Abstract: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.
Keywords:iron ore  reference material  certified value  uncertainty
