Mineralogical-geochemical peculiarities of gold mineralization of deposit “Shirotny”, South Uzbekistan

Abstract

As a result of the study of the mineralogical and geochemical features of gold mineralization at the Shirotny deposit, four natural ore types have been distinguished in terms of mineralogical composition, content of the main and associated components, mineralogical forms of gold finding. The main ore minerals are native gold, pyrite, scheelite, arsenopyrite, chalcopyrite, goethite, hydrogoethite, carbonaceous matter. According to the results of rational analyses, quantitative ratios of 5 forms of finding gold were revealed. The most widespread are 2 types: high-grade cyanated gold; gold finely disseminated in sulphides.
