摘　　要：对含铅重晶石中硫酸钡的重选试验的流程分析建立分析方法.试样用0.6 mol/L盐酸处理,除去碳酸钡、硫酸钙、铅及铁等杂质,采用铬酸钡容量法与电感耦合等离子体原子发射光谱法（mP-AES）进行含铅重晶石重选试验中硫酸钡分析.ICP-AES法测定硫酸钡范围0.0005％ ～ 15％,铬酸钡容量法测定硫酸钡范围：10％ ～ 99.9％.应用于重选硫酸钡试验回收,平衡效果良好.The analysis methods for determination of barium sulfate content in lead-bearing barite have been established for analyzing the test flow of barite gravity separation.The sample is treated by 0.6 mol/L hydrochloric acid to remove barium carbonate,calcium sulfate,lead,iron and the other impurities,the barium sulfate in the lead-bearing barite gravity separation test is analyzed by barium chromate volumetric method and inductively coupled plasma atomic emission spectrometry （ICP-AES）.The barium sulfate determination range by ICP-AES is 0.0005％ ～ 15％,the barium sulfate determination range by barium chromate volumetric method is 10％ ～ 99.9％.The barium sulfate content determination results can meet the requirement of analyzing the flow of barite gravity separation satisfactorily.
