Technology of extraction of vanadium from chloride waste by organization of production of vanadium pentoxide
The main source of vanadium mining is vanadium-containing ores, primarily titanium-magnetite.
The world has also accumulated a large volume of man-made waste from metallurgical and chemical industries, which can serve as raw material sources for obtaining vanadium. Large-scale processing of industrial waste is one of the ways to improve the environmental safety of our planet.
Pure vanadium has high strength, softness and is not magnetic.
In most qualities, it is similar to titanium. Vanadium is one of the most common elements used to improve the physical, chemical and mechanical properties of steels. This metal is an irreplaceable alloying element with a virtually unlimited scope of application in steels and alloys of a wide variety of classes and purposes. The level of mechanical and other properties that correspond to vanadium steel – special viscosity and strength.
APPLICATION
- Nuclear-hydrogen energy
- Aerospace engineering
- Chemical power sources
- Catalyst in the production of sulfuric acid Steel production
- Vanadium-containing steels and alloys are widely used in aviation, space technology, shipbuilding, industrial chemistry and nuclear energy
- Textile industry
- Glass industry
- Paint and varnish industry
- Agriculture
PRODUCTION
JSC “Titanium Institute” has a technology for extracting vanadium from chloride waste of titanium-magnesium production with the organization of vanadium pentoxide production. 3 technology options have been developed.
A pilot plant project for obtaining vanadium pentoxide has been completed.
MAN-MADE RAW MATERIAL SOURCES
Along with natural geological formations, there are many types of man-made raw materials that can contain significant industrial concentrations of vanadium. They can be conditionally divided into the following groups:
- ashes, ash and slag, slag, sludge, dust from thermal power plants and hydroelectric power plants operating on fuel oil and certain types of energy coal;
- solid and liquid waste from the oil refining industry.The United States extracts 2/3 of its vanadium from oil and its refined products;
- waste from titanium production;
- industrial solutions and “red mud” from alumina and aluminum production;
- slag from metallurgical plants that operate on iron ores enriched with vanadium;
- hydromineral raw materials, which are mine waters of coal, iron ore and other deposits.
