The demand for energy in today's social development is increasing,and nuclear energy is one of the cleanest and most efficient energy sources.Thorium resource is a potential new type of energy,and its content in the earth's crust is much higher than that of uranium resource.With the decrease of uranium resource reserves in the earth's crust,the exploitation and utilization of thorium resource has important strategic significance.In the current rare earth beneficiation technology,there is no better rare earth separation method.In order to improve the separation efficiency of rare earth,many scientific research teams at home and abroad have done a lot of research,and with the development of nuclear signal energy spectrum analysis technology,the issue of "sorting rate" rare earth separation rate has been solved to some extent.In the nuclear energy spectrum analysis technology,how to further process and analyze the nuclear signal generated in the process of rare earth ore processing has become the research focus of this paper.This article is a cross-application research of information science and ore processing analysis,the main research issue is how to select a suitable method to analyze and process the nuclear signal generated in rare earth ore processing.On the basis of the previous research,respectively adopted a digital shaping algorithm for processing X fluorescence signals and a Kalman filter algorithm for processing radioactive ? signal is respectively proposed,these two algorithms can analyze and process these two nuclear signals in a targeted manner,and realize the application of information technology in rare earth beneficiation.The main contents of this paper are as follows:Firstly,it introduces the research background and significance of the subject,the present stage of mineral processing analysis technology at home and abroad is discussed,and two optimal analytical methods in the process of rare earth processing: X fluorescence analysis,radioactive ? spectroscopy analysis technology.The two selected analysis techniques are essentially physical beneficiation technologies,they not only rely on the natural advantages of low pollution,but also low power consumption,making them popular among many beneficiation technologies,at the same time,it also uses nuclear signal analysis to carry out ore separation,so that the field of beneficiation is in line with information technology.Illustrates the different nuclear signal generation principle,by analyzing the principles and characteristics of different nuclear signals,targeted improvement of the corresponding treatment methods,in the processing of nuclear signals,it is necessary to analyze the final spectrum and energy spectrum at any time.for this reason,this paper designs a set of nuclear signal processing overall flow.Secondly,it is improved on the basis of traditional mineral processing technology,the beneficiation model that meets the current demand is designed,and the algorithm processing is carried out according to the relevant theoretical knowledge of nuclear signal.Use MATLAB and Quartus simulation software to compare the algorithm in this paper with other nuclear signal processing algorithms,and compare and evaluate the theoretical analysis,baseline recovery of pulse signals,X-ray fluorescence signal shaping results,and radioactive ? signal denoising filtering results.To verify whether the algorithm proposed in this article is effective.It can be clearly seen from the spectrum of signal shaping that the digital trapezoidal shaping algorithm used in this article has better resolution and good shaping effect;in the peak detection of radioactive ? signal,the signal processed by the Kalman filter algorithm is detected,the peak result is significantly increased than the original signal,algorithm filtering forming effect is better.It is concluded that the algorithm in this paper is suitable for the process of nuclear signal processing.Finally,the algorithm is verified experimentally with the nuclear signal actually collected.According to the design of mineral processing model to build the experiment environment.The rare earth deposits in Bayan Obo were detected by two kinds of mineral processing techniques,the collected signal is extracted,and the digital trapezoidal forming algorithm and Kalman filter algorithm are used for experimental verification.The experimental results show that the distribution of elements contained in the rare earth ore and whether there is radioactivity can be clearly identified by analyzing the spectral line results formed in the end,so as to verify the feasibility of the algorithm.In this paper,the digital signal processing technology is combined with the rare earth mineral processing technology,which provides an effective processing and analysis method for the nuclear signal processing part of the new mineral processing technology.The research content of this article will promote the application of digital signal processing technology in the field of ore processing,and provide reference and reference for the development of new ore processing technology.
