A brief history of vanadium mining
In 1830, Swedish scientists SAF Storm (NGSefstrom) from Sweden found that Tabu Ge (Taberg) iron ore mine in vanadium salts because of its bright color beautiful, so beautiful Scandinavian goddess Fanna Diss is named Vanadium. In May there, trivalent vanadium compound and a pentavalent vanadiumè´é½åˆ©é˜¿æ–¯(Berzelius) found in the laboratory, but he has never made the metal vanadium. It was not until 1869 that the British chemist HERoscoe first produced metal vanadium by reducing vanadium chloride by oxygen.
After the discovery of vanadium in steel at the end of the 19th century, the mechanical properties of steel were significantly improved, and the industry began to pay attention to vanadium. The earliest foreign development of vanadium from the perspective of mining began in the beginning of this century, people extracted vanadium from the green sulfur vanadium ore of the Peruvian asphalt uranium mine. At its peak, Peru's vanadium production once accounted for a quarter of Western vanadium production. Due to the increase in demand, in the 1930s, the United States launched a production process using the potassium uranium uranium mine in Colorado as a raw material to recover uranium while recovering vanadium as a by-product or a single production of vanadium. Then vanadium uranium was discovered in Australia and the former Soviet Union. In the mid-1950s, due to advances in smelting technology, it was developed to smelt vanadium- titanium magnetite to obtain converters for blowing vanadium slag; first, in Finland and South Africa, and then in small countries in Norway and Chile. In the early 1960s, the former Soviet Union began to exploit vanadium-titanium magnetite on a large scale, making vanadium-titanium magnetite the main raw material for vanadium extraction.
The development and utilization of vanadium in China began in the early days of the founding of New China. In the first 20 years, vanadium was mainly extracted from stone coal . The supply of vanadium has been in a state of short supply, and it is insufficient to make up for it. After the 1960s, with the construction of Zhihua Iron and Steel Base and the investigation of vanadium-titanium magnetite survey and the comprehensive utilization of vanadium and titanium technology, especially in 1987, the process of extracting associated vanadium from Panzhihua vanadium-titanium magnetite was put into operation. The situation of vanadium relying on imports has fundamentally changed.
The mid-1970s, due to the stone coal vanadium extraction technology matures, an important source of China's abundant coal resources has become a stone vanadium.
