Abstract: To improve the understanding of preparing porcelain bricks with iron ore tailings and promote the quality of recycling economy and the utilization of mineral resource，the research statures of porcelain vitreons bricks made from iron ore tailings in our country was sumarized,the situation and the key techniques of preparing porcelain vitreous bricks with domestic iron ore tailings were summarized.Based on summarizing the key technical difficulties in the preparation above，the effect of common ingredient of iron tailings on preparing the porcelain vitreous bricks as building materials and the related countermeasures were analyzed.The previous research showed that it was entirely feasible to prepare porcelain tiles with iron ore tailings by adjusting the process and formula,but its instability in component is the key factor that limited the large-scale production of porcelain vitreous bricks with iron ore tailings.Although some calcium minerals in iron ore tailings could increase the strength of porcelain vitreous bricks and iron-bearing minerals could make bricks colorful，the minerals such as Ca，Fe and S，micas in iron ore tailings would influence the firing process and the strength of the bricks in different ways，which should be carefully studied and solved.
