Abstract

The Fe-bearing phase and P-bearing phase were successfully separated from a steelmaking slag by the super gravity and the separated efficiency was improved with increasing the separated time. The P-bearing phase precipitating at 1663 K was intercepted by the filter, while most residual melt went through the filter into the lower crucible to form calcium iron and aluminum and solid solution of iron, magnesium and manganese (RO phase) after centrifugal separation. Under the condition of gravity coefficient G=600 g, T=1663 K and t=15 minutes, the mass fraction of P2O5 in the P-bearing slag increased from 2.49 wt% before separation to 3.56 wt% and that of FetO in the Fe-bearing slag from 23.99 wt% to 38.67 wt%. The recovery ratio of P2O5 and FetO accounted for 82.2% and 68.5%, respectively.
