Foreword
This standard is drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces YS/T 433-2001 "Silver Concentrate". This standard compared with YS/T 433-2001, the main changes are as follows.
--- increase the product classification, according to the different grades of silver concentrate, divided into three grades;
- silver in the silver concentrate from the original not less than 3000g/t reduced to not less than 2500g/t;
--- delete the original standard "process" classification restrictions;
--- remove the lead, zinc, copper, bismuth, magnesium oxide, silica, aluminum oxide and other impurity elements of the limited requirements;
The limit of arsenic is reduced from the original 0.4% to 2.5%
- increased natural radioactive limits for non-ferrous metal minerals;
--- Sampling method changed from YS/T 96 to GB/T 14263;
--- increase the 800kg and other forms of silver and other bags of specific sampling requirements;
--- delete the "inspection lot is not greater than 60t" limit;
--- increase the appearance of the product quality inspection methods;
To increase the number of samples from the original three to four;
--- increase the arbitration results and test results appear to determine the deviation of the method.
This standard is proposed by the National Committee for Standardization of Nonferrous Metals (SAC/TC243).
