PROBLEM TO BE SOLVED: To provide a method and an apparatus for promoting the surfacing of micro bubbles when suspended matter in a suspension is subjected to flotation by using micro bubbles. SOLUTION: The flotation of the suspended matter is promoted by dispersing micro bubbles having the diameter of 1-100μm in the suspension by using a micro bubble generator 4 to stick the suspended matter to the surfaces of the dispersed micro bubbles and irradiating the micro bubble-dispersed suspension with the ultrasonic wave, which is emitted from an ultrasonic transmitter 3 and has the frequency of 20 kHz to 1 MHz, to promote the agglomeration among micro bubbles.
