HPGR Model Development for Different Ore Classes

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 […]

Research for Innovative Mining Methods

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 […]

Évaluation de la toxicité d’effluents miniers sur la daphnie

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 […]

Clay Binding of Gravel Roads

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 […]

Development of an advanced ice dynamics and deterioration model and a DEM flexural ice failure model

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 […]

Impact de différents collecteurs sur la flottation de la pyrite : application aux deux zones minéralisées de la mine Goldex

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 […]

Investigation of a Vertical Roller Mill for Metal Ore Processing

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 […]
