Effect of Na2O Addition on Phosphorus Dissolution from .

Abstract. Slag with high P 2 O 5 content generated during the use of high-P iron ores is an important potential source of phosphate. Because the P-rich 2CaO·SiO 2 –3CaO·P 2 O 5 solid solution in the slag was preferentially dissolved compared with other phases in aqueous solutions, selective leaching of P from slag with high P 2 O 5 content was applied to recover soluble P in this study.
