The data illustrates the major countries in rare earth mine production worldwide from 2012 to 2017, measured in metric tons REO. In 2012, China had a mine production of some 100,000 metric tons of rare-earth oxide. Until 2017, the amount produced increased to some 105 thousand metric tons. The following elements are among rare earths: cerium (Ce), dysprosium (Dy), erbium (Er), europium (Eu), gadolinium (Gd), holmium (Ho), lanthanum (La), lutetium (Lu), neodymium (Nd), praseodymium (Pr), promethium (Pm), samarium (Sm), scandium (Sc), terbium (Tb), thulium (Tm), ytterbium (Yb), and yttrium (Y).
