The present invention relates to a floatation separation method of bottom ash which comprises the following steps: a step of sieve-separating the bottom ash; a step of mixing by inserting a collector and water into the sieve-separated bottom ash; a first separating step of separating the unburned carbon from the bottom ash by injecting air into the mixed bottom ash; a second separating step of separating a magnetic product from the bottom ash in which the unburned carbon has been separated; a third separating step of separating the water from the bottom ash in which the magnetic product has been separated; a step of drying the bottom ash from which the water has been separated. The present invention has an advantage of being used as an aggregate for construction and civil engineering by removing the unburned carbon.
