Abstract: <p>Mineral feedstocks, including alkaline mine wastes, can sequester CO2 as a dissolved phase (e.g., HCO3-) or a solid carbonate via enhanced rock weathering (ERW). For this thesis, the release of easily accessible Ca and Mg from non-carbonate sources was determined for kimberlite residues from several diamond mines and commonly proposed ERW rock types, including wollastonite and olivine.… more

Abstract: <p>Mafic and ultramafic mine wastes have the potential to sequester atmospheric carbon dioxide (CO2) through enhanced weathering and CO2 mineralization. In this study, kimberlite residues from South African diamond mines were investigated to understand how weathering of these wastes leads to the formation of secondary carbonate minerals, a stable sink for CO2. Residues from Venetia Diamond… more
