| There are six types of vanadium deposits in China: sedimentary type, magmatic type, sedimentary metamorphic type, volcanic type, weathering type and hydrothermal type, among which sedimentary type and magmatic type of vanadium deposits account for more than 90% of vanadium resources in China. Sedimentary vanadium deposits are mainly located at the margin of Tarim, Yangtze and southeast margins of Yangtze platforms, while magmatic vanadium deposits are mainly located at the Emei Mountain large igneous province, the Tarim large igneous Province and the north margin of North China Craton. Vanadium ore is China's dominant mineral, vanadium metal reserves account for the world's third, the annual output of vanadium accounts for about 60% of the world. Sedimentary vanadium ore is seldom used due to low grade, high mining cost and environmental protection policies. Vanadium titanium-magnetite in magmatic vanadium ore is the main raw material of vanadium. It is suggested to strengthen the mining, technical research and environmental protection of sedimentary vanadium ore, and continue to increase the comprehensive utilization of vanadium resources in magmatic vanadium titanium magnetite, so as to realize the green, high quality, high efficiency and economic utilization of vanadium ore resources in China. |
