Abstract: A vanadium-titanium magnetite deposit in Hami contains 12.07% Total Iron（TFe）， 5.99% Magnetic Iron（mFe），and 2.06% Titanium Dioxide（TiO₂），classifying it as an ultra-poor vanadi⁃ um-titanium magnetite ore. The ZKGC-type fine ore magnetic separator employs high-performance com⁃ posite rare-earth permanent magnetic materials and magnetic concentrating design，achieving a magnetic induction intensity of 560 mT on the drum surface with a maximum drum rotational speed of 6.2 m/s. Pre�concentration and tailings discarding tests were conducted on the ultra-fine crushed ore（via high-pressure grinding roll）using this novel dry magnetic separator. The results indicate that under the conditions of a feed particle size of P80=1.97 mm，a magnetic deflector angle of 11°，and a drum speed of 4.6 m/s，the sin⁃ gle-unit processing capacity reaches 279.82 t/ h，with a tailings discarding rate of 39.03%. The recovery rates of TFe，mFe，and TiO₂ in the pre-concentrate reached 71.35%，94.36%，and 71.02%，respective⁃ ly. The study demonstrates a significant reduction in mineral processing costs for ultra-poor vanadium-tita⁃ nium magnetite ores，providing a new technological pathway for the efficient utilization of similar resources.
