how to separate vanadium from titanium

A novel process featuring pressurized pyrolysis of ammonium chloride-acid leaching-solvent extraction was carried out to separate vanadium, titanium and iron from vanadium-bearing titanomagnetite (VBT). Then vanadium and iron existed in the form of ammonium polyvanadate ((NH4)2V6O16) and ammonium jarosite (NH4Fe3(SO4)2(OH)6) after precipitation from the water phase and the raffinate, while ...

01-09-2019· The separation of titanium (Ti) (IV) in acidic leach solutions of vanadium slag by solvent extraction with ctyl tertiary amine (N235) is proposed. Because the leach solutions contain a lot of vanadium (V) and iron (Fe) impurities, the effects of various conditions on the separation of Ti, V, and Fe were investigated.

03-02-2018· After a water leaching process, 85.61% of the vanadium from the roasting slag was leached, confirming the sodium oxidation of most of the vanadium oxides to water-soluble sodium vanadate during the roasting process. The total recoveries of iron, vanadium, and titanium were 93.67%, 72.68%, and 99.72%, respectively.

The separation and recovery possibilities of vanadium(V) from other associated metal ions, viz magnesium(II), aluminium(III), titanium(IV), chromium(III), manganese(II) and iron(III), which are ...

The method for separating titanium and/or vanadium from pig iron envisages a sufficient quantity of iron oxides for slagging titanium being added to the pig iron in a first stage, the titanium being slagged and the slag separated, and then a sufficient quantitiy of iron oxides for slagging vanadium being added, and the vanadium-enriched slag formed being separated, whereupon the pig iron is ...

01-05-2019· Gas-based reduction roasting magnetic separation process was conducted to separate and recover iron and titanium from oxidized vanadium titano-magnetite (VTM). The effects of reduction temperature, gas composition, reduction time, grinding fineness, and magnetic field intensity on the efficiency of Fe-Ti separation were investigated.

The subsequent separation of scandium and titanium from the scandium-titanium residue is the key to recover these two valuable metals from the red mud. Based on the difference in hydrolysis behavior between titanium and scandium, it is feasible to keep the titanium remaining in the solid phase while gradually leaching the scandium species to the liquid phase through acidity adjustment.
