Abstract:

Purpose. To study interrelations between main ore minerals from alkaline metasomatic zones which causes abnormal concentration of noble metal mineralization within the Severo-Belozerskoye deposit in the Middle Pridneprovie area of the Ukranian Shield.

Methodology. The petrography and mineragraphy methods were used for solving the research tasks. The half-quantity spectral analysis of gold, silver, platinum group elements in abnormal interval of carbonate-metasomatic zones within the Severo-Belozerskoye deposit have been carried out. The tests on enrichment have been carried out in Krivorozhskiy Technical University.

Findings. The petrographical composition of ore-bearing metasomatites from alkaline metasomatic zones has been studied. Matter composition and the stages of ore mineralization formation have been established; relations of main ore minerals from alkaline metasomatic zones have been studied. We concluded that ferruginous quartzites from the Severo-Belozerskoye deposit have complex composition and contain noble metal mineralization. The complex mineralization of noble metals related to the carbonate-alkaline zone. The majority of anomalies concentrate within central part of the metasomatic zone. The sum content of noble metal mineralization changes from 1634 mg/t. to 1298 мg/t. Ore mineralization of alkaline metasomatic zones is represented by pyrite, pyrrhotite, hematite, magnetite, аrsenopyrite. Probable mineral, which concentrates noble metal mineralization, is pyrite, pyrrhotite, chalcopyrite. Close connection between the complex of the noble metals and sulfide concentrate has been established in the process of technological probe enrichment. Special value of the carried out technological tests consists in complex composition of the obtained concentrates. The content of gold and silver meets the requirements of pyrometallurgy industry.

Originality. Conditions of the mineralization localization, the mineral composition and stages of ore mineralization formation were characterized for the first time. Relations between the main ore minerals from alkali metasomatic zones and probable minerals-concentrators of precious metals in ferruginous quartzite of the Severo-Belozerskoye deposit have been determined.

Practical value. Precambrian ferruginous quartzites are the main source of production of high-quality iron ores. Annual ore extraction rate reaches 45 million tons, and production of magnetite concentrates reaches 10–13 million tons. With such volumes of ore production the problem of extraction of the associated valuable components: gold, silver, platinum, palladium, rhodium containing in ferruginous quartzites of the Severo-Belozerskoye deposit is very urgent.
