| 摘 要： | 红格南矿区钒钛磁铁矿多为橄辉岩型矿石，其矿物组成种类繁多，矿物嵌布特征和结构构造较为复杂，其钒铁精矿产品TFe品位较低，仅为54.08%，TiO2品位为12.55%，主要脉石矿物橄榄石和辉石。故本文针对该钒铁精矿开展了多种设备及工艺的试验研究，最终采用“细磨-深选”、“细磨-新型复合力场精选机精选”两种工艺方案为钒铁精矿合理的提质降杂工艺。在磨矿细度-400目占87.67%情况下，细磨-深选工艺可获得钒铁精矿TFe品位56.21%，回收率95.68%的指标；细磨-新型复合力场精选机精选工艺可获得钒铁精矿品位56.48%，TFe回收率97.33%，TiO2品位11.88%的指标。该技术方案对于红格地区钒铁精矿的提质降杂具有十分重要的现实意义。

| Abstract: | The vanadium-titanium magnetite in Honggenan mining area is mostly olivine-type ore, with a wide variety of mineral composition, and complex mineral intercalation characteristics and structure. Its vanadium-iron concentrate product has a low TFe grade, only 54.08%, with TiO2 The grade is 12.55%, the main gangue minerals are olivine and pyroxene. Therefore, this article has carried out experimental research on various equipment and processes for the ferro-vanadium concentrate, and finally adopted two process schemes of “fine grinding-deep selection” and “fine grinding-new type composite force field selection machine”. Reasonable quality improvement and impurity reduction process for concentrate. When the grinding fineness is -400 mesh accounting for 87.67%, the fine grinding-deep beneficiation process can obtain the TFe grade of the vanadium iron concentrate 56.21%, and the recovery rate is 95.68%; the fine grinding-new composite force field concentrator is selected The process can obtain the indexes of 56.48% ferro-vanadium concentrate grade, 97.33% TFe recovery rate, and 11.88% TiO2 grade. This technical solution has very important practical significance for the quality improvement and impurity reduction of ferro-vanadium concentrate in Hongge area. |
