Development method for determining copper smelting slag multi-element standard sample through X-ray fluorescence spectrometry

Abstract

The invention discloses a development method for determining a copper smelting slag multi-element standard sample through X-ray fluorescence spectrometry. The development method comprises the following steps: preparing a standard sample; examining uniformity; determining analysis of standard value on components in the standard sample; performing the analysis of standard value; performing the analysis on data summarization, processing and performing the analysis on the result precision; performing inter-laboratory comparison tests; performing standard value determination; and examining a linearrelation of representative elements in the standard sample through a X-ray fluorescence spectrometer. A development method of the standard sample can satisfy the requirement of the standard sample bythe X-ray fluorescence spectrometer, and the standard sample and a detected sample are prepared to a similar and reproducible state; and the sample and the standard sample have consistent physical property and approximate chemical composition as possible. The method can be used for preparing the appropriate standard sample used for an X-ray fluorescence spectral analysis by the slag obtained by smelting enterprises according to self attribute of raw materials, and has high economic value and strong practicality.

Description

technical field [0001] The invention belongs to nonferrous metallurgy analysis technology, in particular to a method for developing standard samples of multi-elements in copper smelting slag by X-ray fluorescence spectrometry. Background technique [0002] The smelting slag is an important product in the copper smelting process. The control and optimization of the smelting process requires an accurate understanding of the viscosity of the slag. It not only affects the mass and heat transfer in the slag, but also affects the loss of valuable elements in the slag and the smelting furnace. life. And Fe, SiO in the slag 2 , CaO, MgO, Al 2 o 3 The amount of content directly affects the result of slag viscosity, therefore, timely and accurate determination of Cu, Fe, SiO in slag 2 , CaO, MgO, Al 2 o 3 The content of other elements has important practical significance for guiding production. At present, traditional chemical analysis methods, atomic absorption, and ICP-AES ar...
