On accelerated spectral quantitative determination of copper in pyrite ores

Abstract

Thanks to the creation of high-quality domestic equipment for studying minerals and ores, spectral analysis methods are becoming increasingly important both in studying the material composition of deposits, host rocks, mineralization zones, etc., and in quantitatively assessing the content of ore components in them. Spectral analysis is of particular value in field conditions, increasing the efficiency of geological exploration and allowing a preliminary assessment of the objects under study. Experimental studies conducted by us on the material of studying copper pyrite ores allowed us to develop a method for rapid quantitative spectral determination of copper in field conditions without the use of complex additional equipment. Methods of quantitative spectral analysis are based on an unambiguous relationship between the intensity of the spectral lines of elements and the concentration of these elements in the substance under study. This relationship is established by comparing the spectra of samples and standards visually or with a microphotometer by measuring the blackening of the spectral lines.
