Vanadium titanomagnetite (VTM) is a valuable multi-element symbiotic ore mainly composed of iron, vanadium, and titanium, as well as small amounts of chromium, nickel and cobalt [1,2,3].The …
This deposit is divided into dense and disseminated ores. The main minerals are titanium magnetite, ilmenite, and small amounts of rutile, and pyrite containing cobalt and nickel. Vanadium occurs in magnetite as an isomorphism, where the crystals contain both magnetite and ilmenite, in which magnetite is separated into a solid solution.
In the conventional separation process for vanadium-titanium magnetite, titanium magnetite concentrate (containing vanadium minerals) with an Fe grade of 55.05% is obtained by …
the extractions of vanadium and titanium are inadequate. After mineral processing, about 53% TiO 2 and 61.62% V 2O 5 in the vanadium-titanium magnetite go into the iron concentrate, which transfer into the vanadium-bearing hot metal and the titanium-bearing blast furnace slag with 20–25% TiO 2 that is used to extract titanium material.8) And ...
