This Standard serves as a replacement of YS/T 261-1994 Spodumene Concentrate. In comparison with YS/T 261-1994, there are several main changes as follows. ---The grade and chemical composition of spodumene concentrate are adjusted; ---The requirements for granularity of spodumene concentrate are adjusted. This Standard was proposed by and shall be under the jurisdiction of National Technical Committee 243 on Nonferrous Metals of Standardization Administration of China. The drafting organization of this Standard. Sichuan Tianqi Lithium Co., Ltd. The main drafters of this Standard. Yao Kailin, Jinpeng, Huo Liming, Xu Mingjiang, Zeng Yiwei, Liang Pingwei. The release of the previous versions of the standard replaced by this Standard is as follows. ---YS/T 261-1994. Spodumene Concentrate1 Scope
This Standard specifies the requirements, test methods, inspection rules, marking, packaging, transportation, storage, quality certificate and contract (or order form) content of spodumene concentrate. This Standard is applicable to spodumene concentrate, which is obtained through various mineral processing methods and enrichment. The spodumene concentrate has been extensively applied to the glass and ceramic industry, and the production of various chemical products of lithium.2 Normative References
