Abstract: A procedure for producing high-purity CaCO3 by yellow phosphorus slag carbonation was proposed. The impacts of technological parameters on acid-leaching and carbonation results were discussed. The calcium leaching rate was 99.8%, while the acid-leaching product was amorphous silicon dioxide with granular morphology and some pores in the surface. The carbonation ratio was 98.10%: 1 t of yellow phosphorus slag can be used to produce 881 kg of CaCO3 and sequester 388 kg of CO2 under the optimized conditions. The CaCO3 satisfied the Chinese recommended industrial standard of HG/T 2226-2010. The products with a single calcite or vaterite structure, or binary and trinary mixed structure of calcite, vaterite and aragonite were all successfully prepared. A preliminary economic evaluation predicted that our yellow phosphorus slag carbonation procedure held a promising application for CO2 sequestration.
