This invention is a comprehensive treatment method about recycling coal ash. The main sequence is following. Installing an automatic feeding device of flotation agent in origin. The agent is fed in quantification into ball miller. The coal ash and agent are mixed by rolling of the ball miller to save agitation energy. After agitation, the slurry is moved into flotation tank to separate useful carbon material and residual ash by the rise of bubbles in tank. The ferric oxide is picked up from ash by magnetic separation. At next step, the falling balls are picked up from ferric oxide by gravity. The falling balls can be components for rubber, plastic, paint, heat-insulator, fireproof material and cement. The residue can be stuff material. The carbon separated by rising bubble can be purified to the recycling carbon which can be fuel of power plant for energy saving.
