De Beers’ carbon-capture research at the Gahcho Kué mine in Canada has received a C$675,000 grant from Natural Resources Canada’s Clean Growth Program.
De Beers Group CEO Bruce Cleaver said: “This award will help us accelerate this innovative work that could fundamentally change the carbon footprint of not only the diamond industry, but the mining sector more broadly.”
The research project is a three-year study not only in Canada, but also mines in Botswana and Venetia in South Africa with four institutions: The University of British Columbia, Trent University, University of Alberta and INRS in Quebec. Research activities involve injecting carbon dioxide into processed kimberlite rock in order to accelerate the naturally occurring process of mineral carbonation, whereby processed mine rock (material left after the recovery of diamond from source rock, kimberlite) sequesters the carbon dioxide as a stable and benign carbonate mineral.
