Abstract

The burgeoning accumulation of vanadium-titanium magnetite tailings (VTMT) presents a dual challenge of environmental hazard and loss of valuable metal resources. This review arrives at a crucial juncture in global efforts towards a circular economy, focusing on innovative and effective metal recovery technologies. We explore the forefront of recycling methodologies, including suspension magnetization roasting, chlorination roasting, hydrometallurgical methods, and emerging approaches like MnO₂ roasting, magnesia and calcium roasting, and microwave oxidation roasting. Our analysis juxtaposes these advanced methods against traditional techniques, emphasizing their superior environmental and resource recovery benefits. Despite promising advancements, these technologies are still in nascent stages, each presenting unique merits and limitations that necessitate further research. This paper delves into the future trajectory of VTMT recycling, emphasizing the integration of technological innovation with environmental and resource stewardship. By tackling the specific challenges of VTMT, we underscore the urgency for holistic, efficient, and eco-friendly solutions. The future of VTMT metal recovery hinges on the progressive refinement and amalgamation of these technologies, underscored by a commitment to balancing ecological concerns with societal demands.

从废物到财富：从钒钛磁铁矿尾矿中回收金属的再循环技术的最新进展

钒钛磁铁矿尾矿（VTMT）的迅速积累带来了环境危害和宝贵金属资源流失的双重挑战。本综述在全球努力实现循环经济的关键时刻发表，重点关注创新和有效的金属回收技术。我们探讨了最前沿的回收方法，包括悬浮磁化焙烧、氯化焙烧、湿法冶金方法，以及二氧化锰焙烧、镁钙焙烧和微波氧化焙烧等新兴方法。我们的分析将这些先进方法与传统技术并列，强调它们在环境和资源回收方面的优势。尽管取得了可喜的进步，但这些技术仍处于初级阶段，每种技术都有其独特的优点和局限性，需要进一步研究。本文深入探讨了 VTMT 循环利用的未来发展轨迹，强调技术创新与环境和资源管理的结合。通过应对 VTMT 所面临的具体挑战，我们强调了全面、高效和生态友好型解决方案的紧迫性。VTMT 金属回收的未来取决于这些技术的逐步完善和融合，同时还要致力于平衡生态问题和社会需求。
