METHOD OF EXPLORATION OF BOLSHOPATOVSK NEAR-NORTH-POLE URAL COPPER- PLATINUM-NICKEL OXIDE-SULFIDE DEPOSIT

摘要

FIELD: mining industry. SUBSTANCE: first, intrusions from picrite, picrite-dolerite, and phengite-magnesite metasomatites are sampled for chemical analysis. From analytical data, one estimates ore-bearing capacity of intrusions. In addition, using microprobe analysis, samples are iteratively analyzed for contents of iron, nickel, copper, cobalt, platinum, palladium, sulfur, and following oxides: TiO₂, Al₂O₃, Fe₂O₃, MgO, MnO, NiO, Cr₂O₃, V₂O₃, ZnO, SiO₂, CaO, and PtO₂. Data obtained allow one to judge whether samples belong to platinum- bearing ores, while observation frequencies and characteristics of densities of valuable component s' distribution reflect degree of ore concentratibility and allow one to conclude whether explored areas are perspective. EFFECT: increased efficiency of early exploration. 2 tbl
