Research on the key technology of high-precision electron probe in the detection of mineral composition

With the gradual deepening of the development of mineral resources, people's demand for accurate detection of mineral components is also increasing. High-precision electron probe technology has become an important tool in mineral composition detection due to its efficient micro-chemical composition analysis. In this paper, we will discuss the application of high-precision electron probes (EPMA) in the detection of mineral composition, focusing on the key technical factors that affect the accuracy of its analysis. Based on the comprehensive application of theoretical analysis and empirical experiments and data analysis methods, some of the operating parameters are optimized, and the content changes of various components such as iron, zinc, cadmium and other components in minerals under different geological conditions are analyzed. The results show that the adjustment of the analysis parameters of the high-precision electron probe can significantly improve the accuracy and reliability of the mineral composition detection process, and provide strong scientific support for the evaluation of mineral resources and geological exploration.
