Scope

This document is applicable to the determination of the total rare earth content in recycled materials from rare earth pyrometallurgical recovery processes, including electrolytic and thermal reduction processes. This document contains two methods: oxalate weight method (Method 1) and inductively coupled plasma emission spectrometry (Method 2). The determination range (mass fraction) of Method 1 is 5.00% to 90.00%, and the determination range (mass fraction) of Method 2 is 0.50% to 10.00%. When the determination ranges of the two methods overlap, Method 1 shall be used as the arbitration method.
