Method for co-processing and utilizing red mud and steel dust

The invention provides a method for co-processing and utilizing red mud and steel dust, and relates to the technical field of red mud. The method for co-processing and utilizing the red mud and the steel dust specifically comprises the following steps: S1, drying and fine grinding; s2, preparing materials into balls; s3, roasting, grinding and selecting; and S4, carrying out hydrothermal reaction separation. The invention provides a method for co-processing and utilizing red mud and steel dust, which sequentially comprises the following steps of: volatilizing out zinc, magnetically separating to obtain iron powder, and carrying out hydrothermal reaction to separate out a tobermorite product and a sodium aluminate solution, a new scheme is provided for efficient separation and recovery of iron, zinc, aluminum, silicon, sodium and other valuable elements in the red mud and the steel dust, and co-treatment and value-added utilization of the red mud and the iron, zinc, aluminum, silicon, sodium and other valuable
