Foreword
This Standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This Standard replaces GB/T 20169-2006 Mixed rare earth oxide of ion-
absorbed type rare earth ore.
Compared with GB/T 20169-2006, the major technical changes in this Standard
are as follows.
— ADD the character grade (SEE Chapter 3);
— COMBINE eight grades into five grades (SEE Chapter 3);
— LIST the Y2O2 indicator in each grade individually (SEE Table 1);
— DELETE the indicator in each grade (SEE Table 1 in 2006
edition);
— MODIFY the indicator in each grade to (Pr6O11 + Nd2O3) content
indicator (SEE Table 1);
— MODIFY the indicator in each grade to (Sm2O3 + Gd2O3)
content indicator (SEE Table 1);
— MODIFY the Al2O3 content in non-rare earth impurities from 1.2% to 1.5%
(SEE Table 1);
— ADD the assessment indicator of each grade for non-rare earth impurity
SiO2 (SEE Table 1); and
— ADD the assessment indicator of each grade for loss on ignition (SEE
Table 1).
This Standard was proposed by and shall be under the jurisdiction of the
National Technical Committee for Standardization of Rare Earth (SAC/TC 229).
Major drafting organizations of this Standard. Jiangxi South Rare Earth High-
tech Co., Ltd, and Guangdong Zhujiang Rare Earth Co., Ltd.
Main drafters of this Standard. Chen Feiyu, Tao Yong, Zhang Shaofu, Xie Liyun,
Wen Shijie, Jin Yanhua and Wang Shuying.
The previous released edition of the standard substituted by this Standard is as
follows.
— GB/T 20169-2006.
Mixed rare earth oxide of
ion-absorbed type rare earth ore
1 Scope
This Standard specifies the requirements, test methods, inspection rules, and
symbols, packaging, transport, storage and quality certificate for the mixed rare
earth oxide of ion-absorbed type rare earth ore.
This Standard is applicable to the mixed rare earth oxide of ion-absorbed type
rare earth ore prepared by using the chemical method, where ion-absorbed
type rare earth ore is used as the raw material. The mixed rare earth oxide of
ion-absorbed type rare earth ore is mainly used as the raw material for grouping
rare earth aggregates or separating single rare earth compounds.
