XRF detection (X-ray fluorescence spectroscopy) is a method for determining the types and contents of trace elements in substances, and is widely used in substance component analysis, for example, in the analysis of the types and contents of elements in metal-containing solid materials in raw ores during non-ferrous metal smelting. The XRF detection technology can be used for realizing accurate detection on the types and the contents of the corresponding elements contained in the raw ore relatively quickly and effectively, thereby meeting the control requirement of the nonferrous metal smelting process.
According to the XRF test principle, after the tested sample is excited by X-ray, the sample generates laser spectrum, the energy spectrum generated by different kinds of elements with different contents is different in wavelength and energy level, and the energy spectrum photons are counted by a receiver and then converted into count values, so that the contents of the elements are known. For metal-containing solid materials, physical properties such as granularity, compactness and the like of a detection sample have great influence on the precision and accuracy of XRF detection results. Therefore, before XRF detection, serial sample preparation and pressing pretreatment operation is required to be carried out on the metal-containing solid materials, so that detection samples have the same or uniform physical properties, and a detection model algorithm corresponding to the material samples with the physical properties is built, thereby maximally reducing the influence of complex factors on detection results.

Therefore, the pretreatment and detection processes of the metal-containing solid materials are limited by complicated terrains and working conditions, and involve more equipment, so that the metal-containing solid materials are difficult to install and deploy properly in an industrial field.
