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%,TiO_2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-0.038 mm 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%,TiO_2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。The vanadium-titanium magnetite in Honggenan mining area mostly belongs to the olivinetype with a wide variety of mineral composition,and complex mineral intercalation characteristics and structure.The grade of its vanadium-iron concentrate product TFe is relatively low,only 54.08%,and that of TiO2 is 12.55%.The main gangue minerals are olivine and pyroxene.Therefore,in this paper,a variety of equipments and technology tests were carried out for the vanadium and iron concentrate,and the two technology schemes of"fine grinding-deep separation"and"fine grinding-new compound field concentrator separation"were finally adopted to be the reasonable quality improving and impurity reducing technology for the vanadium and iron concentrate.When the grinding fineness is-0.038 mm accounting for 87.67%,the TFe grade and recovery rate of vanadium iron concentrate were 56.21%and 95.68%respectively by the fine grinding-deep beneficiation process c.The indexes of vanadium iron concentrate grade 56.48%,TFe recovery 97.33%and TiO2 grade 11.88%can be obtained by fine grinding-new compound field concentrator.This technical solution has very important practical significance for the quality improvement and impurity reduction of ferro-vanadium concentrate in Hongge area.
