In nature, vanadium is difficult to exist in a single body, mainly forming symbiotic ore or compound ore with other minerals. Now find contain vanadium mineral there are more than 70, but the main minerals have the following 3 kinds: vanadium titanium magnetite (in the world except the United States v extraction from potassium vanadium uranium, other countries mainly produce vanadium in extracting vanadium from vanadium titanium magnetite); Potassium vanadium uranium ore (a major source of this mineral in the United States and elsewhere); Petroleum-associated ore (a mineral that lives in crude oil and is increasingly important in central American countries because of its abundance). At present, 98% of the proven reserves of vanadium resources are found in vanadium titanium magnetite, and the content of V2O5 can reach 1.8%.
China is rich in vanadium resources and is a large global reserve of vanadium resources. Vanadium resources are widely distributed in 19 provinces and cities (regions) in China, but they are mainly concentrated in panzhihua region of sichuan province and chengde region of hebei province, especially panzhihua region. There are two main types of vanadium mineral resources in China, vanadium titanium magnetite and vanadium bearing stone coal. The latest survey shows that in 2013 the ministry of land and resources (data), only vanadium titanium magnetite in panzhihua. Reserves of 23.743 billion tons, including vanadium resources reserves of 18.62 million tons, in the domestic first, the third in the world. Vanadium resources are also distributed in hunan, guangxi, gansu and hubei provinces. In recent years, the geological prospecting fund of sichuan province has assisted the geological prospecting, and the geological prospecting of the whole province has achieved remarkable results. By the end of 2012, 4.4 billion tons of vanadium titanomagnetite, 16.36 million tons of titanium and 8 million tons of vanadium were discovered.
China also has a lot of stone coal vanadium resources, belongs to the low grade vanadium resources and vanadium content of stone coal vanadium ore with total reserves of stone coal vanadium ore resource in the world, containing vanadium from stone coal are mainly distributed in hunan, guangxi, hubei provinces in our country. The total stone coal reserves are 6.188 billion tons, including 3.9 billion tons of proven industrial reserves and 77.75 million tons of reserves containing more than 0.5% vanadium pentoxide.
In addition to China, other countries in the world are still rare in industrial exploitation and utilization, so stone coal is the characteristic raw material of China. Under the current technology, the grade of vanadium pentoxide reached more than 0.8% of the stone coal is the industrial production value, that accounts for about 20% of the total reserves of stone coal - 30% is greater than its recoverable reserves vanadium titanium magnetite, therefore, in stone coal as raw material to produce vanadium products in our country has a good development prospect.
