Our extensive distribution of vanadium titanium magnetic iron ore deposits, abundant reserves, reserves and production ranks third in the country's iron ore, has proven reserves of 9.83 billion t, prospective reserves of 300 million tons, mainly distributed in Sichuan Panzhihua - Xichang area, Hebei Chengde area, Shaanxi Hanzhong area, Hubei Fuyang, Fuyang area, Guangdong Xingning and Shanxi Daixian. Among them, Panzhihua-Xichang area is the main metallogenic belt of China's vanadium-titanium magnetite. It is also one of the important production areas of similar deposits in the world. It is about 300km long from north to south. It has 7 large and extra-large deposits, and medium-sized deposits. Where. The chemical composition of the ore and mineral processing products are shown in Table 1 and Table 2.
