Rare is the chemical periodic table of lanthanides - lanthanum (La), cerium (Ce), praseodymium (Pr), neodymium (Nd), promethium (Pm), samarium (Sm), europium (Eu), gadolinium (Gd ) , terbium (Tb), dysprosium (Dy), holmium (Ho), erbium (Er), thulium (Tm), ytterbium (Yb), lutetium (Lu), and the lanthanide elements 15 are closely related to two elements - scandium (Sc) and yttrium (Y) of 17 kinds of elements, called rare earth elements (Rare Earth). Referred earth (RE or R). Computers, televisions, mobile phones, cars , windmills, a lot of material to be used in rare earths. China controls 97% of rare earth market , Inner Mongolia has the world's largest rare earth mine . America used to be the main producer of rare earth materials , but now many American rare earth mines were shut. China 's cheap rare earth and labor , and fewer environmental restrictions , and the exploitation of rare earth is very difficult, part of the production process toxic and more likely to have radioactivity. Many are open-pit mining of rare earth ore . Production of one ton of rare earth will cause the loss of 300 square meters of topsoil . 2010 China exported 30,009 tons of rare earth materials . Now China provides for an annual export only 30,000 tons , China said export restrictions for environmental protection . In fact, many countries have rare earth reserves. They will exploit it ?
