INCIDENTAL EXTRACTION OF RARE MICROELEMENTS DURING THE SYSTEMATIC PROCESSING OF SULFIDE COPPER ORES

摘要

The incidental concentration of valuable components that takes place during the processing of sulfi.de copper ore in Kazakhstan is accompanied by the formation of a semifinished product which contains large amounts of osmium, rhenium, and selenium. The article identifies products with high concentrations of rare micro-components, describes methods of extracting them, and discusses aspects of the technological behavior of rhenium, radiogenic osmium, and selenium.
