GB/T 6150.14-2008 《Methods for chemical analysis of tungsten concentrates - Determination of manganese content - The ammonium ferrous sulfate volumetric method and flame atomic absorption spectrometric method》 Related products

This standard specifies two methods for the determination of manganese content in tungsten concentrates: ammonium ferrous sulfate volumetric method and flame atomic absorption spectroscopy (AAS) method, which are suitable for the determination of manganese content in the range of 2% to 20%. Methods The manganese content is determined by phosphoric acid analysis of the sample, using ammonium persulfate oxidation, and then by titration or Light spectrum method. This standard provides reliable technical support for the analysis and quality control of tungsten concentrates to ensure that the product composition meets the requirements.
