Abstract
⺠Phosphogypsum wastes are proposed to reduce CO2 greenhouse gas emissions. ⺠Phosphogypsum dissolution with NaOH results in Ca(OH)2 precipitation and Na2SO4. ⺠Aqueous carbonation of Ca(OH)2 with CO2 results in the CaCO3 precipitation. ⺠Metals contained in the phosphogypsum are transferred to the final calcite. ⺠Applications of CaCO3 and Na2SiO4 by-products are proposed to improve viability.
