Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. Instead of the standard YS/T 340-2005 "nickel concentrate," compared with the YS/T 340-2005, the main changes are as follows. --- A product of nickel concentrate from the Ni is not less than "9.5%" to "10%" five products of nickel concentrate from the Ni is not less than "5.5%" was changed to "5.0%"; --- Five product of nickel in concentrate by the MgO is not more than "12.0%" was changed to no more than "10.5%"; --- Added Hg, Cd, As, Pb, Zn and natural radioactive elements in impurity limits control requirements; --- Batch been adjusted to cancel the batch weight; --- The scope and detection rules have been revised in part; --- A reference to the standard has been adjusted. This standard by the national non-ferrous metals Standardization Technical Committee (SAC/T 243) focal point. This standard is mainly drafted by.
