FIELD: selective floatation of apatite ores under condition of water circulation. SUBSTANCE: proposed method employs polyethyleneglycol esters of the following common formula: 
, where R is alkyl radical at number of carbon atoms equal to 9-isononyl; n is number of oxyethyl groups from 6 to 12 inclusive which are used as organic regulator for floatation of apatite ores. Proposed method includes successive treatment of pulp by caustic soda, water glass, organic regulator, conditioning and subsequent floatation by oxyhydride collecting agent. EFFECT: improved service and economic parameters; enhanced ecological safety. 3 dwg, 1 tbl
