XB/T 630.1-2023 (Methods for chemical analysis of recycled materials from rare earth pyrometallurgical smelting - Part 1: Determination of total rare earth content) is available as an English-translated PDF.

XB/T 630.1-2023 — This standard specifies the method for the determination of the total amount of rare earths in recycled materials from rare earth pyrometallurgy.

This standard is applicable to the determination of the total amount of rare earths in recycled materials from rare earth pyrometallurgy by electrolysis process and thermal reduction process.

This standard contains a total of 2 methods: oxalate gravimetric method (Method 1) and inductively coupled plasma optical emission spectrometry (Method 2). The measurement range (mass fraction) of method 1 is 5.00% to 90.00%, and the measurement range (mass fraction) of method 2 is 0.50% to 10.00%.
