GB/T 2462-1996 stipulates the determination of effective sulfur content in pyrite and sulphur concentrates by combustion neutralizing method. The standard clarifies the determination principle, details the requirements of combustion devices, absorption devices and other equipment, and standardizes the processes of sample preparation, combustion process, titration operation, etc. Through this standard, the effective sulfur content can be accurately determined, providing a basis for mass evaluation and trade settlement of pyrite and sulphur concentrates, helping relevant enterprises to control the quality of raw materials, ensure the efficiency of sulfur utilization and product mass in the production process, and promote the orderly development of the sulphur resource industry.
