Foreword

Instead of the standard YS/T 318-1997 "copper concentrate." Compared with YS/T 318-1997 "copper concentrate", this standard the main changes are as follows. --- Grade copper concentrate from the original four grades, the main grade of 13% to 30%, into five grades, the main grade of 13% to 32%. --- Chemical composition made appropriate adjustments, an increase of Hg, F, Cd, Sb and natural radioactive elements in impurity limits section control. --- Inspection rules on the scope and be part of a revision. This standard by the National Standardization Technical Committee of non-ferrous metals and centralized. This standard by Tongling Nonferrous Metals (Group) Company is responsible for drafting. This standard by Daye Nonferrous Metals Company, Jiangxi Copper Company participated in the drafting. This standard was drafted by assisted Jinchuan Group Limited. The main drafters of this standard. Sheng Zhongyi, Bushao Tian, Li Peng Hong, and from Shao, Zhangqi Gui, Li Baodi, Pan Jie, Zhang Zelin, Lin Hsiu-ying.
