1. Introduction. China is rich in titanium resources, most of which are stored in Sichuan province in the form of vanadium‑titanium magnetite ore (Du, 1996).Generally, vanadium‑titanium magnetite concentrate including Fe of 30%, TiO 2 of 10%, and V 2 O 5 of 0.3% is smelted by using blast furnaces. Metal iron is separated from titanium by Vanadium titanomagnetite is an important source of vanadium and titanium throughout the whole world. During enrichment about 82 wt.% of vanadium, 54 wt.% titanium, and 75 wt.% of iron are transferred into iron concentrate [1, 2].Currently vanadium titanomagnetite concentrate (VTMC) is used as a charge in blast furnace (BF) Investigation of Vanadium Titanomagnetite Concentrate

Extraction of vanadium from vanadium slag by high pressure
During the high pressure oxidative acid leaching process, the fayalite and spinel phases are gradually decomposed by sulfuric acid, causing the release of vanadium and iron in the solution. Meanwhile, unreacted silicon and titanium are enriched in the leach residues.
