This standard specifies the method for the determination of the total amount of rare earths in ionic rare earth ore by Inductance Coupled Plasma Mass Spectrometry (ICP-MS), which is suitable for the determination of the total amount of rare earths in the range of 0.010% to 0.50%. The standard provides an important basis for the mass assessment of rare earth ore resources through accurate analysis methods.
