GB/T 18882.2-2002 Chemical analysis methods for mixed rare earth oxide of ion-absorpted type RE ore-Determination of fifteen REO relative content--X-ray fluorescence spectrometric method (English Version)
This standard specifies the determination method for the proportion of fifteen rare earth element oxides in mixed rare earth oxides of ionic rare earth ores. This standard applies to the determination of the composition of fifteen rare earth element oxides in mixed rare earth oxides (TREO ≥ 80%) of ionic rare earth ores. Measuring range: 0.20% to 99.00%.
