| Research Abstract |
The purpose of this study is to reduce the amount of steelmaking slag, especially dephosphorization slag, and to recover valuable phosphorus from the slag. When discharged, the dephosphorization slag exists as phosphorous-enriched solid phases together with matrix liquid phases containing FeO. Because of these characteristics, centrifugation experiments of molten dephosphorization slag were carried out using a centrifugal separator combined with an electric furnace. Consequently, most of the phosphorous-enriched solid phases accumulated in the upper layer of the obtained low-basicity slag.
