Abstract
The results of mineralogical studies of the Besapantau deposit, typical of the Muruntau ore field (Central Kyzylkum), belonging to the low-sulfide gold-quartz geological-industrial type, are discussed. The most productive for gold is the early sulfide (pyrite-arsenopyrite) stage of mineralization. The minerals associated with gold and silver include pyrite, arsenopyrite, galena, fahlore, sulfoantimonides, and tellurides. Native gold varies in composition from electrum to very fine gold. Silver is present in the forms: native, gold-bearing, hessite, argentite, stephanite, pyrargyrite. Arsenopyrite can serve as an effective search indicator for gold in the conditions of forms, and also as the Central Kyzylkum, and the content of arsenic in ores can serve as a criterion for the degree of gold enrichment.
