| titleOfInvention | Full-scale utilization method for reducing, roasting, separating and recovering iron and silicon-aluminum synchronous activated red mud |
| abstract | The invention discloses a full-scale utilization method of red mud for synchronous activation of reduction roasting separation recovery iron and silicon-aluminum, belonging to the field of solid waste treatment and resource utilization. Drying the red mud, grinding the dried red mud into powder, adding a carbon-based reducing agent, reducing and roasting, wherein ferric oxide in the red mud is reduced into ferroferric oxide, ferrous oxide and an iron simple substance, and meanwhile, silicon-aluminum elements in the red mud are activated; mixing the reduction roasting intermediate product with water, performing magnetic separation by using a magnetic separator to obtain an iron concentrate product, and filtering the magnetic separation suspension to obtain magnetic separation residues; mixing the magnetic separation residue with fly ash, adding sodium hydroxide, potassium hydroxide or water glass, and adding water to obtain a clean slurry; and pouring the clean slurry into a mold, heating and curing under a sealed condition, taking out the mold, demolding, and performing standard curing to obtain the geopolymer. The invention realizes the resource recovery and full-scale utilization of the red mud, and has the characteristics of high utilization rate of solid waste, good mechanical property of products and low production cost. |
