Iron tailing ceramsite and preparation method thereof
The invention relates to the field of comprehensive utilization of iron tailing resources, and mainly relates to iron tailing ceramsite and a preparation method thereof. The method comprises the following steps: uniformly stirring raw materials according to a given mass percentage, adding water, mixing to obtain a mixed material, putting the mixed material into a disc pelletizer to prepare an iron tailing ceramsite spherical material, drying the obtained ceramsite, cooling to room temperature, putting into an industrial microwave oven, and carrying out microwave heating treatment to obtain the iron tailing ceramsite. And cooling to obtain the iron tailing spherical ceramsite with good grain composition. According to the method, the solid waste iron tailings can be fully utilized, the additional value of the solid waste can be greatly increased, resource recycling of the solid waste is achieved, site resources occupied by landfill are reduced, and meanwhile contribution is made to environmental protection.
本发明涉及铁尾矿资源综合利用领域，主要涉及一种铁尾矿陶粒及其制备方法。本发明包括以下步骤：将原料按既定质量百分比搅拌均匀，加水混合得到混合物料，将混合料放入圆盘造球机，制得铁尾矿陶粒球形料，将得到的陶粒烘干并冷却至室温后，放入工业微波炉中进行微波加热处理，冷却后得到颗粒级配良好的铁尾矿球形陶粒。本发明不仅可以充分利用固体废弃物铁尾矿，而且能够大幅度提高固体废弃物的附加值，实现固体废弃物的资源化循环利用，减少因填埋占用的场地资源，同时为环境保护做出贡献。
