Determination of seven accompanying elements in concentrate fines by inductively coupled plasma atomic emission spectrometry

The samples were dissolved with HNO3 and HF.The content of seven accompanying elements(including Ag,La,Yb,Cd,Co,Ga and In) in three concentrate fines(copper,lead and zinc) were determined by inductively coupled plasma atomic emission spectrometry(ICP-AES).The optimal analytical lines for testing elements were selected by experiments.The matrix interference and interference between coexisting elements were discussed.Under the selected experimental conditions,the detection limit of method was 0.4-5.4 ng/mL,and the recovery of standard addition was 93 %-109 %.The proposed method was applied to the analysis of seven accompanying elements in three concentrate fines.The determination results were in good agreement with those obtained by ICP-MS,and the relative standard deviation(RSD,n=10) was 1.4 %-4.8 %.This method had instructive significance to the improvement of beneficial element recovery,and the comprehensive utilization of accompanying elements.
