8-10% of metal vanadium is used in the form of titanium-aluminum-vanadium alloys for aircraft engines, aerospace cabin frameworks, missiles, steam turbine blades, rocket engine shells, etc. Vanadium can be used as a stabilizer and strengthening agent in titanium alloys, which makes titanium alloys have good ductility and plasticity.In addition, vanadium alloys are also used in magnetic materials, cemented carbide, superconducting materials, and nuclear reactor materials.
The Uses of Vanadium in the Chemical Industry
In the chemical industry, vanadium is mainly used as a catalyst for the manufacture of sulfuric acid and vulcanized rubber. It is also used to suppress the production of nitrous oxide in power plants.Other chemical vanadium products are mainly used for catalysts, ceramic colorants, developers, desiccants, etc.

4 Interesting Facts about Vanadium
The Presence of Vanadium in Nature
In nature, vanadium mainly forms symbiotic ore with other minerals. There are more than 70 kinds of vanadium-bearing minerals discovered at present, but the main vanadium-bearing minerals are the following three types: vanadium-titanium magnetite, potassium-vanadium-uranium ore, and petroleum-associated minerals. 98% of the proven reserves of vanadium resources are stored in vanadium-titanium magnetite, and the V2O5 content can reach 1.8%.
Global Vanadium Production
According to the data released by USGS in 2015, the total output of global vanadium mines in 2015 was 78,000 tons, a year-on-year decline of 1,000 tons. China ranks first, with an output of 41,000 tons, accounting for 53% of the global total, followed by South Africa, with 21,000 tons of output, ranking second in the world, accounting for 27% of the global total and Russia ranks third, with an output of 15,000 tons.
The Application of Vanadium in the Industry
Vanadium has many excellent physical properties and chemical properties, so the use of vanadium is very wide, known as the metal "vitamin". Most of the vanadium was initially used in steel. By refining the structure and grains of steel, the grain coarsening temperature was increased, thereby increasing the strength, toughness, and wear resistance of steel.
The Effect of Vanadium on Human Health
Vanadium is an essential trace element for the human body, which plays an important role in maintaining the growth and development of the body, promoting the growth of bones and teeth, promoting hematopoietic function, and increasing body immunity. An appropriate amount of vanadium can also lower blood sugar, blood pressure, blood lipids, increase myocardial contractility, and prevent heart disease.Later, people gradually discovered the excellent improvement effect of vanadium in titanium alloys, and applied it to the aerospace field, thus making a breakthrough in the aerospace industry.

The Flowsheet of Vanadium Extraction Process
Repulping and Leaching
The accumulated and drained slime tailings are excavated from Ponds No. 1 and 2 at the rate of 100 to 150 tons per day on a three shift basis using a front end loader. The slimes are repulped with solution from Pond No. 4 to about 50% solids in a ground level sump using three stainless steel Turbine-Type Propellers. The repulped slimes are pumped to three 8′ x 8′ Leach Agitators arranged in series. Sulphuric acid is added to a pH of 1.0 to dissolve the vanadium. Retention time in the agitators is approximately six hours. The leached slurry is pumped to an ingenious system of excavated ponds which serve as washing and decantation vessels in place of conventional thickeners. Pond No. 3 receives the leached slurry together with the current slime tailing from the RIP uranium circuit. The vanadium-bearing ("blue liquor") is piped from Pond No. 3 through a decantation tower to Pond No. 4. A sump-type pump and Propeller Agitator mounted on pontoons in Pond No. 3 are used to mix and transfer the solids from this pond to Pond No. 7 where the solids are combined with the raffinate from the subsequent vanadium SX circuit. The solution from Pond No. 7 is returned to Pond No. 3 using a trestle mounted pump which can be lowered or raised to compensate for the level of the pond. Ponds No. 3 and 7 serve as washing ponds whereas Pond No. 4 is a clarifying pond. The final tailing is allowed to accumulate in Pond No. 7.
EMF Adjustment
The clarified "blue liquor" from Pond No. 4, except for that portion recycled to the initial slime repulper, is pumped to the EMF adjustment circuit consisting of three 12′ diameter X 10′ deep Reducer Type Agitators in series. The agitators are constructed of wood stave tanks which are equipped with wood shafts and paddles to resist corrosion and impart mild agitation. Steam and powdered iron are added to the first agitator to produce an EMF of approximately 250 millivolts. This step reduces all ferric iron to the ferrous state and insures that all vanadium has been reduced from pentavalent to quadrivalent form. The steam is used to promote the reaction rate between the powdered iron and acid.Anhydrous ammonia is added to the discharge of the No. 3 EMF adjustment agitator to produce a pH of 1.65 prior to passing to a precoat pressure filter for removal of carbon, slimes, and unreacted iron.
Solvent Extraction
The filtrate is then treated through six stages of solvent extraction consisting of two 3-stage mixer-settler units in series to extract the vanadium. The organic extractant is a kerosene solution containing 6% di-2-ethyl-hexyl phosphoric acid and 3% tributyl phosphate. Anhydrous ammonia is added to the fourth stage mixer to adjust the pH to 1.7. The raffinate, after passing through an organic scavenger tank, is pumped to Pond No. 7 for dilution purposes.Two 31′-6″ diameter x 9′ deep Solvent Extraction units are used for recovery of the vanadium. Each of these units is divided into three main compartments which constitute the mixer-settler stages. Vertical Pumping Turbines are used in the mixers which permit the counter-current flow of aqueous and organic from stage-to-stage without the use of pumps or airlifts.
