At present, our country comprehensive management and utilization of tailings residues chaliapin remained in a way, content and low value-added products. Using tailing residues glass-ceramics, preparation for the comprehensive utilization of tailings opened a new approach, significant environmental benefits, social benefits and economic benefits. Crystallite glass or crystal glass ceramic and glass, is a new kind of inorganic non-metallic material, it has high mechanical strength, excellent insulating performance, dielectric loss less stable, dielectric constant coefficient, in a great extent, corrosion-resistant, wear-resisting, good thermal stability, high temperature performance, is a kind of good performance of new materials. This topic experiment with rare choose tailings and fly ash as the main raw material, adding a bit of grit and potassium nitrate, and other chemical raw materials, CaO-Al2O3-SiO2 system design, crystallite glass was based glass component of crystalling phase mainly pyroxene, crystallite glass and when tailing with fly ash, different with different proportion of added, dosage of glass-ceramics preparation phase, morphology and properties, finally discovers the effect of utilization
