Dephosphorization slag contains a large amount of valuable components such as CaO, SiO2, FeO, P2O5, etc., and has the potential to be used as soil amendment and fertilizer. To promote utilization of dephosphorization slag in agriculture, it is necessary to understand its dissolution behavior in the organic acid solution. The influence of pH and organic acid type on the dissolution ratios of various valuable elements from dephosphorization slag was investigated. The results show that the main mineral phases in the dephosphorization slag are RO phase, CaFeSiO4 matrix phase, and C2S-C3P solid solution. Ca and Si elements in the slag are mainly distributed in the C2S-C3P solid solution and CaFeSiO4 matrix phase, while the P element is enriched in the C2S-C3P solid solution. Fe element is mainly distributed in the RO phase. As the pH value decreased, the dissolution of slag is significantly promoted, and most of the dephosphorization slag can be dissolved in the citric acid solution. At pH=5, the dissolution ratios of Ca, Si, Mg elements are about 90%, and the P dissolution ratio is 68.84%, achieving the dissolution of valuable elements.
