Scope

This Standard specifies the method for determining total rare earth ion phase in ion type
rare earth ore.
This Standard is applicable to the determination of total rare earth ion phase in ion type
rare earth ore. It includes 3 methods: Method 1 Inductively Coupled Plasma Mass
Spectrometry; Method 2 Inductively Coupled Plasma Atomic Emission Spectrometry
and Method 3 EDTA Volumetric Method. The measurement range of Method 1 is:
0.010%~0.50%. The measurement range of Method 2 is: 0.020%~0.50%. The
measurement range of Method 3 is: 0.020%~0.50%. Among them, Method 3 is not
applicable to the determination of samples with an iron content greater than 10 after
leaching or a copper content greater than 5 [Translator’s note: This sentence of original
Chinese is ambiguous and incomprehensible].

Summary	This standard specifies the ion-type rare earth ore in the ion phase rare earth total amount of the determination method. This standard is applicable to the determination of the total amount of rare earth ions in ion-type rare-earth ore, including three methods: Method 1 Inductively Coupled Plasma Mass Spectrometry, Method 2 Inductively Coupled Plasma Atomic Emission Spectrometry and Method 3 EDTA volumetric method. The measurement range of method 1 is 0.020% ~ 0.50%, and the range of method 3 is 0.020% ~ 0.50%. Among them, the method 3 does not apply to the leaching solution after the iron content of more than 10 for leaching or copper content greater than 5 copper content of the sample is greater than the determination.
