Recently, two national standards, led by the Provincial Tungsten and Rare Earth Quality Inspection Center, were officially released on January 24, 2025: GB/T 6150.19-2025: Methods for Chemical Analysis of Tungsten Concentrates-Part 19: Determination of Fluorine Content-Ion-Selective Electrode Method and GB/T 6150.20-2025: Methods for Chemical Analysis of Tungsten Concentrates-Part 20: Determination of Mercury Content-Direct Solid Sampling Method. The release of these two new standards not only standardizes the analytical methods for detecting fluorine and mercury content in tungsten concentrates, improving the accuracy and comparability of test results, but also facilitates research on environmental pollution issues during the production and processing of tungsten concentrates. This provides strong support for the implementation of the national ecological and environmental protection strategy.
