The rare earth elements exist in the form of carbonates, fluorides, phosphates, oxides or silicates in rare earth ore concentrate. Usually, they are poorly soluble in water. After a variety of chemical changes, they are transformed into compounds which are soluble in water or mineral acid. Then after dissolution, separation, purification, concentration or burning processes, they are made
