FIELD: mining engineering; processes.
SUBSTANCE: method involves roughing, cleaning and recleaner flotation. It provides withdrawal from flotation into the flotation concentrate of the froth of the roughing flotation that was obtained at the initial stage in the course of time of up to 25% of the total time of the roughing flotation. Besides, froth was obtained from the first cleaning flotation in the course of time of up to 50% of the time of the first cleaning flotation.
EFFECT: increased extraction of gold; reduced loss of gold with the flotation tails and enhanced economic efficiency of the gold extraction process owing to reduced consumption of reagents.
