| Abstract: | The progress of analysis standard and the trend of proficiency testing of iron ore were summarized. The general situation for analysis of iron ore and the requirements on analysis of its chemical component were introduced. Through comparing the international standards (ISO standard) and national standards (GB standard) for chemical analysis of iron ore, several main determination indexes were analyzed. The proficiency testing schemes of iron ore conducted by China NIL Research Center for Proficiency Testing in recent years were presented, and several typical schemes were reviewed, including total analysis of iron ore CRMs, X-ray fluorescence spectrometric analysis of iron ore and valence state analysis of iron ore. |
