Abstract

PURPOSE: To efficiently float a filler by adding a water-soluble trivalent metal ion salt to circulating water in a paper manufacture factory to adjust the pH of the circulating water, and then adding an anionic surfactant to the circulating wafer. CONSTITUTION: This method for floating a filler from circulating water in a paper manufacture factory comprises adding a water-soluble trivalent metal ion salt (preferably aluminum sulfate) to the circulating water preferably in an amount of 0.2-0.5 g/L to adjust the pH of the circulating water to 4.5-9, preferably 6-8, adding an anionic surfactant (preferably a 8-24C alkyl sulfate alkali metal salt) as a collector in an amount of 5-100 g/m<3> , preferably 20-40 g/m<3> , and then subjecting the mixture to the floatation and removal of the filler preferably at 45-60 deg.C.
