Abstract

Super gravity technology was used to separate the phosphorus- and iron-enriched phase from CaO-SiO2-FeO-MgO-P2O5 melt. The microstructure and X-ray diffraction showed that the P-enriched phase was intercepted by the filter screen, while the residual slag mainly composed of Fe-enriched phase that went through the filter. The recovery ratio of P2O5 in the P-enriched slag was up to 76.67 pct, and that of FeO in the Fe-enriched slag was up to 85.02 pct.
