Iron powder tailing treatment technology
The invention discloses an iron powder tailing treatment technology in the technical field of abandoned resource reutilization. The technology comprises the following steps that firstly, online magnetic separation is carried out on iron powder tailings before the iron powder tailings enter a tailing pool; then, enrichment materials obtained through magnetic separation are used as pelletizing materials, and the enrichment materials are returned to a blast furnace for iron making after ball pressing and sintering; and finally the tailings generated through magnetic separation are used for producing cement or mortar. The iron powder tailing treatment technology has the beneficial effects that magnetic separation is carried out on the iron powder tailings, the enrichment materials obtained through magnetic separation can be directly used for ball pressing, and the defects that the original tailing total-iron content is insufficient, viscosity is large, and scattering and even mixing are not easy are overcome; and in addition, the tailings generated in the production process can be used for producing cement or manufacturing mortar or other else, new tailings are not generated in the whole process, and resources are fully utilized.
