Data from high-temperature and high-pressure carbon dioxide sequestration experiments limited to 24 hours, performed on Platinum Group Metals mine tailings from the South African Bushveld Igneous Complex.

ABSTRACT: Mine tailings derived from mafic-ultramafic rock formations may offer promising potential for mineral carbon dioxide (CO₂) sequestration. This dataset evaluates the suitability of South African tailings, produced during Platinum Group Metals (PGM) extraction at the Two Rivers mine, for CO₂ mineralisation under supercritical conditions in a batch reactor. These tailings are typically enriched in oxides such as MgO (12 %), Fe₂O₃ (22 %), and CaO (2 %), which can provide the necessary alkalinity for carbonate formation. They also contain significant amounts of Al₂O₃ (11 %), SiO₂ (18 %), and Cr₂O₃ (34 %), which may influence reaction pathways. Reactivity with CO₂ was investigated under
