FIELD: metallurgy.
SUBSTANCE: invention relates to processing of carbonaceous gold-containing ores. Processing of carbonaceous gold-containing ores involves processing of floatation pulp with a reagent based on a product of organic synthesis on a naphthalene formaldehyde base. Reagent contains 10–15 wt% of lignin or lignosulphonate. Thereafter, the collector and the foaming agent are treated.
EFFECT: method with the reagent used increases the degree of gold extraction due to depression of slime and minerals of gangue with reduction of weight fraction of organic carbon in the obtained floatation concentrate.
