The RIME’s research program focuses on several major themes related to mining and the environment. Our program currently includes several research chairs and a dozen major research projects. In addition to the financial support provided by our industrial partners, funding for research is provided by both provincial and federal funding agencies from Quebec and Canada.

Research Themes

Mine site reclamation

Circular economy applied to mines : Valorization and integrated management of wastes

Geotechnical and geoenvironmental stability of mine waste storage facilities

Water quality prediction

Treatment and management of mine waters

Transport of contaminants in the environment

Influence of climatic conditions

Knowledge sharing and exchanges with local communities

Research Chairs

NSERC-UQAT industrial chair on mine reclamation

Chairholder : Bruno Bussière

The long-term goal of this Research Chair is to develop reclamation strategies that limit the environmental impacts and risks of mining. This industrial chair has enabled the development of innovative new technologies, as well as the improvement of existing technologies, for the reclamation of tailings storage facilities and waste rock piles.
