Building ceramic tile prepared from fine-grained iron tailing powder and preparation method of building ceramic tile

The invention discloses a building ceramic tile prepared from fine-grained iron tailing powder and a preparation method of the building ceramic tile, and belongs to the technical field of solid waste recycling and building ceramic tiles. The preparation method comprises the following steps: taking fine-grained iron tailing powder as a base material, adding a plasticizer, a sintering aid, a coloring agent and a defoaming agent as auxiliary materials, then adding an adhesive, uniformly mixing, granulating to obtain a granulated material of the building ceramic tile, then adopting a certain forming process to obtain a green body of the building ceramic tile, and sintering the green body of the building ceramic tile to obtain a finished product of the building ceramic tile. The building ceramic prepared by the method comprises 50-90% of fine-grained iron tailing powder, 1-15% of a plasticizer, 5-35% of a sintering aid, 0.1-5% of a coloring agent and 0.1-5% of a defoaming agent, wherein the total percentage is 100
