INVESTIGATING THE EXTRACTION OF NOBLE METALS CONTAINED IN CARBON ORES BY THE METALLOTHERMIC METHOD

Abstract

An investigation of the extraction process of noble metals contained in carbon ores is carried out by the metallothermic method. The results of the research show when testing carbon ores and the products of their enrichment by the technology of self-propagating high-temperature synthesis, noble metals contained in the raw material transfer to chemically complex metal compounds. It is shown that, besides gold and silver, different platinum metals are accumulated in these products, whose discovery is basically possible by decomposition with acids. By summing up the research data, we can state that the overall content of noble metals in the concentrates is 20 g/t.
