1.: In 1831, Swedish chemist Seyverstom announced the discovery of vanadium while studying pig iron smelted in the iron ore mine of Tarberg, Sweden. Named Vanadium in the name of the goddess Vanadis. In 1882, the Luquelezotte Iron and Steel Works used the low-temperature sulfuric acid treatment method to extract vanadium oxide from Bessemer converter slag containing 1.1% V, which was used in the dye factory. In 1894, Muwasan produced ferrovanadium by reducing vanadium oxide in an electric furnace.
2.In 1897, Goldschmidt smelted by thermite, and the quality could meet the requirements for the production of vanadium steel. In 1924, Seth reported on the Vanadium-containing Iron Ore-Vanadium-Containing Pig Iron and Vanadium Slag Process proposed by Sweden, using vanadium slag as a raw material for the production of vanadium pentoxide and ferrovanadium. During the Japanese invasion of China, in 1942, German technology was introduced, and the construction of "Nanman Special Iron Co., Ltd." was started with Chengde vanadium titanium magnetite concentrate as raw material to produce ferrovanadium containing about 30% V.
3.In 1954, the Iron and Steel Industry Administration of the Ministry of Heavy Industry of the Ministry of Heavy Industry issued the scientific research task of "Vanadium Titanomagnetite Concentrate Pyrometallurgical Smelting and Extraction of Vanadium and Preparation of in Chengde Damiao". It was completed in 1955 and laid the foundation for the construction of China's ferrovanadium industry. In 1958, Jinzhou Ferroalloy Plant resumed the production of ferrovanadium from Chengde vanadium titanomagnetite concentrate as raw material. In 1959, the production of ferrovanadium from vanadium slag began. In 1978, Panzhihua Iron and Steel Company began to produce vanadium slag, making China enter the ranks of the world's largest vanadium producers.;
