The combined process of treating alkaline solid wastes and obtaining CO2 sequestration has recently garnered significant attention. However, studies focusing on low chemical consumption alongside high-purity CaCO3 production are still limited. Herein, a leaching/regeneration-mineralization for mineralization to concurrently produce was proposed. First, selective leaching Ca from municipal waste incineration fly ash (MSWI FA) conducted with the assistance protonated tripropylamine (TPA) at pH = 10.5, concentration 23,500 mg/L. Concurrently, TPA regenerated subsequent mineralization, completing kinetics within 30 min. Temperature had no effect efficiency or product purity. As temperature increased, crystal form transitioned vaterite pure calcite. amount added significantly influenced performance, exceeding stoichiometric ratio allowed nearly 100% promoted transformation product's toward vaterite. Based experimental results characterization, potential proton transfer-based mechanism Under optimal conditions, reached 77.5 g/kgFA, yielding 176 g/kgFA CaCO3. This work offers promising option disposal, sequestration, in reagent-saving manner.
