Frequently Asked Questions

Q: Where Does Vanadium Come From?

Vanadium is a naturally occurring chemical element found in various minerals, ores, and fossil fuels.

Vanadiferous titanomagnetite is the most significant source of vanadium. It is often found in titanomagnetite ores—iron ore deposits containing titanium and vanadium. These ores are mined in countries such as South Africa, Russia, China, and Brazil.

Vanadium can be extracted as a byproduct during the processing of uranium ores. Many uranium deposits contain significant concentrations of vanadium, and its extraction can be economically viable alongside uranium mining.

Some phosphate rocks contain substantial amounts of vanadium. In regions where phosphate mining is prevalent, these rocks can serve as another valuable source of vanadium. 

Vanadium can also be found in coal deposits and oil sands. During the combustion or processing of coal and oil sands, vanadium may be released and concentrated in byproducts such as fly ash or petroleum residues.

Once extracted from its various sources, vanadium is processed and refined using chemical and metallurgical techniques to obtain pure vanadium metal or vanadium compounds for industrial use.

Q: How Is Vanadium Used?

Vanadium has many uses due to its versatility and unique properties. It plays a role in technological advancements, infrastructure, energy storage, and environmental sustainability.

One of the primary uses of vanadium is as an alloying element in steel production. Vanadium steel, often referred to as high-strength low-alloy (HSLA) steel, exhibits superior strength, toughness, and wear resistance compared to pure steel or other alloys. This material is used in applications such as the creation of structural components for buildings and bridges, as well as pipelines, automotive parts, and tooling. Vanadium steel is also often used to produce high-end cutlery.

Vanadium alloys are used in aerospace and defense applications such as aircraft components, missile structures, and armored vehicles due to their high strength-to-weight ratio and their resistance to fatigue. 

Vanadium compounds serve as catalysts in various chemical reactions. For example, vanadium pentoxide is used in the production of sulfuric acid, one of the most widely used industrial chemicals. Vanadium catalysts also play a role in the oxidation of organic compounds and in certain petrochemical processes.

Vanadium-based redox flow batteries (VRFBs) are emerging as a promising technology for grid-scale energy storage. VRFBs store energy in the form of vanadium ions dissolved in an electrolyte solution, offering key advantages such as scalability, a long cycle life, and high efficiency. They are used for renewable energy integration, load leveling, and backup power applications.

Vanadium compounds are also used in electronics manufacturing, particularly in the production of certain types of electronic components and semiconductor devices. For example, vanadium oxide thin films exhibit properties suitable for applications in sensors, optoelectronics, and smart glass coatings.

Vanadium-based catalysts are employed in catalytic converters used in automobiles to reduce harmful emissions from exhaust gases by converting pollutants such as nitrogen oxides (NOx) and carbon monoxide (CO) into less harmful substances.

Finally, vanadium compounds have shown potential in medical research and pharmaceutical applications. They are currently being investigated for their insulin-mimetic properties and potential therapeutic effects in the fight against diseases such as diabetes and cancer.
