Abstract: In order to enable the coal preparation plants to standardize and unify the methods for measuring the percentage (by mass) of secondary slime generated in wet cleaning process, the standard GB/T 40503—2021 measuring methods for secondary coal slime content in coal preparation plant was jointly issued by China National Administration of Market Supervision and Administration and China National standardization Management Committee on August 2021, and the standard wit go into effect on March 1, 2022.
