Mining tailings are being upgraded – in order to capture carbon dioxide

The industrial green transition causes a larger-than-ever demand of metals. Now researchers at Luleå University of Technology will identify for the first time the potential of typical Swedish mine tailings, to be utilized and beneficial for the climate. In this project, researchers will investigate the potential of typical Swedish mine tailings to capture and store (CCS) by using tailings from Boliden Mineral, LKAB, and Copperstone Resources. Two different CO2 sources will be used, industrial emissions and direct air capture (DAC).
