摘要

FIELD: metallurgy.;SUBSTANCE: invention relates to the metallurgy of non-ferrous and precious metals, in particular, the processing of refractory carbonaceous ores containing gold and silver. The method includes flotation concentration of crushed ore and subsequent sorption cyanidation of the obtained flotation concentrate. Flotation concentration is carried out using a composite organic carbon depressant, which is introduced into the ore pulp together with flotation reagents, containing components in the ratio: 24-34% amylose, 62-72% amylopectin and 4-6% lignin. The flotation concentrate is treated before sorption cyanidation with a mixture of kerosene and nigrosine.;EFFECT: invention provides an increase in gold recovery when processing carbonaceous gold-bearing ores with different levels of sorption activity, type and concentration of carbonaceous matter.;1 cl, 1 dwg, 2 tbl, 3 ex
