First, rare earth ore

Rare earth minerals in the crust mainly in the form of minerals exist, there are three main states: As the basic composition of minerals, rare earth ions in the form of ions in the crystal lattice, constitute an essential component of minerals. Such minerals are commonly referred to as rare earth minerals, such as monazite, bastnaesite and the like. As an impurity element of minerals, it is dispersed in rock-forming minerals and rare-metal minerals in the form of isomorphism. Such minerals may be referred to as minerals containing rare-earth elements such as apatite, fluorite and the like. Ionized state is adsorbed on the surface of some minerals or particles. Such minerals are mainly all kinds of clay minerals, mica minerals. Rare earth elements in this state are easily extracted.
