摘要

摘要: 采集制备了9个铁矿石标准物质,全铁含量为20.17％~66.87％,涵盖了贫铁矿至铁精矿粉,能满足铁矿勘查和选冶的需要。采用精度相对较高的测试方法进行均匀性检验,结果表明样品均匀性良好。选择13家具有丰富经验的实验室采用不同原理的方法进行定值测试,定值项目14种,其中13种组分提供标准值,H₂O^＋提供参考值。

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.
