Example Embodiment

[0036] The present invention will be described in detail below with reference to the drawings and specific embodiments.

[0037] The invention provides a rapid combined measurement of Ni, Cu, Fe, S, CaO, MgO, SiO in flash smelting furnace slag 2 , Pb, Zn, As, Sb, Bi analysis method This method is carried out according to the following steps:

[0038] 1) Preparation of samples: First, sample grinding, put 100~150g of flash smelting slag into the grinding disc of sample preparation crusher and grind for 50-60s, and put the ground sample into the code sample bag; Second, sample compression, put the sample mold into the sample press, use a horn spoon to take out 4g-6g sample from the coded sample bag and put it into the sample mold, use industrial boric acid to rim and bottom the sample mold, and the press maintains the pressure Under the condition of 25-28T and holding time of 25-30s, make the sample into a sample with a diameter of 32mm, blow off the industrial boric acid powder adhe...

Abstract

The invention belongs to the technical field of chemical analysis detection, and specifically relates to an analysis method for rapid combined determination of Ni, Cu, Fe, S, CaO, MgO, SiO2, Pb, Zn, As, Sb and Bi in flash smelting furnace slag. The method comprises: preparing a sample sheet, preparing a standard sample sheet, preparing an instrument drift correction sample sheet, determining the instrument drift correction sample sheet, selecting a special matrix correction method, determining the sample sheet, and calculating the analysis result. According to the present invention, the powder tableting is used, the sample pretreatment process is rapid, the rapid determining is achieved, the multi-element determination of one sample can be completed within 10 min, the labor efficiency is high, the operation is simple, the instrument analysis parameters and the matrix correction mode are unique, the appropriate instrument analysis parameters and the unique correction mode are explored, the technical problem that the partial element standard curve regression is not linear is solved, the multi-element combined determination can be performed, and the combined determination of the main component and the secondary components can be achieved.

Description

technical field [0001] The invention belongs to the technical field of chemical analysis and detection, in particular to a rapid joint detection of Ni, Cu, Fe, S, CaO, MgO, SiO in flash smelting slag 2 , Pb, Zn, As, Sb, Bi analysis methods. Background technique [0002] Flash smelting slag is the alkaline calcium ferrite slag that is discharged from the powdery copper matte in the flash smelting furnace when it undergoes strong oxidation and vulcanization reactions to form blister copper. The main components are copper, iron, sulfur, calcium oxide, dioxide silicon etc. Flash smelting 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%. Moreover, the slag contains 20% copper oxide, which is oxidized in large quantities. The presence of copper greatly improves the ability of the slag to dissolve ferric oxide, which is of great significance to stabilizing the fu...
