Scope: This standard specifies the requirements, test methods, inspection rules and signs, packaging, transportation, storage and quality certificates of ionic rare earth ores and mixed rare earth oxides. This standard is applicable to mixed rare earth oxides of ion-type rare earth ores prepared by chemical methods using ion-adsorbed rare-earth ores as raw materials. It is mainly used as a raw material for grouping rare earth enrichment or separating a single rare earth compound.
