摘　　要：建立了一种连续测定铀矿石水冶尾渣中铀含量的方法,同时提供一种使用该方法的装置。开展模拟实验对测定参数进行优化,随后进行对比实验对分析精度进行论证。相关实验结果表明:当样品厚度大于200mm时即可忽略样品厚度对测量的影响,加水量为1.2L/min时可以使矿渣连续均匀的排出;相对误差≤30%的样品为94%,符合控制分析的基本要求。A method for the continuous determination of uranium content in the tailings of Uranium ore hydrometallurgy is established,and a device for using this method is 643 provided.Simulation experiments were carried out to optimize the parameters,and then the analytical accuracy was demonstrated by comparative experiments.The results show that when the thickness of the sample is more than 200 mm,the influence of the sample thickness on the measurement can be ignored,and the slag can be discharged continuously and evenly when the water quantity is 1.2 L/min,and the relative error^30%of the sample is 94%.Meet the basic requirements of control analysis.
