The invention relates to an architectural tile prepared by using Anshan-type iron ore tailings and a preparation method thereof. The architectural tile comprises iron ore tailings powder, blast furnace slag, borax, anhydrous BaCO3, magnesite, potassium feldspar, soda ash, TiO3, Sb2O3 and sulfur; and the preparation method comprises the following steps of: putting materials into a ball mill and carrying out mixed milling for a certain time to reach required granularity, adding water and blending into uniform thin paste, removing air bubbles on a vibration machine, removing upper water, pouring into a ceramic mold, vibrating on the vibration machine, then removing upper water, then putting the mold and the materials into a drying furnace together to be dried, putting into a sintering furnace to be roasted, discharging and demolding, cutting and shaping. The invention effectively utilizes resources, improves the environment and solves stacking problem of tailings. Compared with the prior art, the invention has high utilization ratio of iron tailings, low porosity, no waste gas, waste residues, waste water, noise and radioactive contamination in the preparation process, simple production process and easy operation. The cut and polished product has bright and clean surface and can substitute decorative materials, such as marble granite, and the like.
