Problems solved by technology

[0004] The status quo of national standards: The detection and analysis of each element in the nonferrous metal industry standard "Matte" YS / T990-2014 of the People's Republic of China basically adopts single element detection, and the joint measurement of the main component and the secondary component has not been realized. Completed The multi-element determination of a sample takes 4-8 hours, and the detection and analysis time and detection efficiency are obviously insufficient

Embodiment Construction

[0029] The present invention will be further described below in conjunction with specific embodiments.

[0030] A rapid joint measurement of Ni, Cu, Fe, S, Pb, Zn, As, Sb, Bi, SiO in matte 2 The analysis method includes the following steps:

[0031] Step 1. Grinding of the sample to be tested: Take 100-150g of the matte sample to be tested and put it into a grinding disc, grind it in a sample-making pulverizer for 50-60s, control the particle size to be greater than 120 mesh, and pack it into a bag.

[0032] Step 2: Compression of the sample to be tested: put a circular funnel-shaped sample mold with a diameter of 32 mm into the pressing machine, use a horn spoon to take 4-6 g of the matte sample to be tested and put it into the mold, and use 10-6 g of industrial boric acid. 20g rimmed bottom, under the conditions of pressure 20-25T and holding time 25-30s, a sample piece to be tested with a diameter of 32mm is made on a hydraulic sample making machine with a range of 0-50T, ...

Abstract

The invention discloses an analyzing method for rapid and simultaneous determination of Ni, Cu, Fe, S, Pb, Zn, As, Sb, Bi and SiO2 in copper matte. The method includes the steps of grinding a to-be-determined sample; tabletting the to-be-determined sample; preparing a standard sample tablet; preparing an instrument drift correction sample tablet; drawing a working curve; performing special matrix correction; performing instrument drift correction; determining the to-be-determined sample tablet; computing an analyzing result. The analyzing method has the advantages that rapid determination of elements or components of the Ni, the Cu, the Fe, the S, the Pb, the Zn, the As, the Sb, the Bi and the SiO2 in the copper matte is achieved, and simultaneous multi-element or multi-component determination of one sample can be completed within ten minutes, so that the defects of single-element and single-method determination of traditional methods are overcome, and simultaneous determination of major components and minor components is achieved; compared with the national standard, the analyzing method is capable of saving more than four hours of sample analyzing time, rapid in detection and analysis, high in labor efficiency and simple and convenient to operate and has promising application prospect and high practical value.

Description

technical field [0001] The invention belongs to the field of chemical analysis and detection of matte, in particular to a rapid joint measurement of Ni, Cu, Fe, S, Pb, Zn, As, Sb, Bi, SiO in matte 2 method of analysis. Background technique [0002] According to the national standard GB / T11086-1989 "Terminology of Copper and Copper Alloys", unrefined copper includes matte, which is also called copper matte. It is mainly composed of cuprous sulfide and ferrous sulfide melting each other, and also a small amount of other metal sulfides (such as Ni 3 S 2 , PbS, ZnS, etc.), iron oxide (FeO, Fe 3 O 4 ), precious metals (Au, Ag), platinum group metals and trace gangue components. Its copper content is between 20% and 70%, and its sulfur content is between 15% and 25%. Matte is the main product of the smelting furnace and an important raw material for the production of blister copper in the blowing furnace. According to the imported raw materials and the product quality re...
