摘要:
高铁铝土矿作为一种重要的矿产资源,因其含有较高的铁和铝含量而备受关注。本文综述了高铁铝土矿的利用现状,重点分析了其分离技术和综合利用进展。近年来,随着铝土矿资源的日益紧张,高铁铝土矿的开发利用逐渐受到重视。然而,由于高铁铝土矿中铝矿物和铁矿物嵌布均匀,分离难度大,传统的选矿方法难以有效分离铝、铁。因此,科研人员积极研发新的分离技术,如物理法、化学法及微生物法等,以提高氧化铝的品位和回收率,降低铁含量。此外,高铁铝土矿的综合利用也成为研究热点,通过提取其中的有价元素、制备高性能材料等途径,实现资源的最大化利用。本文旨在为高铁铝土矿的高效利用提供有益的参考和借鉴。High-iron bauxite, as a crucial mineral resource, has attracted considerable attention due to its high iron and aluminum content. This paper reviews the current utilization status of high-iron bauxite, with a focus on analyzing advancements in its separation technology and comprehensive years, as bauxite resources have become increasingly scarce, the development and utilization of high-iron bauxite have garnered increasing attention. However, separating aluminum and iron in high-iron bauxiis challenging due to their uniform distribution. Traditional beneficiation methods struggle to effectively separate aluminum and iron. Therefore, researchers have actively developed new separation technologies, such as physical methods, chemical methods, and microbiological methods, to improve the grade and recovery of alumina while reducing iron content. Additionally, the comprehensive utilization of high-iron bauxite has emerged as a research hotspot, aiming to maximize resource utilization through the extraction of valuable elements and the preparation of high-performance materials. This paper aims to provide a useful reference for the efficient utilization of high-iron bauxite.
