Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
Instead of the standard YS/T 452-2002 "mixed lead and zinc concentrates." Compared with YS/T 452-2002, the main changes are as follows.
--- Increased mercury limit requirements;
--- Increased natural radioactivity limit requirements;
--- Three and four items from the product Cd content of not more than 0.35% and 0.40%, respectively, modified to not more than 0.40% and 0.50%;
--- As four product content of not more than 0.45% by the modification of not more than 0.40%;
--- SiO2 content is made not more than 4.5%, 5.0%, 5.5%, 6.0%, respectively, modified to not more than 4.0%, 4.5%, 5.0%, 5.5%;
--- Fe content of from 5% to 14% revised to 6% to 15%;
--- Removed Cu limited requirements;
--- Modification of the test batch;
--- Delete test items Terms of contents;
--- Sample prepared by the three revised to four, the addition of a sample arbitration; arbitration relating to international trade while the retention time of the sample were
Regulations;
--- Determination of test results has been modified.
