Abstract Inspired by the growing need for carbon mitigation strategies, this work investigates mechanochemical activation of argon oxygen decarburization (AOD) slag CO 2 sequestration. It explores three process modes: concurrent, sequential, and staged planetary ball milling carbonation. Results showed carbonation uptake reached 70 % theoretical maximum with (0.39 g /g AOD slag) versus 0.17 without milling. The concurrent resulted in fastest rate uptake. Particle agglomeration was confirmed via particle size analysis electron microscopy, non‐reactive mineral phases were identified through quantitative X‐ray diffraction, explaining incomplete conversion.

According to physical property tests of lead-containing slag, the volatilisation behaviour lead slag will have adverse impacts on test accuracy and further affect control chemical reactions, solidification removal inclusions during smelting. To analyse characteristics in this paper, four kinds slags from direct reduction smelting with different PbO ZnO content are taken. thermogravimetry, ISP-TOF were used. Additionally, changes volatiles composition phases analysed XRD ICPS, reaction mechanism was discussed. The results indicated that can a big weight loss about higher content. increases increases. volatile corresponding above 900 °C is mainly less ZnO. temperature is, stronger is. With increase keeping time, most be evaporated leaves little residual slag. This has great effect physico-chemical measurement content, especially kept at high for long time. Because trend condense decrease, mass spectrometer limited by condensation volatiles, i.e., PbO, so on, connection pipeline. device should modified use.
