    In this study, we adopted a selective leaching–chemical precipitation process to recover P from steelmaking slag. The effects of the acid, pH, and valence of Fe in slag on the leaching characteristics of P were first investigated. Chemical precipitation was then adopted to extract P from the leachate. The characteristics of the final product were evaluated. The results indicate that the P
