Abstract

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.

Description

Technical field: [0001] The invention relates to a building decoration material, in particular to a vitrified building decoration material prepared by using tailings of Anshan type iron mine and a preparation method thereof. Background technique: [0002] At present, my country's iron ore tailings stockpile is huge. There are more than 8,000 state-owned mines and more than 110,000 township collective mines in the country, with a cumulative stockpile of nearly 5 billion tons of tailings; 100 million tons, accounting for nearly 1 / 3 of the total tailings stockpiles, occupying a large amount of arable land and forests. The existence of iron tailings ponds has caused serious harm to the natural environment and seriously threatened the safety of the surrounding areas of tailings ponds. Anshan high-silicon iron ore is widely distributed in my country. Anshan high-silicon iron ore is strip-shaped lean iron ore, with an average iron content of about 30%. The main gangue minerals are ...
