GB/T 1871.5-1995 for phosphate rocks and phosphorus concentrates. The standard provides flame atomic absorption spectroscopy (AAS) and volumetric methods for the determination of oxidation mg content. In the mining, processing and application of phosphate rocks and phosphorus concentrates, oxidation mg content affects product performance and mass. These two determination methods provide choices for relevant enterprises and testing institutions, standardize the detection process, help to accurately determine the oxidation mg content, and provide a basis for the rational utilization of phosphate rock resources and product mass control.
