Carbon Sequestration Kinetic and Storage Capacity of Ultramafic Mining Waste

Abstract: Mineral carbonation of ultramafic rocks provides an environmentally safe and permanent solution for CO(2) sequestration. In order to assess the carbonation potential of ultramafic waste material produced by industrial processing, we designed a laboratory-scale method, using a modified eudiometer, to measure continuous CO(2) consumption in samples at atmospheric pressure and near ambient temperature. The eudiometer allows monitoring the CO(2) partial pressure during mineral carbonation reactions. The maximum am… Show more

“…These tailings, which are otherwise a waste product, are a potentially valuable mineral feedstock for carbon mineralization because of their quantity, mineralogical composition, and high reactive surface areas that are generated during ore processing. Although felsic tailings may also act as mineral feedstock for carbonation reactions, ultramafic and mafic mine wastes have been the focus of most studies as these wastes are more reactive (e.g., [18,25]). …”

“…Specifically, numerous studies have explored the use of ultramafic mine wastes as a potentially valuable feedstock for carbon mineralization [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29]. Ultramafic and mafic mines generate vast quantities of mine tailings that offer a readily available, fine-grained feedstock for carbonation.…”
