摘要: 赤泥是在提取氧化铝过程中产生的强碱性废渣。在分析了赤泥的大量堆存不仅占用土地,污染土壤、水、空气,腐蚀钢构,及造成有用成分浪费等危害的基础上,对赤泥的综合利用研究与实践情况进行了重点介绍,从现阶段看,赤泥的综合利用方向主要有生产新型建材与陶瓷,制造净化水和空气的吸附材料,制备新型功能材料及回收其中的有价金属,并对赤泥的综合利用前景进行了展望。

Abstract: Red mud is a strong alkaline waste generated during the extraction of alumina. Based on the analysis of the hazards of red mud storage, such as occupying land, polluting soil, water and air, corroding steel structure and wasting useful components, the comprehensive utilization research and practice situations of red mud are emphatically introduced. At this stage, comprehensive utilizations of red mud were summarized as follows: construction materials and ceramics, absorbing adsorbent materials for purifying water and air,functional materials and recovery of valuable metals. The prospect of comprehensive utilization of red mud is also prospected.
