concentration of minerals; floatation of phosphate niobium ores, as well as flotation of apatite and phosphate ores. SUBSTANCE: proposed method includes conditioning of pulp with soda, water glass, commercial lignin sulfonates, introducing collecting agent containing acetylated amino acids and separating phosphate minerals into foam product. Used as commercial lignin sulfonates is product obtained through oxidation of starting commercial lignin sulfonates with ozone in the amount of 0.075 to 0.1 kg/t. EFFECT: enhanced erosion parameters. 2 cl, 2 tbl, 1 ex
