conducted and successful separation of the molten iron from the titanium slag is obtained. The obtained vanadium-containing molten iron contains 0.681% V and 0.267% Ti, and the obtained titanium slag contains... separation between titanium slag and molten iron. In the Highveld Steel & Vanadium in South Africa, silica and dolomite have been added to dilute titania and mitigate the titanium oxides reduction [13,14......
to produce titanium slag for following titanium extraction [5-10]. In the DR-EF smelting process, vanadium oxides and iron oxides are reduced to molten iron, while titanium oxides are enriched in slag. Vanadium-bearing molten iron is oxidized to produce semisteel and vanadium slag; then vanadium is extracted from the vanadium slag by hydrometallurgy methods [1-4,11,12]. Thus, reduction and distribution......
