Method for processing vanadium titano-magnetite

A method for processing vanadium titano-magnetite relates to a method for preparing iron powder and ilmenite concentrate from vanadium titano-magnetite through fluidized bed roasting and magnetic separation. The method is characterized by comprising the following steps in sequence: (1) crushing and grinding the raw ore of vanadium titano-magnetite; (2) drying and pre-heating the powdery material; (3) performing reducing roasting in a heat-ore fluidized bed furnace; (4) carrying out ball milling after calcining and water quenching; and (5) performing magnetic separation to obtain the iron powder and the ilmenite concentrate. The method provided by the invention employs two sections of furnace treatment: a drying preheating section and a reducing roasting section; and compared with a traditional method, the method is short in process flow and avoids briquetting, or pelletizing processing and roasting process sintering of the raw ore, and prevents the raw ore from being attached to the wall; the operation stability is enhanced, and simultaneously, metal enrichment ratio is increased; moreover, the select-out ratios of materials in the whole flow are as follows: the select-out ratio of concentrate iron is 90-96%, while the select-out ratio of vanadium is 55% and the select-out ratio of tailing titanium is 95%.
