Abstract

An indirect mineral carbonation of phosphogypsum with NaCl and NH4OH was proposed. The effect of different process conditions on the extracting process of CaSO4·2H2O in phosphogypsum, the carbonation ratio of Ca2+ in the CaSO4·2H2O lixivium, and the crystal phase and morphology of the product during the carbonation process were systematically discussed. NaCl was tried to be reused. Impacts of NaCl recycling number on the carbonation reaction efficiency and the crystal phase of the carbonated products were also studied. The leaching rate of Ca2+ in phosphogypsum was 49.42% under the optimized conditions. The carbonation ratio was 96.31%. The carbonated product composed of pure calcite, or vaterite and calcite was successfully prepared by adjusting the reaction conditions and NaCl cycle number. The performance of the obtained product met the Chinese standard requirements of HG/T 2226–2010. The proposed PG carbonation strategy showed potential prospect of application.
