ABOUT RARE EARTH
Which elements are rare earth elements?
Rare earth is a periodic table of the chemical elements in the lanthanide and their associated and similar elements collectively, which comprises 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 ).
Physical properties of rare earth metal
The main physicochemical properties of rare earth elements
Rare earth elements are typical metallic elements. Their metallic activity is second only to that of alkali metals and alkaline earth metals, but more active than other metal elements. In 17 rare earth elements, according to the active order of the metal, scandium, yttrium, lanthanum increase, from lanthanum to lutetium decrease, namely lanthanum is the most active.
What are the types of rare earth mines?
The occurrence state of rare earth minerals
Rare earth elements mainly exist in the form of minerals in the earth's crust, and there are three main occurrence states:
As the basic elements of minerals, rare earth occurs in the mineral lattice in the form of ionic compounds, which constitute the essential components of minerals. Such minerals are commonly referred to as rare earth minerals, such as monazite, bastnasite, etc.
