Fluoride Technology of Processing Oxides of Rare Earth Elements
The paper describes the advantages and characteristics of the fluoride technology applicable for the recovery of oxides of rare earth elements with the help of a fluorinating agent of elemental fluorine. A metallurgical mixture (2.5 m2/g) of rare earth elements oxides of the cerium subgroup, containing % wt.: CeO2 - 50-55; La2 O3 - 23-25; Pr6O11 - 6-9, and Nd2O3 - 13-16 were studied. It has been shown, that using fluoride technology allows recovering mixture of rare earth elements with outlet no less than 98.9 %.
