Distribution platinum content in chromite and dunite type ores Nizhny Tagil massif (Middle Ural)

Abstract

The relevance of the work is due to the importance industrial meaning native and placer platinum deposits in basic-hiperbasic complexes. Methods of research included separation industrial type of ores for valuation quality platinum ore chute, use probabilistic-statistic, geometric-statistic and geostatistic model for description amplitude and frequency changeability in distribution platinum content in ore Nizhny Tagil massif. Result research. In chromite ores Nizhny Tagil massif platinum content vary in wide limits by predominance among theirs rich and ordinary ores and extremely uneven distribution platinum and other elements platinum group (palladium, rhodium, iridium, osmium, ruthenium) concentration in ores. In difference from ores chromite type in distribution platinum content in dunite ores massif in limits prospected Alexandrovsky area among industrial type ores prevail more low on quality poor and wretched ores by amplitude changeability platinum concentration in ores on data theirs ordinary sampling in prospect hole-from uneven to extremely, by gross sampling more deep mine working (half-pit and pit) – from even to very uneven. The largest frequency changeability in distribution platinum concentration in ores dunite type be distinguished ores widespread in north part Alexandrovsky area, differ and more low quality. Contemporary level development technology dressing platinum-bearing chromite and dunite type ores allowed consider theirs in quality perspective ores for joint processing.
