摘要/Abstract

摘要： 介绍了钒钛磁铁矿的资源概况、钒钛磁铁矿精矿综合利用现状及钒钛磁铁精矿中钛铁分离的意义，主要从高炉法、非高炉工艺、选矿工艺和其它钛铁分离技术等几个方面综述了目前国内外钒钛磁铁精矿中钛铁分离的研究进展。非高炉工艺中采用直接还原—磨选法，铁和钛的金属转化率高、能耗小，铁精矿和钛精矿品位相对较高，该工艺发展前景广阔。采用化学—物理联合选矿新工艺处理钒钛磁铁精矿，解决了物理选矿流程不能从根本上解决钛铁紧密共生的问题，该新工艺流程短、成本低且钛铁回收率和品位较高，对实现钒钛磁铁精矿中钛铁分离具有明显优势。因此，针对钒钛磁铁精矿中钛铁分离研究现状，研究新型、高效、环保、廉价的还原剂和环保、低成本、来源广泛的添加剂是今后非高炉工艺处理钒钛磁铁精矿的研究热点。另外，开发流程短、成本低、操作简单的选矿新工艺是未来实现钒钛磁铁精矿中钛铁分离的重要研究方向。

Abstract: Introduce the general situation of vanadium-titanium magnetite resources， the comprehensive utilization status of vanadium-titanium magnetite concentrate and the significance of separation of iron and titanium in vanadium-titanium magnetite concentrate. Mainly reviews the current research advances in titanium and iron separation of vanadium-titanium magnetite concentrate from several aspects: blast furnace process， non-blast furnace process， mineral process and other titanium and iron separation technologies. Compared with the non-blast furnace process， the direct reduction-grinding method has high metal conversion rate and low energy consumption of iron and titanium， and the iron concentrate and titanium concentrate have relatively high grade. The process has broad development prospects. The chemical-physical combined mineral process is used to treat the vanadium-titanium magnet concentrate， which solves the problem that the physical mineral process cannot fundamentally solve the problem of close symbiotic symmetry of titanium and iron. The new process is short， the cost is low， and the recovery rate and grade of iron and titanium are high. It has obvious advantages in realizing the separation of titanium and iron in vanadium-titanium magnetite concentrate. Therefore， in view of the research status of titanium-iron separation in vanadium-titanium magnetite concentrate， research on new， high-efficiency， environmentally friendly， inexpensive reducing agents and environmentally friendly， low-cost， wide-ranging additives are the research focus for non-blast furnace processing of vanadium-titanium magnetite concentrates in the future. In addition， the development of a new mineral processing technology with short process， low cost and simple operation is the main development direction for the separation of titanium and iron in vanadium titanium magnetite concentrate in the future.
