Assessment of the potential carbon footprint of engineered processes for the mineral carbonation of PGM tailings [PDF]

International Journal of Greenhouse Gas Control, 2018
Abstract The engineered sequestration of carbon dioxide (CO2) emissions through mineral carbonation typically requires energy intensive conditions and chemical reagents to accelerate the naturally slow reaction processes. In order to be an effective carbon dioxide mitigation strategy, engineered mineral carbonation processes have to result in a net ...
