Abstract

The invention belongs to the technical field of chemical analyzing and detection and particularly relates to an analyzing method for fast simultaneously detecting Ni, Cu, Fe, S, CaO, MgO, SiO2, Pb, Zn, As, Sb and Bi in flash-converting slag. The method includes: preparing a sample piece, preparing a standard sample piece, preparing an instrument-drift-corrected sample piece, detecting the instrument-drift-corrected sample piece, selecting a special matrix correcting method, and calculating sample piece measuring and analyzing results. The method has the advantages that powder piece compressing is used, a sample preprocessing process is fast, fast detecting is achieved, multi-element detecting of one sample can be completed in 10 minutes, high labor efficiency and simple operation are achieved, unique instrument analyzing parameters and the unique matrix correcting mode are adopted, the appropriate instrument analyzing parameters and the unique correcting mode are explored, the technical problem that part of element standard curvilinear regression is nonlinear is solved, multi-element simultaneous detecting can be performed, and simultaneous detecting of main components and secondary components can be achieved.

Description

technical field [0001] The invention belongs to the technical field of chemical analysis and detection, and in particular relates to an analysis method for rapid joint detection of Ni, Cu, Fe, S, CaO, MgO, SiO2, Pb, Zn, As, Sb and Bi in flash blowing slag. Background technique [0002] Flash converting slag is the alkaline calcium ferrite type slag that is discharged from the powdered copper matte in the flash converting furnace when blister copper is formed through strong oxidation and vulcanization reaction. The main components are copper, iron, sulfur, calcium oxide, Silica, etc. Flash blowing uses calcium ferrite slag. Compared with iron silicate slag, calcium ferrite slag has a much stronger ability to dissolve iron tetroxide, which can reach more than 20%, and the slag contains 20% copper oxide. The presence of copper oxide greatly improves the ability of slag to dissolve ferric oxide, which is of great significance to stabilizing furnace conditions. [0003] The qua...
