  • The recovery of ilmenite from vanadium titanomagnetite in Panxi area generally adopts “high-intensity magnetic flotation” as the principle process. This process technology is relatively mature and has certain adaptability, but the −38 μm fine ilmenite has not been effectively recovered, and a large number of −38 μm particles are directly discarded as slime, resulting in low total recovery rate and serious waste of resources. In order to improve the recovery rate of ilmenite, this paper explores the effect of magnetic separation and enrichment of three fine-grained samples of Panzhihua Iron and Steel Group Co., Ltd., Xiushui ore and Hongge ore. The test results show that the new ZQS high-gradient magnetic separator can efficiently recover ultrafine ilmenite; the grade and recovery rate of concentrate TiO2 are relatively high (86.80%, 82.26% and 77.78%, respectively, for the −0.038 to 0.019 mm grain grade). The magnetic separation technology is simple and shows a good perspective for industrial application.
