Vanadium pentoxide is naturally occurring, and it is the most recovered form of vanadium that is found in about 80 different mineral ores. It is present in coal, crude oil, and residual fuel oil. It is present in coal, crude oil, and residual fuel oil.
Vanadium pentoxide dust has given rise to an illness resembling asthmatic bronchitis. Pulmonary fibrosis has occurred in ers exposed to dusts of tungsten and titanium carbides. Chronic asthma can occur after long-term inhalation of chromate dust.
Vanadium pentoxide, Vanadium compounds. Vanadium pentoxide is used in different, industrial processes as catalyst: In the contact process it serves for the oxidation of SO 2 to SO 3 with oxygen at 440°C. Besides it is used in the oxidation of ethanol to ethanale and in the production of phthalic anydride, polyamide, oxalic acid and further products.
Signs and Symptoms of Acute Vanadium Pentoxide Exposure: Acute exposure to vanadium pentoxide may result in pulmonary irritation, bronchospasm, hemoptysis (coughing up of blood), pulmonary edema, emphysema, and pneumonia.
Hazard statement(s) H302 + H332 Harmful if swallowed or if inhaled H318 Causes serious eye damage. H335 May cause respiratory irritation. H341 Suspected of causing genetic defects.

1. Introduction. For several decades, vanadium was considered a low-toxicity essential trace element with antidiabetic and anticarcinogenic properties [1, 2].However, in 2006, the International Association for Research on Cancer (IARC) classified vanadium pentoxide (V 2 O 5) as a Group 2B substance (possibly carcinogenic to humans) based on results in experimental animals .

Abstract. It has been found that vanadium pentoxide in fuel oil ashes reacts with ceramic materials. Sodium aluminate, ß-aluminate, spinel and synthetic spinel have been heated at 650° and 800°C with vanadium pentoxide (melting point 670° to 680°).
Carnotite is the most important mineral for vanadium extraction. Vanadium is also found in some petroleums and bitumens. The most widely used compounds are: vanadium dioxide (VO 2), vanadium tri oxide (V 2 O 3), vanadium pentoxide (V 2 O 5), sodium metavanadate (NaVO 3), vanadium tetrachloride (VC1 4) and vanadium sulfide (VS).
The fundamental understanding of vanadium hydrometallurgy was developed in three phases: vanadium (V) leaching, vanadium (III) oxidative leaching, and solvent extraction of vanadium (V&IV). In the first section, V₂O₅ leaching was studied in three steps. First, vanadium leaching and solubility of VO₂⁺ at different pH’s and temperatures were investigated in sulfuric acid. Secondly, the
