Vanadium can be recovered from titaniferous magnetite ore by either of two processes: (1) precipitating a vanadium salt from a leach of ore roasted with salt, or (2) precipitation from a leach of salt-roasted vanadium-rich slag obtained by smelting the ore to make a vanadium …

Vanadium Resources in Titaniferous Magnetite Deposits

A magnetically recyclable vanadium(V) catalyst was synthesized by covalent anchoring of VO(salen)Cl on silica-coated Fe3O4 nanoparticles. This straightforward preparation yields magnetically separable [email protected]@VO(salen) nanoparticles with high vanadium loading. These nanoparticles were efficient catalysts for selective oxidation of sulfides to corresponding sulfoxides with urea hydrogen ...

Co-recovery of iron, chromium, and vanadium from vanadium ...

Vanadium is a chemical element with the symbol V and atomic number 23. It is a hard, silvery-grey, malleable transition metal.The elemental metal is rarely found in nature, but once isolated artificially, the formation of an oxide layer (passivation) somewhat stabilizes the free metal against further oxidation.. Andrés Manuel del Río discovered compounds of vanadium in 1801 in Mexico by ...
