摘要
针对我国粉煤灰堆积造成的日益突出的土地和环境污染问题,论文综述了我国粉煤灰资源开发与应用现状;简要介绍了粉煤灰在大掺杂量方面的应用,如建材领域、农业领域、矿山领域和环保领域;详细介绍了粉煤灰在高附加值领域的应用现状,如粉煤灰的深度分离、氧化铝提取、稀有金属提取和高附加值产品合成等方面。最后,探讨了粉煤灰资源化利用存在的问题,并提出了未来粉煤灰资源化开发利用的发展趋势。
With the increasingly outstanding problems of land and environmental pollution caused by the accumulation of fly ash in China. This paper summarizes the present situation of development and application of fly ash resources. This paper briefly introduces the application of fly ash in large amount of doping, such as building materials, agriculture, mining and environmental protection. Moreover, the application status of fly ash in high value-added field is introduced in detail, such as deep separation of fly ash, extraction of alumina, extraction of rare metals and synthesis of high value-added products. Finally, the paper proposes the existing problems and the development trend of fly ash resource utilization in future.
