Ceramsite fired by doping high-silicon iron tailings and preparation method thereof
The invention belongs to the field of comprehensive utilization of building materials and solid wastes, and particularly relates to a method for firing ceramsite by doping high silicon iron tailings and other solid wastes. The invention relates to ceramsite fired by doping high-silicon iron tailings, wherein the ceramsite is prepared from the following raw materials in parts by mass: 60-70 parts of high-silicon iron tailings, 10-15 parts of red mud, 5-12 parts of montmorillonite, 5-8 parts of pulverized coal and 5-10 parts of kitchen garbage. Various performance index values of the ceramsite prepared only in the north provided by the invention meet the standard requirements of GBT17431.1-2010 "Lightweight Aggregate and Test Method Thereof". According to the invention, in the ceramsite doped with the high-silicon iron tailings for firing, the high-silicon iron tailings are used as main raw materials; so that from the perspective of treatment of a large amount of solid waste, the problem that a large amount of tailings are accumulated is efficiently solved, solid waste resource utilization is achieved, waste is turned into wealth, and the influence of the solid waste such as the tailings on the environment is reduced. The technical scheme has certain ecological benefits and social benefits.
本发明属于建筑材料和固体废弃物综合利用领域，具体涉及一种掺入高硅铁尾矿等固体废物烧制陶粒的方法。一种掺入高硅铁尾矿烧制的陶粒，是由以下质量份的原料制成：高硅铁尾矿60‑70份、赤泥10‑15份、蒙脱石5‑12份、煤粉5‑8份，厨余垃圾5‑10份。通过本发明提供的只北方制备的陶粒各项性能指标值达到GBT17431.1‑2010《轻集料及其试验方法》的标准要求。本发明提供的掺入高硅铁尾矿烧制的陶粒利用高硅铁尾矿为主要原料，从大宗固体废弃物处理角度出发，不仅高效处理尾矿大量堆积问题，实现固废资源化利用，而且变废为宝，减少尾矿等固废对环境的影响，具有一定的生态效益和社会效益。
