| Abstract: | The inductively coupled plasma atomic emission spectrometry was applied in the phase analysis of iron ores, and pretreatment methods of different phases have been introduced in detail. Magnetite deposit can be gained after magnetic separation, and determined by using potassium dichromate volumetric method. Siderite, hematite limonite, iron sulfide and iron silicate can be determined by the inductively coupled plasma emission spectrometry. In this paper, the instrument conditions, solvent selection and the impact of media solutions have been discussed. The results are not different with the capacity assay results, so this method can be used to determine the phase of iron ores. |
