Disclosed is a production method of porous ceramic composite tiles. The production method includes steps of blending of raw materials of existing ceramic tiles, ball milling, spray drying, forming by dry pressing or extruding, drying again, decorating, high-temperature sintering, edge finishing and the like. Particularly, porous ceramic and non-porous ceramic are composited during forming and are subjected to one-step co-firing, blank firing shrining agents and foaming agents are contained in a raw material formula of the porous ceramic, and in the porous ceramic blank, the general ceramic tile blank accounts for 100 parts of the total weight, the blank firing shrinking agents account for 20-150 parts of the total weight, and the foaming agents account for 0.03-20 parts. As the porous ceramic layer and the non-porous ceramic layer are composited in the forming stage and then fired in a kiln at one step, energy consumption for one more firing can be reduced, and required porous composite ceramic products with unique and excellent performance can be produced.
