GB/T 6150.17-2008 focuses on the determination of antimony content in the chemical analysis of tungsten concentrates, using hydride atomic absorption spectroscopy (AAS) method. In the mining, processing and application of tungsten concentrates, antimony content is one of the key indicators to measure the mass of tungsten concentrates, which affects the performance of subsequent products. The standard details the specific steps for the determination of antimony content by hydride atomic absorption spectroscopy (AAS) method, providing unified specifications for relevant enterprises and testing institutions, which will help to accurately determine the amount of antimony, control the mass of tungsten concentrates, and promote the orderly development of tungsten ore industry.
