Rare Earth Full Analysis and Detection

Rare Earth Full Analysis and Detection
Rare earth minerals mainly exist in the form of minerals in the earth's crust, and there are two main types of occurrence states: as the basic constituent elements of minerals, rare earths are present in the mineral lattice in the form of ionic compounds and constitute indispensable components of minerals. Such minerals are usually called rare earth minerals, such as monazite and bastnaesite.

Rare earth classification
The 17 rare earth elements are usually divided into two groups according to the characteristics of the electronic layer structure and physical and chemical properties of the rare earth element atoms, as well as their symbiosis in minerals and different ion radii that can produce different properties.

Classified by mineral characteristics:
Cerium group (light rare earth)-lanthanum, cerium, praseodymium, neodymium, promethium, samarium and europium;
Yttrium group (heavy rare earths)-gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium and Scscandium kàng.

Classified by extraction separation:

Light rare earth (P204 weak acidity extraction)-lanthanum, cerium, praseodymium, neodymium;
Middle rare earth (P204 low acidity extraction)-samarium, europium, gadolinium, terbium and dysprosium;
Heavy rare earth (P204 acidity extraction)-holmium, erbium, thulium, ytterbium, lutetium, yttrium.
