Abstract

The author investigated the modes of thermal and heat-and-radiation treatment of ferruginous bauxite from Vezhayu–Vorykva deposit and revealed different mechanisms of mineral transformations. Under thermal treatment, oxo-hydroxides transform into anhydrous iron and aluminum oxides, while under heat-and-radiation treatment, scattered microelements form metal alloys and new minerals. It is recommended to ground ferruginous bauxite processing on basic science, first of all, nanomineralogy, and on phenomenon of phase heterogenization. This approach can promote an increase in recovery of fine particles of aluminum and other valuable components from low-grade bauxite and red mud by eco-friendly techniques.

加工铁含量和有价成分细颗粒增加的铝土矿的工艺流程图和建议

摘要作者研究了 Vezhayu-Vorykva 矿床铁铝土矿的热处理和热辐射处理模式，揭示了矿物转化的不同机制。在热处理过程中，氧化氢氧化物转变为无水铁和铝氧化物，而在热辐射处理过程中，分散的微量元素形成金属合金和新矿物。建议将铁铝土矿加工建立在基础科学之上，首先是纳米矿物学和相异质化现象。这种方法可以促进通过生态友好技术从低品位铝土矿和赤泥中回收更多的细颗粒铝和其他有价值成分。
