成果简介	NOVELTY - Invention relates to hydrometallurgy of non-ferrous and precious metals and can be used in processing of carbonaceous gold-containing concentrates having double process resistance due to fine dissemination of gold in the sulphide matrix and the presence of a natural carbonaceous substance, which is sorption-active with respect to the gold-cyanide complex. Method involves preliminary pulping of a carbonaceous gold-containing concentrate in an aqueous solution of a surfactant and its subsequent nitric acid leaching at concentration of nitric acid of 5 mol/dm3 at atmospheric pressure, temperature of 85±10 °C and duration of 90 minutes, filtration, washing, drying and cyanidation of cake. USE - Metallurgy. ADVANTAGE - Method increases extraction of gold and reduces consumption of nitric acid. 2 cl, 2 dwg, 6 ex
