Abstract

Abstract

The TFe grade of a vanadium-titanium-iron concentrate in Panxi is 55.88%. The chemical composition of the main impurity elements in the sample include TiO₂, SiO₂, Al₂O₃, MgO and CaO, the proportion of impurities such as granular ilmenite and gangue minerals accountes for 14.26%. Ilmenite is mainly embedded in the titanium magnetite base in the form of guest crystals, and there are significant differences in impurity components and distribution characteristics between coarse and fine grained ferrotitanium vanadium concentrates. Three comparative experiments were conducted on the vanadium titanium iron concentrate, including "preliminary classification - coarse particle regrinding magnetic separation", "preliminary classification - coarse particle regrinding magnetic separation - fine particle magnetic separation", and "deep magnetic separation - classification - coarse particle regrinding magnetic separation". Meanwhile, magnetic separation equipment comparative tests were cared out by using electromagnetic wet drum magnetic separator, high-frequency harmonic magnetic separator and magnetic separation column. In addition, a comparative analysis was conducted on the main chemical and mineral components of the iron concentrate before and after upgrading. Research results show that using an electromagnetic wet drum magnetic separator as the sorting equipment, the process of "preliminary grading (0.074mm) - coarse particle regrinding (−0.074 mm accounting for 96.50%) magnetic separation - direct magnetic separation with fine particle" has the best quality improvement effect. After the quality improvement, the TFe grade of the vanadium titanium iron concentrate increases by 3.36 percentage points, the proportion of impurities decreases by 6.92 percentage points, and the TFe/TiO₂ increases by 3.44 percentage points.
