The research program is aimed at developing novel test procedures and models for High Pressure Grinding Rolls (HPGRs) for comminution of metal ores classified by geology and physical properties. The HPGR is an energy efficient technology and there are presently no accepted small scale tests for sizing the technology for large scale operations. The study […]

Narrow-vein steeply dipping deposits are challenging to mine economically because they are poorly oriented for surface mining, and underground mining normally requires development of extensive underground infrastructure before mining the vein. Memorial University is currently collaborating with Anaconda Mining for the development of innovative narrow-vein mining (NVM) technology to mine several of these deposits currently […]

Comme dans toute industrie d’importance, les activités minières engendrent des rejets liquides qui nécessitent une gestion spécifique afin de garantir leur innocuité environnementale. Pour réduire l’impact du déversement de ces effluents miniers dans l’environnement des normes environnementales ont été définies. Malgré les traitements des eaux, les objectifs environnementaux de qualité des effluents peuvent occasionnellement ne […]

Over the past 5 years, Suncor Energy has invested in the Energy Futures Lab, the Engineering Change Lab, the Getting to Maybe social innovation program, the Suncor Energy Foundation Gathering, and most recently, the Turtle Island Institute. All of these initiatives are designed to transform whole systems in rapidly changing environments in partnership with diverse […]

It is fairly common knowledge that we should not drive while drowsy. Yet often in high risk professions, people grow tired throughout the day and begin to make mistakes. How do we know when that person needs a rest? Recent advancements now allow us to read peoples’ brain activity as they go about their day-to-day […]

Throughout much of northern and rural Canada roads are constructed of unpaved gravel aggregate. They are expensive to maintain, environmentally problematic and degrade quickly. We are developing a solution to this problem by using locally derived materials rich in reactive clays. With the addition of catalysts and polymeric agents, we cause the fine clay materials […]

The Decar nickel deposit is located in British Columbia. With more than 2 billion tons of reserves grading 0.2% Ni the deposit represents a significant resources. The nickel occurs in an uncommon mineral awaruite which is an alloy of nickel and iron. Due to its strong ferro-magnetic properties and high density (SG 8.0) it should […]

Offshore Newfoundland is an ice-prone environment which holds valuable natural resources. Better understanding of the ice environment and ice characteristics in this region is essential for safe and economical offshore activities. In this proposed research, we aim to develop advanced models that provide a deeper understanding of some aspects of ice dynamics and deterioration and […]

La région de Baie James au Québec est une zone où l’exploration est en plein essor et présente un potentiel minier florissant notamment dans le secteur de l’or. Afin de faciliter l’exploration il est nécessaire de mieux comprendre l’environnement géologique de la région et le contexte de mise en place des minéralisations. Cette étude en […]

La mine Goldex est une mine souterraine en cours d’exploitation par l’entreprise Agnico Eagle. En 2015, un nouveau projet d’extraction a été développé, la zone Deep 1, dont la production a débuté en juillet 2017. Actuellement, des forages d’exploration sont en cours dans une nouvelle zone, la zone Sud. Le minerai provenant de ces zones […]

This research focuses on dry comminution technologies and specifically on the Vertical Roll Mill. Goldcorp recently announced a new initiative referred to as H2zero with the goal of reducing water usage in their mining operations by 80 to 100%. The study will compare energy usage in comparison to conventional wet ball mill grinding. The study […]

Canadian bitumen has high viscosity compared to conventional crude oils which unable its transportation to upgraders and refineries by pipeline. In order to improve its fluidity, bitumen is submitted to high temperatures that will allow the break of chemical bonds. This process is called visbreaking. Nevertheless, the product is unstable due to the presence of […]
