摘要： 攀西地区钒钛磁铁矿是我国重要的特色资源，但由于其TiO2含量高，矿物相复杂，属于难冶炼矿石。早在1958年6月叶渚沛先生发表了《攀枝花含钛铁矿的紧急问题》的书面意见，其中“紧急问题”是突破某些国外学者的“用高炉冶炼这种矿石成功的希望甚微”的框框，依靠国内的科研力量攻克攀西地区钒钛磁铁矿高炉冶炼的难题。在全国各相关行业的大力协作攻关下，我国已成功突破了攀西地区钒钛磁铁矿高炉冶炼的难题，并进一步提升了强化冶炼的水平，整体达到世界领先水平。近年来除冶炼水平不断提升外，在资源综合利用水平提升方面也进行了大量具有原创意义的研究工作。重庆大学是国内最早开展钒钛磁铁矿冶炼和综合利用研究的单位之一，多年来始终把钒钛磁铁矿冶金及资源高效利用作为冶金学科首要的研究方向，对高炉冶炼钒钛磁铁矿的独特工艺进行了较系统的理论与工艺研究，形成了鲜明的研究特色。近年来围绕高炉高配比钒钛磁铁矿冶炼技术、含钛高炉渣提钛和大型电炉钛渣冶炼技术以及钒资源高效清洁提取技术等方面与企业紧密合作，在理论和实验研究方法上进行突破，取得了良好的进展。本综述就近年来重庆大学在攀西钒钛磁铁矿高效冶金及清洁提取方面所做的工作，进行简要介绍，以纪念叶渚沛、林衍先等老一辈科学工作者为攀西钒钛磁铁矿开发利用做出的科研贡献，并秉承他们脚踏实地、勇于创新的科学精神，推动“双碳”目标下的攀西地区钒钛磁铁矿绿色智能冶金和资源高效利用的发展。

Abstract: The vanadium-titanium magnetite ore is an important characteristic resource in Panxi area of China, but it is difficult to smelt because of its high TiO2 content and complex mineral phase. As early as June 1958, Mr. Chu-Phay Yap issued a written opinion on "urgent problems of iron ore bearing titanium in Panzhihua". Among them, the "urgent problem" is to break through some foreign scholars' judgment: "smelting this ore with blast furnace has little hope of success", and rely on domestic scientific research to overcome the problems of smelting vanadium-titanium magnetite ore with blast furnace in Panxi area. With the cooperation of related industries and research forces in China, it has been successfully broken through that difficult problem of smelting of vanadium-titanium magnetite ore with blast furnace in Panxi region, and further improved the level of smelting, reaching the world higher level in whole. In recent years, in addition to the continuous improvement of smelting level, the level of comprehensive utilization of that kind ore has also carried out a lot of original research work. Chongqing University is one of the earliest research institutes on comprehensive utilization of vanadium-titanium magnetite ore smelting. Over the years it has always took the vanadium-titanium magnetite smelting and its efficient utilization as the primary of metallurgical science research topic in the Chongqing University, and the unique processes of blast furnace smelting vanadium-titanium magnetite ore are studied systematically in the theory and technology, that has formed distinctive research features. In recent years, it has also been made that breakthroughs in theoretical and experimental research methods and made good progress in close cooperation with enterprises on smelting technology of high ratio vanadium-titanium magnetite ore in blast furnace, titanium extraction from titanium-containing blast furnace slag and titanium slag smelting technology in large electric furnace, as well as efficient and clean extraction technology of vanadium resources. This review gives a brief introduction on the clean metallurgy and efficient extraction research progress on Panxi vanadium-titanium magnetite ore in Chongqing University, to commemorate the contribution of Chu-Phay Yap and Yanxian Lin et al. scientific workers for the development and utilization of Panxi vanadium-titanium magnetite ore, and uphold their feet on the ground, as well as the innovation of scientific spirit. To promote the development of green and intelligent metallurgy and resource efficient utilization of vanadium-titanium magnetite ore in Panxi region under the carbon peaking and carbon neutrality goals.
