摘　　要：高铝粉煤灰含有大量氧化铝,在40%左右,接近于中等品位铝矾土中氧化铝含量。我国的铝土矿大量依靠进口,将高铝粉煤灰作为铝的一种重要生产资源加以利用,对我国铝工业的可持续发展具有非常重要的战略意义。粉煤灰在高技术领域越来越多地被使用和研究,提取粉煤灰中的有用元素研制工程塑料玻璃钢等填料,或用于制备处理污水所用的复合型高分子混凝剂等将为粉煤灰的综合利用开拓新的途径。High-aluminum fly ash contains a large amount of alumina,which is about 40%and close to the alumina content in medium-grade bauxite.China’s bauxite relies heavily on imports and uses high-aluminum fly ash as an important production resource for aluminum,which has very important strategic significance for the sustainable development of China’s aluminum industry.Fly ash is increasingly used and researched in the high-tech field.Extracting useful elements in fly ash to develop fillers such as engineering plastic glass fiber reinforced plastics,or composite polymer coagulants used to prepare sewage treatment will Comprehensive utilization of fly ash opens up new ways.
