Abstract： The medium, low and trace tin in ore were measured on atomic emission spectrometer by selecting several wavelength lines with different sensitivities. K2S2O7, Al2O3 and NH4I were used as buffer agent, and Ge was used as internal standard. The sample was loaded by deep-hole electrode. This method effectively broadened the measuring range of tin. The content of tin in range of 0.001%-10% in ore could be determined. This method was applied to the determination of standard sample and unknown sample. The results were compared and verified with iodometry. It was found that, the determination results were consistent with those obtained by chemical method. The relative standard deviation (RSD, n=12) was less than 5%. This method could be used in the determination of tin in various ores with different content range.
