Simultaneous determination Of Cu Pb Zn and Ag By ICP-OES in the ore of high altitude
MA Jiang-ying;Western Mining Group Company with limited liability-Sichuan Xinyuan Mining Company with limited liability;
Aimed at high altitudes ore samples analysis, the use of HCL + HNO3 decompose ore samples,inductively coupled plasma spectrometry(ICP-OES) determine Cu Pb Zn and Ag of the ore.To determine the best working conditions, choose the best analytical spectral lines. The detection limit of each element is Cu 0.003 μg/m L,Pb 0.03 μg/m L,Zn 0.04 μg/m L,Ag 0.006 μg/m L.Through verification of standard substance and agreemented with outside inspection values of Beijing Research Institute of Mining and Metallurgy, the determination results are within the error range.The methoed has good precision and accuracy,can be used in the production of large quantities of iron ore in the rapid determination of Cu Pb Zn and Ag.
