FIELD: beneficiation of minerals.
SUBSTANCE: invention can be used in the flotation of phosphate ores. The composition of the collecting mixture for flotation of phosphate ores includes sodium oleate and the product of phospholation of neonol AF-6 with phosphorus pentoxide, Phosphol-6. Sodium oleate and Phosphol-6 are used in the form of saponified solutions. The mixture additionally comprises a saponified solution of the product of phospholation of neonol AF-2 with phosphorus pentoxide, Phosphol-2, and a saponified solution of di-2-ethylhexyl ester of phosphoric acid, D2EHPA, in the following mass ratio of components, wt.%: D2EGFK 10.01-11.99; Phosphol-6 20.01-24.99; Phosphol-2 20.01-24.99; Sodium oleate is the rest.
EFFECT: increase in the degree of extraction of P2O5 into the flotation product.
