Called rare earths (RE or R). Oxide of rare earth element oxides refers to the periodic table atomic numbers 15 kinds of lanthanide oxide 57-71, and the lanthanide and chemical properties similar to scandium (Sc) and yttrium (Y) a total of 17 elements . Rare earth elements in the field of petroleum, chemical, metallurgy, textiles, ceramics, glass, magnetic materials have been widely used, with the advancement of technology and application of breakthrough technologies, rare earth oxide value will increase. China rare earth deposits in the geographical distribution of a wide range of features and relatively concentrated. So far, geologists have found that thousands of the deposits and mineralization occurrences in the country of origin more than two thirds of the provinces (regions), in addition to the Bayan Obo in Inner Mongolia, southern Jiangxi, Guangdong, northern Guangdong, Sichuan Liangshan is concentrated distribution of rare earth resources outside the region, Shandong, Hunan, Guangxi, Yunnan, Guizhou, Fujian, Zhejiang, Hubei, Henan, Shanxi, Liaoning, Shaanxi, Xinjiang and other provinces are also rare earth deposits found, but the amount of resources than the rich mineral concentrate much less set region. 98% of the country's total distribution of rare earth resources in Inner Mongolia, Jiangxi, Guangdong, Sichuan, Shandong and other regions, forming a distribution pattern of north, south, east, west, and has a north south light weight distribution characteristics.
