  "abstract": "Indirect CO 2 mineralization of Fe-rich serpentinite tailings was evaluated by connecting ammonium sulfate-assisted activation, Mg-Fe separation, carbonate precipitation and salt crystallization across laboratory, engineering and pilot scales. Under the selected activation conditions, 52.08% of the feed Mg was mobilized, and most dissolved Mg was preserved during NH 3 -assisted purification. Hydrated Mg-carbonate formation was supported by XRD and SEM-EDS, and an ammonium sulfate-containing crystalline stream was recovered downstream. Approximately 92% of the mean laboratory Mg-leaching performance was retained on the 1.6 kg/h engineering line. An independent 125 kg/batch pilot campaign was operated for 72 h using cleaned boiler flue gas. Constraints in kiln operation, solids separation and crystallization were identified during scale transfer. Unit-basis screening calculations were used to examine the sensitivity to evaporation demand and fresh-reagent supply. Cross-scale process connectivity was demonstrated, while Mg-based capacities were treated as conditional inventory estimates. Actual carbonate-carbon retention, repeated reagent reuse and net climate benefit were not established by the available measurements.",
