Method for comprehensively utilizing flotation tailings and red mud

The invention relates to a method for comprehensively utilizing flotation tailings and red mud, and belongs to the technical field of solid waste resource recycling. The method comprises the steps that the flotation tailings and the red mud are mixed, and a mixed material is obtained; roasting the mixed material to obtain a roasted material; separating the roasted substance to obtain iron minerals and aluminum-silicon slag; wherein FeS2 is contained in the flotation tailings. According to the collaborative comprehensive utilization method for the flotation tailings and the red mud, the influence of stacking of the flotation tailings and the red mud on the environment is avoided, collaborative recovery of iron minerals in the flotation tailings and the red mud is achieved, and residual aluminum-silicon slag can be returned to an aluminum oxide process or used for building materials. 本申请涉及一种综合利用浮选尾矿和赤泥的方法，属于固体废物资源回收技术领域，所述方法包括：将浮选尾矿和赤泥进行混合，得到混合物料；将所述混合物料进行焙烧，得到焙烧物；将所述焙烧物进行分离，得到铁矿物和铝硅渣；其中，所述浮选尾矿中含有FeS2。本申请提供了一种浮
