Magnetic Separation of Phosphorus Enriched Phase from

The authors have found that phosphorus exhibits remarkable segregation in exhausted actual hot-metal pretreatment slag (dephosphorization slag) and it exists as a 3CaO·P 2 O 5 –2CaO·SiO 2 solid solution with the FeO–CaO–SiO 2 matrix. Since their magnetic properties are significantly different it is possible to separate them with the aid of a superconducting strong magnetic field.
