Abstract：The content of lead-zinc ore was analyzed using the hand-held X-ray fluorescence spectrometer. The rapid analysis method of lead, zinc, copper and molybdenum in lead-zinc ore on site was established. According to the energy position of testing elements, the optimal voltage of 35 kV was selected. The determination results of Al, Ti and Ni filter leafs were compared. The detection limit of Mo could be effectively reduced using Ni filter leaf and 4 mm collimator. The direct detection without sample preparation was adopted to meet the analysis requirements of actual samples on site. The surface state of various samples was calibrated by the mathematical model, realizing the quantitative analysis of block, crumb and powdered samples on site. The proposed method was applied to the determination of Pb, Zn, Cu and Mo in standard samples and actual samples. The found results were consistent with the certified values or other methods. The accuracy deviation could meet the requirements of mineral separation. The proposed method exhibited good repeatability and short determination period. It had been applied to some domestic large lead-zinc mining bases.
