摘要: 拜耳法赤泥的强碱性使其综合利用难度增加，赤泥大量堆存极易引发重大环境安全问题，如何安全处置赤泥迄今仍是世界性难题，而赤泥脱碱是赤泥处置的关键。本文综述了拜耳法赤泥的基本性质及碱在赤泥中的存在形式和分布特征，阐述了国内外拜耳法赤泥脱碱研究进展，提出了赤泥脱碱研究的发展方向。这将为拜耳法赤泥脱碱提供技术支持，为保障氧化铝工业的持续健康发展提供科学参考。
Abstract: The high alkali of Bayer red mud makes it difficult to be used comprehensively. The majority of red mud is stored on land, but has the potential to be harmful to the surrounding environment and human health. How to dispose of red mud safely is still a worldwide difficult problem, but dealka-lization of the red mud is the key process that disposes of red mud. In this review, the basic prop-erties of Bayer red mud and the existing form and distribution features of alkali in red mud are summarized. Current status of dealkalization are illustrated in detail, the development trend of the research on dealkalization of red mud is put forward. This review provides technology support for dealkalization of Bayer red mud and a scientific reference for sustainable development of alumina industry.
