Problems solved by technology

[0003] At present, China's detection of mixed concentrates is based on the national standard GB / T3884-2011 "Chemical Analysis Methods of Copper Concentrates" drafted by Zhongtiaoshan Nonferrous Metals Group Co., Ltd. and Daye Nonferrous Design Research Institute Co., Ltd., in which each element The detection and analysis basically adopts single-element detection, and the joint measurement of major components and secondary components has not been realized. It takes 4 to 8 hours to complete the multi-element determination of a sample. The need for production control

Abstract

The invention discloses a novel detection and analysis method for components of mixed copper concentrates. The powder pressing method is used to make samples, and X-ray fluorescence spectrometry is used for detection and analysis. Unique instrument analysis parameters and matrix correction mode are adopted, among which Cu element is jointly calibrated by four correction modes of Fe Alpha empirical correction, S Beta empirical correction, Rh Compton correction and Zn spectral line overlap correction; S element The Alpha of CaO is empirically corrected, the Pb element is corrected by As's spectral line overlap, and the Sb element is corrected by Rh's Compton; realize the joint measurement of the main component and the secondary component in the mixed copper concentrate.

Description

technical field [0001] The invention relates to the field of metal element analysis in ore smelting production, in particular to an X-fluorescence joint detection analysis method for rapid analysis of multiple elements in mixed copper concentrates. Background technique [0002] The mixed copper concentrate is the furnace concentrate of the flash smelting process, which is prepared by mixing copper concentrate, blowing slag, and slag concentrate. The content of copper and iron is controlled at 20% to 25%, and the content of sulfur is at 25%. ~ 30%, silicon content is 5% ~ 10%, the ratio of mixed copper concentrate is one of the important indicators affecting the smelting furnace condition. Copper concentrate is made of copper-iron sulfide ore, and the contents of main elements and impurity elements are different between copper concentrates from different origins. The flash smelting process has great requirements on the ratio of the elements in the raw materials into the furn...
