Geochemical peculiarities of accompanying elements Filizchai pyrite-polymetallic deposit (southern slope of the Greater Caucasus)

Abstract

The article considers the distribution of accompanying elements (cadmium, indium, selenium, tellurium, bismuth, etc.) in pyrite-polymetallic ores of the Filizchay deposit. It was found that there is a high correlation between the concentrations of cadmium, zinc and lead (r=+0.790 and r=+0.616). The relationship between the contents of cadmium and copper is negative (r=-0.414). Indium - correlated with zinc and cadmium. In the Filizchaya ore deposit, a relatively high amount of indium is present in the upper depth horizons and the western flank of the deposit. The mineralconcentrator of the element is zinc sulfide. A high correlation was established between antimony and arsenic (r=+0.663). There is a significant correlation coefficient of these elements with zinc, lead, silver, bismuth and cadmium. In connection with the regular arrangement of natural types of ores in the composition of a single ore deposit of the deposit, a regular change in the concentrations of these elements is established. In general, there is a vertical and horizontal zonality in the distribution of harmful impurities in the ore deposit. It has been established that the content of antimony and arsenic gradually decreases from the upper to deep horizons. The concentration of antimony and arsenic decreases from the western flank to the east, and the content of mercury from the western flank to the central part increases slightly, and on the eastern flank its concentration decreases to a minimum, selenium is more concentrated from the central part of the ore deposit of the deposit. It was revealed that the formation of the Filizchay deposit was accompanied by a zonal distribution of chemical elements, consistent with the general scheme of mineralogical zoning.
