| description | The invention discloses a process for recovering ferroniobium rare earth from refractory ores based on a suspended state ore phase conversion method. The process comprises the following steps: (1) carrying out suspended state ore phase conversion on raw ores; (2) fine grinding: grinding the suspension state mineral phase conversion product; (3) low-intensity magnetic separation: carrying out wet-type low-intensity magnetic separation on the fine grinding product; (4) rare earth flotation: carrying out rare earth flotation by taking low-intensity magnetic separation tailings as raw materials; (5) pickling and stirring: pickling the rare earth flotation tailings and continuously stirring; (6) washing and concentrating: washing and concentrating the acid-washed ore sample; and (7) niobium flotation is conducted, specifically, niobium flotation is conducted on the concentrated ore pulp, and niobium concentrate and niobium tailings are obtained after flotation. According to the method, weak magnetic iron minerals |
