近年来国外已广泛采用x射线荧光光谱分析作为有色金属采矿、选矿、冶炼的流程控制分析。本文所研究的对象为干法矿样,其组成复杂,元素在其中所呈现的状态各不相同,试样的粒度不一致,而各元素的含量变动范围又很大。因此,如何消除试样的颗粒度影响,克服共存元素的基体效应,快速而准确地配合流程分析便是本法讨论的重点。为此采取了如下措施:以实际试样作标准试样;用振动磨样机计时磨样;采用经验系数法对共存元素 In recent years, foreign countries have widely adopted x-ray fluorescence spectrometry as a non-ferrous metal mining, mineral processing, smelting process control analysis. The object of this paper is the dry mineral sample, its composition is complex, the elements present in different states, the particle size of the sample is inconsistent, and the content of each element varies greatly. Therefore, how to eliminate the influence of the particle size of the sample, overcome the matrix effect of the co-existing elements, and quickly and accurately match the flow analysis is the focus of this law. To this end, the following measures have been taken: the actual sample as a standard sample; vibrating mill timing chronograph; using empirical coefficient method of coexistence of elements
