钒钛磁铁矿综合利用研究现状

钒钛磁铁矿经济利用价值极高,高效绿色开发钒钛磁铁矿资源已成为当今社会发展的必然要求。从钒钛磁铁矿资源分布和综合利用现状等方面进行分析,重点探讨了高炉法、预还原电炉法、还原磨选法和钠化焙烧预还原电炉法处理钒钛磁铁矿的研究现状和工艺优缺点,指出高炉法目前在处理钒钛磁铁矿资源技术领域仍处于主导地位,但高炉法能耗高、环境污染大、资源利用率低,势必会被非高炉冶炼所取代;非高炉冶炼钒钛磁铁矿技术现在尚未完全成熟,仍存在处理量低、能耗高等劣势,需进一步改进完善。并针对以上钒钛磁铁矿利用工艺存在的弊端,提出短流程熔炼新技术,利用该技术处理钒钛磁铁矿可实现铁、钒、钛资源的高效综合利用且生产成本大幅降低。

Research Status on Comprehensive Development and Utilization of Vanadium-Titanium Magnetite

Vanadium-titanium magnetite has extremely high economic utilization value,and the efficient and green use of vanadium-titanium magnetite resources has become an inevitable requirement of today's social development. The distribu tion and comprehensive utilization status of vanadium-titanium magnetite resource was analyzed,which focuses on the re search status,advantages and disadvantages of the blast furnace method,pre-reduction-electric furnace method,reduction- grinding method,sodium calcination and pre-reduction electric furnace method to treat vanadium-titanium magnetite. Points out that the blast furnace process is has dominant position in the treatment of vanadium-titanium magnetite resource technolo gy currently. However,the blast furnace process has caused a series problems,such as high energy consumption,environ mental pollution and lower resource utilization. So it will be replaced by some non-blast furnace technology. But now the non- blast furnace technology is not fully mature,there are still disadvantages of low capacity and high energy consumption to im provement. Based on the existing beneficiation technology,the short process smelting technology is introduced as a new treat ment for the vanadium-titanium magnetite comprehensive utilization. It can realize the comprehensive utilization of vanadium- titanium magnetite,and it can greatly reduce the production costs.
