Beneficiation of a Vanadium-titanium Magnetite in Panxi

Taking a vanadium-titanium magnetite in Panxi as the research object,a beneficiation test was carried out for the titanium magnetite and ilmenite.The titanium magnetite was recovered by the process of pre-throwing tailings followed by two-stage grinding and magnetic separation,and the iron concentrate with a yield of 19.78%,a TFe grade of 55.34% and a TFe recovery rate of 51.27% can be obtained finally.The tailings of iron beneficiation contain a large amount of ilmenite,and the TiO₂ grade can be increased from 9.38% to 21.58% by two stages of iron removal and strong magnetic processes.The flotation process was used to further improve the TiO₂ grade. Through the process of floating sulfur-desliming-one rough and three concentration,qualified titanium concentrate with a yield of 9.53%,a TiO₂ grade of 47.45%,and a TiO₂ recovery rate of 47.87% can be obtained.
