Preparation of Nine Iron Ore Reference Materials of GFe-1~GFe-9

  • Nine standard reference iron ore samples of GFe-1~GFe-9 were developed. The concentrations of TFe of the samples ranged from 20.17% to 66.87%, which covered a wide iron concentration range from concentrated iron ore powder to poor iron ores and can meet the needs for iron ore exploration and ore-dressing. Powder XRF technique was used for homogeneity test and the analytical results indicated that all elements tested were in good homogeneity. A multi-laboratory collaborative analysis scheme was adopted in the certification procedure and thirteen accredited laboratories participated in the certification. 13 elements were certified and H2O data were provided as a reference value.
