FIELD: chemistry.
SUBSTANCE: invention relates to floatation of sulphide copper-molybdenum ore. The invention is based on using hydrazides of carboxylic acids of general formula 
, where R is a radical of aliphatic carboxylic acids CnH2n+1, as a reagent for floatation of sulphide copper-molybdenum ore. The said hydrazines essentially contain from 7 to 10 carbon atoms.
EFFECT: increased extraction of copper and molybdenum without using additional reagents and special foaming agents.
