Vanadium Extraction
Titanomagnetite deposits containing 0.5-1.5% V₂O₅ processed to extract vanadium.
Salt Roasting
Concentrate mixed with NaCl roasted at 800-850°C converts vanadium oxides to water-soluble sodium vanadate.
V₂O₅ Production
Purified vanadium solution precipitated as ammonium polyvanadate, calcined to produce V₂O₅ (98-99%) for steel alloying.
