Scope
This method specifies the determination method for the distribution of fifteen rare earth element oxides in ionic rare earth ores and mixed rare earth oxides. This method is applicable to the determination of the distribution of fifteen rare earth element oxides in ionic rare earth ores and mixed rare earth oxides (TREO≥80%). The determination range (mass fraction) is 0.20% to 99.00%.
