| Abstract: | his paper proposed an analysis method for using a Jp-303 type Intelligent Polarograph to determine high tungsten content （higher than 1%） in the ore. Comparing with conventional thiocyanate spectrophotometric method , the proposed method is faster, easier, more accurate and has wider analysis range （the content of WO~ can be from XQ/＇~0 to XX% ）. The correlation coefficient of the calibration curve is over 0. 999. The standard addition recovery is 98.4%. This method can be used for production control analysis in beneficiation and metallurgy industry with satifictory results. |
