Project Objectives

This project will advance new technologies for mineralizing CO2 captured from air and flue gas within the mineral waste stream of mine operations to sequester CO2 as a stable and benign carbonate and achieve a net reduction in the greenhouse gas (GHG) emissions of mine operations.

The project also will test CO2 delivery and tailings management practices that have proved successful in benchtop-scale experiments at a larger scale at field demonstrations at two Canadian mine sites. The field trials will be the first on-site testing of accelerated CCUS pilots in hard-rock mine tailings globally.

Expected Results

This technology will increase the understanding of carbon mineralization (especially in mine tailings), and carbon mineralization will give the Canadian minerals sector a competitive edge in reducing GHG emissions with it’s potential for high capture efficiency.

There is a strong potential for implementation at other sites in Canada's North, going forward. This technology may also be applicable in diamond and nickel mines.

Anticipated Environmental Benefits: This project will build towards mine operations with zero or net-negative GHG emissions.
