine a long-term, pre-disturbance data set with […]

Le site minier Doyon possède des centaines d’hectares couverts de tonnes de résidus miniers. Vu l’impact majeur des déchets miniers sur l’environnement, le MDDEP oblige, par des lois, la restauration de ces sites. Le Centre Jardin Lac Pelletier (CJLP) et le CTRI ont développé des techniques de restauration de sites miniers en valorisant la MOR […]

The evermore increasing complexity of gold ores is forcing operations to seek alternative gold leaching reagents to the traditional use of cyanidation. At the Barrick Goldstrike mine, the implementation of a non-toxic thiosulfate leaching process is about to become an industrial reality. With modification to the existing infrastructure and leaching circuit, this new process allows […]

Autoclave treatment of refractory sulfide gold ores oxidizes minerals, such as pyrite, containing gold that cannot be recovered through conventional cyanidation. Oxidation liberates the gold by putting iron into solution. At high temperature and pressure, the dissolved iron tends to precipitate. A problematic iron precipitate that may form is basic iron sulfate (BFS). In the […]

The British Columbia Natural Gas Strategic Research Initiative (BC NGSRI) is a strategically targeted collaborative research network designed to tackle some of the most pressing challenges in the natural gas sector. A three-way government-industry-academic partnership connected through student interns will provide applicable tools and knowledge to effectively optimize resource use and mitigate risk throughout natural […]

This Mitacs Accelerate proposal is the second of three-phase project of Adriana’s Goncalves master’s thesis. For this Mitacs-Accelerate renewal proposal, it will be investigated further flotation process targeting recovery of 80-90% considering a previous technical feasibility study conducted on material from a representative sample of ASM tailings from Costa Rica. The tailings belong to a […]

Scandium (Sc) is a rare, but strategic element for many high-tech applications such as next generation fuel cell technologies. Typically, it is required as highly pure (99.99%) Sc2O3. Currently, the global supply of Sc2O3 is very small and concentrated in a few countries. There is currently no production know-how available in Canada. The principal source […]

ln Situ Recovery (ISR) mining is used for about 47% of uranium mining globally. Regulations on restoration of mined aquifers require a return to pre-mining baseline water quality conditions, or conditions where the risk of human exposure is as low as reasonably achievable. Determining the attenuating capacity of down-gradient aquifer solids is key to quantifying […]
