Foaming ceramic material based on low-silicon high-calcium iron tailings and preparation method thereof
The invention provides a foamed ceramic material based on low-silicon high-calcium iron tailings, the foamed ceramic material comprises the following raw materials by weight: 20-60 wt% of low-silicon high-calcium iron tailings, 24-60 wt% of a lean material, 15-35 wt% of a plastic material, and 0.1-0.5 wt% of a foaming agent, and the invention also provides a preparation method of the foamed ceramic material, and the preparation method comprises the following steps: S1, finely grinding the raw materials, and then carrying out mechanical dry mixing; s2, adding water, dispersing and uniformly mixing to obtain slurry, and drying and forming the slurry to obtain a blank; and S3, sintering the blank, cooling, and cutting to obtain the foamed ceramic material. According to the invention, the high-calcium iron tailings are used as a flux material, so that fluxing materials such as feldspar and the like can be completely replaced to reduce the production cost and reduce the consumption of a foaming agent, the firing temperature can be greatly reduced, and other solid waste materials are matched, so that the problems of resource utilization of bulk mining wastes and high value of products are solved.
本发明提供了一种基于低硅高钙型铁尾矿的发泡陶瓷材料，原料按重量百分比计，包括低硅高钙型铁尾矿20～60wt％，瘠性物料24～60wt％，塑性物料15～35wt％，发泡剂0.1～0.5wt％，还提供了该发泡陶瓷材料的制备方法，包括步骤：S1、将原料细磨后进行机械干混；S2、加入水分散混匀得到浆料，浆料干燥成型得到胚体；S3、胚体进行烧结，冷却后进行切割，得到发泡陶瓷材料。本发明利用高钙型铁尾矿作为熔剂材料使用，既能完全替代长石等助熔材料以降低生产成本，减少发泡剂的用量，且能大幅度降低烧成温度，并配合其他固废材料，得以解决大宗矿业废物资源利用与产品高值化问题。
