稀土

Ago a kind of misconception that the rare earth metals is very scarce in nature, in fact not the case, many of which elements such as lanthanum, cerium, praseodymium, neodymium and samarium in accordance with their distribution in nature is no less well-known people in some of the elements of industry, common There ore monazite, scandium yttrium stone, silicon and cerium stone, stone and brown curtains and other fluorocarbon calcium cerium ore.
