前言近十年来X荧光分析技术日益广泛应用于选矿厂快速分析矿浆中的金属品位,它已成为实现选矿生产过程计算机控制的基础和必要条件。这种技术的典型产品是芬兰奥托昆普公司的库里厄—300型载流分析系统,其工作原理和系统构成已有文章介绍。由于X荧光光谱仪给出的信息是X射线强度,它是被测样品中元素含量的相对代表量而不是金属品位值,尤其是在选矿厂矿浆中经常含有其它共生元素,其X射线强度相互影响,矿浆浓度又经常波动,因此为了使X荧光分析仪得到满意的分析精度,不仅仪器本身质量要高而且在很大程度上取决于标定工作的好坏。标定技术属于X荧光分析仪
Preface X-ray fluorescence analysis technology is widely used in mineral processing plants to rapidly analyze the metal grade in the past decade. It has become the foundation and necessary condition for the computer control of the beneficiation process. A typical product of this technology is the Curie-300 Carry Current Analysis System from Outokumpu, Finland. The working principle and system configuration are described in the article. Since the information given by the X-ray fluorescence spectrometer is the X-ray intensity, which is the relative representation of the elemental content in the sample being tested rather than the value of the metal grade, in particular in the ore pulp of the concentrator often containing other intergrowth elements whose X-ray intensities interact Therefore, in order to obtain satisfactory analytical accuracy of the X-ray fluorescence analyzer, not only the quality of the instrument itself is high, but also largely depends on the quality of the calibration work. Calibration technology belongs to X fluorescence analyzer
