• The effects of the dynamic oxidation on the physical chemical characteristics of the Ti-bearing blast furnace slag, on the selective enrichment, precipitation and growth of the Ti component and the drop of metallic Fe from the slag have been investigated. Air was blown into the molten slag as oxygen resource through a lance during the dynamic oxidation process. It was found that the TiC, TiN, (Ti2O3), Fe and (FeO) in the slag were oxidized, and the temperature of slag increased and the viscosity of slag decreased. These were not only in favour of the selective enrichment of the Ti component into the perovskite phase, but also in favour of the precipitation and growth of the perovskite phase, meanwhile promoted the coalescence, growth and drop of the metallic Fe droplets in the molten slag under an air agitation condition.
