| titleOfInvention | A beneficiation method for pre-roasting polymetallic associated iron tailings |
| abstract | The invention relates to a beneficiation method for pre-roasting polymetallic associated iron beneficiation tailings, belonging to the fields of mineral processing engineering and comprehensive resource recovery and utilization. A beneficiation method for pre-roasting multi-metal associated iron tailings is to carry out fluidized magnetization roasting of multi-metal associated iron tailings in a reducing atmosphere, and after roasting, the materials are subjected to weak magnetic separation to obtain weak magnetic separation ore and weak magnetic separation tailings; weak magnetic separation tailings are subjected to strong magnetic separation to obtain strong magnetic separation concentrates and strong magnetic separation tailings; rare earth flotation is performed on strong magnetic separation concentrates to obtain rare earth flotation concentrates and rare earth Flotation tailings; perform fluorite flotation on the strong magnetic separation tailings to obtain fluorite flotation concentrate and fluorite flotation tailings; mix rare earth flotation tailings and fluorite flotation tailings and concentrate them. The obtained concentrate is subjected to pickling and solid-liquid separation to obtain niobium-rich slag and pickling tailings. The invention finally obtains iron concentrate, fluorite concentrate, rare earth concentrate, and niobium-rich slag, thereby realizing comprehensive recovery and utilization of polymetallic minerals. |
