FIELD: mining engineering.
SUBSTANCE: method involves conditioning gold-carbonaceous ores with depressant as a polycondensation product of sodium naphthalenesulfonate and formaldehyde. After conditioning ores to produce the gold-containing flotation concentrate, copper sulfate is sequentially introduced as an activator, at the end of contact time butyl xanthate as a collector, and then methyl isobutylcarbinol as a frothing reagent.
EFFECT: flotation concentration of gold-carbonaceous ores with deactivation of sorption capacity of carbon presented is provided.
