Les résidus de bauxite sont des déchets générés en grande quantité lors de la production d’aluminium. Ils sont souvent déposés dans des bassins de sédimentation engendrant ainsi de sérieux impacts environnementaux et économiques. L’utilisation de ces déchets pas ou peu valorisés pour l’élaboration des produits à haute valeur ajoutée est encouragé par l’entreprise Rio Tinto […]

Open pit slope engineering involves balancing economic requirements and risk, where an optimum pit slope design seeks to safely increase the slope angles to minimize the mining of waste, while maximizing ore recovery. In turn, this can reduce the carbon footprint of the operation, as less excavation is required. An optimum slope design must satisfy […]

Mining-induced stress in the area around tunnel openings represents a major design consideration in potash mines. In the past, induced stress has been monitored using an array of techniques derived from the hard rock mining industry, one of the key assumptions being linear-elastic deformation behaviour of the rock. When using these methods in a soft […]

Naphthenic acids (NAs) represent the primary source of acute toxicity in oil sands process affected water. Due to the seepage potential of NAs from oil sands tailings ponds into the surrounding surface water and groundwater, environmental monitoring of NAs in water samples from tailing ponds, surrounding groundwater and surface water, and groundwater wells became a […]

The primary objective of this project is to provide Canadian petroleum companies with a set of reliable data derived from experiments conducted on reservoir-on-the-chip platforms that facilitate the visualization of pore-scale interactions between solvent and heavy oil during the CO2-based CSI process in the presence of complex wormhole systems in post-CHOPS reservoirs. The reservoir-on-the-chip is […]

Vegetation in the Lower Columbia Valley in the West Kootenays of BC has been affected by historical emissions from the smelter in Trail, BC. Following logging of the valley for fuel and building materials, metal and SO2 emissions impaired forest regeneration on low valley slopes. A hardy tree species in the legume family native to […]

The intern will determine which factors determine the distribution of gold at the Ulu gold project, in NW Nunavut Canada. This will be accomplished by geologic mapping and examination of drill core at the Ulu site during two summer field seasons. Samples and data collected in the field will be returned to Laurentian University and […]

Fluoro-polymer powder materials have been spotlighted for the use of robust outer surface morphology applications and artistic pattern creation for the outside window in global construction market. However, this anti-sticking art pattern generation on metallic plates like aluminum plates are very challenging compared with the printing on the glass window. So, it’s been a long […]

Dans ce projet, le potentiel d’utilisation de l’essai de résonance par impacts pour faire du contrôle qualité en usine sur les enrobés bitumineux sera évalué. Cet essai est un essai non destructif, économique et simple à réaliser et il pourrait permettre de vérifier à la fois les propriétés volumétriques et les performances des mélanges formulés […]

Like many of the world’s largest mining companies, Newmont is voluntarily targeting net-zero carbon emissions by 2050. Recent research on technical feasibility of mining operation decarbonization has shown that mining companies may be able to achieve up to 70% carbon emissions reductions through internal initiatives, but may require options to capture and store carbon (either […]

Marine icing problems pose significant risk to both marine vessel stability and human safety during harsh weather operations. The project will address a need for better physical understanding of marine icing phenomena and the development of appropriate sensors for detecting marine icing conditions. Current technologies have proven inadequate for marine conditions due to the complex […]

This project is focused on understanding the relationships between copper, gold, and other critical metals in central Newfoundland and their relationships of ore forming fluids to magmatism, faulting and ancient volcanic activity. The work will involve three MSc-level interns that will undertake fieldwork, laboratory work and computer modeling (i.e., machine learning) while being embedded with […]
