Method for detecting copper ores and copper-containing materials based on infrared spectroscopy

Abstract

The invention relates to the technical field of ore detection and particularly relates to a method for detecting copper ores and copper-containing materials based on an infrared spectroscopy. The method comprises the following steps: (S1) fetching 0.5-1 part of a to-be-detected sample and 140-460 parts of potassium bromide powder in parts by weight, grinding until the particle sizes of sample particles are smaller than 2.5 microns, and uniformly mixing; (S2) carrying out tabletting on the mixed to-be-detected sample, putting the to-be-detected sample into an infrared spectrometer, and carrying out detection, so as to obtain a spectrogram; and (S3) carrying out base line correction, smoothening and standard peak analysis on the spectrogram, indexing the sample spectrogram in a spectrogram database, and primarily determining main compounds in the sample by combining with a characteristic absorption peak. According to the method provided by the invention, imported copper ores and copper-containing materials are identified through the equipment, and the infrared identification technique is applied in the usable smelting slag in the preliminary stage in the mineral product.

Description

technical field [0001] The invention relates to the technical field of ore detection, in particular to a detection method for detecting copper ore and copper-containing materials based on infrared spectroscopy. Background technique [0002] In recent years, with the implementation of the "One Belt, One Road" initiative, the types and quantities of mineral products imported from Xinjiang ports have continued to increase. The Alashankou Port in the West Bridgehead often uses "copper matte" (combination of non-ferrous heavy metal sulfides and iron sulfides) The body is called molten matte, which is an important intermediate product of sulphide concentrate pyrometallurgy of copper, nickel and other metals. The matte obtained in the process of copper smelting is called copper matte, commonly known as matte) imported from Kazakhstan in the name of production Sintered ore or smelting slag from primary smelting or rough processing of copper. This commodity has high copper content, w...

Problems solved by technology

[0004] In addition, the existing quantitative analysis methods for copper-containing materials and copper concentrates can only analyze the content of each element in the commodity with a confirmed product name

For the identification method of copper ore and copper-containing materials, X-ray fluorescence spectrometer and X-ray diffractometer can be used together for identification. Some laboratories cannot carry out identification work when only one of the equipment is used.
