The deposit includes more than 470,000 tons of critical rare earth elements, including praseodymium, neodymium, dysprosium and terbium, according to the CGS, a division of the Ministry of Natural Resources. Primarily consisting of medium and heav...
Rare earth elements are critical raw materials for both high-tech and green tech products, and they are critical for various defense-related products. For example, products as diverse as cell phones, hybrid automobiles, wind turbines, and weapons used by the United States military all rely on ...

A sign at the entrance of China’s Baotou, Inner Mongolia Pioneering Rare Earth Hi-Tech Zone quotes Deng Xiaoping’s 1992 claim: “There is oil in the Middle East, but there is rare earth in China.” The rare earth elements (REE) are a group of 17 chemically similar metallic elements ...
Rare earth elements are a nonrenewable and important strategic resource, and China is rich in these elements. However, the substantial exploitation of these resources has caused the migration, diffusion, transformation and accumulation of pollution sourc
Introduction The rare earth elements (REEs) consist of the 15 lantha-nide elements (La to Lu). Because of the increasing application of REEs and yttrium (REY) in high-and green-tech industries, the demand for the REY is projected to increase in the future. Rare earth elements are relative...
The distribution of rare earth elements (REEs) in red soil profiles in southern China was studied in detail. Much higher total REE contents were observed in red soils than in the bedrocks. The highest total REE contents were found in gneiss-, limestone- and granite- derived red soils and ...
Rare-earth elements (REEs) have been used in fertilizers in the agriculture of China for about 20 years. They have been shown to be beneficial elements for plants. For example, they have improved the yield and quality for several kinds of crops. This paper reviews the current literature on ...
Deep coal mines in northern Anhui province, China, provide opportunities for tracing the distribution and fractionation of rare earth elements (REEs) in deep seated environments. Major ions, as well as REE concentrations were measured in groundwater from a sandstone aquifer located between –400 and...
Rare earth minerals have been mined for more than 50 years in Inner Mongolia of China. In the mining area rare earth elements (REE) may be significantly accumulated in humans. Therefore, the aim of this paper is to characterize the REE concentrations in hair of local residents. REE concentra...
