    The indirect vanadium extraction process is widely used in the industry [2,4,5] in combination with the blast furnace process and could greatly improve the production efficiency [6,7,8]. In recent years, a large amount of vanadium–titanium

  • Efficient Extraction of Vanadium from Vanadium–Titanium

    2018-1-17 · vanadium–titanium magnetite is another major raw material from which to extract vanadium. China’s vanadium–titanium magnetite reserves are huge—up to 9.83 billion tons that reach mineable grade—and are therefore of high utilization value [2,3]. Generally, the indirect vanadium extraction process takes place after iron-making; vanadium

  • Extraction of titanium, vanadium and iron from

    1995-1-1 · Over 98% of the titanium and vanadium reported to the slag phase. The slag was roasted with soda ash at 950°C and then leached with hot water at 80°C to recover vanadium. The leach residue was further treated with hydrochloric acid at 105°C in order to upgrade TiO 2 content by removing mainly iron, magnesium and aluminum.

  • The extraction of vanadium from titanomagnetites

    2020-1-15 · Vanadium can also be produced from vanadiferous sandstone, shale and vanadate deposits, though these are of lesser industrial importance compared to titanomagnetites. Vanadium is usually extracted from ores, concentrates and slags by roasting with sodium carbonate or another sodium salt to convert vanadium into water soluble sodium vanadates.

  • Efficient separation of vanadium, titanium, and iron

    2021-1-15 · The extraction rate of vanadium, iron and titanium were measured to be 91.8%, 88.3%, and 0.96%, respectively, which reveal that a part of vanadium and iron were trapped in the phase of titanium and silicon, and thus it was difficult to dissolve in the aqueous solution . In this experiment, 61.7 g/L HCl leaching could fully dissolve vanadium and iron from the roasted
