Method for preparing ceramic material through low-temperature sintering of magnetite tailing fine silt, molybdenum ore tailing fine silt and fluorite ore tailing fine silt in Synergistic Region
The invention relates to a method for preparing a ceramic material through low-temperature sintering of fine magnetite tailings in the commitment region in cooperation with fine molybdenum ore tailings and fine fluorite tailings, and relates to the technical field of comprehensive utilization of solid waste and ceramic materials. According to the preparation method, fine silt of magnetite tailings, molybdenum ore tailings and fluorite ore tailings in the Chide region of Hebei Province is taken as a raw material, low-melting-point minerals (potassium feldspar and albite) and a sintering aid (water glass) are added, and the tailings-based low-temperature sintered ceramic material is prepared through the processes of drying, screening, ball milling, dry pressing, heat treatment and the like. Based on the common problems of large component difference, low quality and high material utilization difficulty of the fine tailings, the ceramic material with low sintering temperature and excellent performance is prepared by adding the additive. The method has the advantages of being low in cost, green, clean, simple and feasible in process and the like, and has important significance for improving the comprehensive utilization rate of resources, reducing environmental pollution and comprehensively utilizing typical tailings as resources.
本发明涉及一种利用承德地区磁铁矿尾矿细泥协同钼矿尾矿细泥和萤石矿尾矿细泥低温烧结制备陶瓷材料的方法，涉及固体废弃物综合利用、陶瓷材料技术领域。本发明以河北省承德地区磁铁矿尾矿、钼矿尾矿和萤石矿尾矿的细泥为原料，添加低熔点矿物(钾长石和钠长石)和烧结助剂(水玻璃)，通过干燥、筛分、球磨、干压成型以及热处理等工艺制备尾矿基低温烧成陶瓷材料。本发明基于尾矿细泥成分差异大、品质低、材料化利用难度大的共性问题，通过加入外加剂，制备得到具有烧结温度低且性能优良的陶瓷材料。本发明方法具有成本低廉、绿色清洁且工艺简单可行等优点，为提高资源综合利用率、减少环境污染以及对典型尾矿的资源化综合利用具有重要意义。
