Abstract：The chemical valence of manganese in manganese ore sample was studied. It was found that, the chemical valence of manganese in singly-ignited sample was the same to Mn3O4 and similar to MnO in fused piece. Accordingly, the relationship between the determination method of loss on ignition and the chemical valence of manganese in matrix effect correction was identified. A X-ray fluorescence spectrometric determination method of major and minor components in manganese ore was established. The analytical results of this method were in good agreement with the certified values and the mean value of parallel tests of several certified reference materials. The relative standard deviations (RSD, n=7) of main components in manganese ore were smaller than 2%. The RSD of Mn and Fe was 0.20% and 0.16%, respectively, which could meet the determination requirements of components in manganese ore.
