Abstract: The effect of CaCO 3, Na 2 CO 3, and CaF 2 on the reduction roasting and magnetic separation of high-phosphorus iron ore containing phosphorus in the form of Fe 3 PO 7 and apatite was investigated. The results revealed that Na 2 CO 3 had the most significant effect on iron recovery and dephosphorization, followed by CaCO 3, the effect of CaF 2 was negligible

Steel slag can also be produced by smelting iron ore in a basic oxygen furnace. According to methods for cooling molten steel slag, steel slag is classified into five types: natural air-cooling steel slag, water-spray steel slag, water-quenching steel slag, air-quenching steel slag, and shallow box chilling steel slag [47,48]
