摘要:
这是一篇矿业工程领域的论文。粉煤灰不仅是燃煤电厂排放的大宗固体废弃物，同时又是一种潜在的二次资源。目前，粉煤灰的资源化利用虽然涉及领域比较广泛，但高值化利用率偏低。粉煤灰的主要化学成分为二氧化硅和氧化铝，充分利用其中的铝硅资源是提高其资源化利用率的重要途径之一。本文针对粉煤灰在提取冶金级氧化铝、制备非冶金级氧化铝、白炭黑、二氧化硅气凝胶以及硅铝复合材料等高附加值产品的应用情况进行了综述，对高值化利用目前存在的问题进行了分析，并指出了未来发展趋势。
Abstract:This is an article in the field of mining engineering. Fly ash is not only a large amount of solid waste discharged from coal-fired power plants, but also a potential secondary resource. At present, although the resource utilization of fly ash covers a wide range of fields, the high value utilization rate is low. The main chemical components of fly ash are silicon and alumina. Making full use of aluminum and silicon resources is one of the important ways to improve its resource utilization. In this article, the application of fly ash in the extraction of metallurgical grade alumina, preparation of non-metallurgical grade alumina, silica, silica aerogels, silicon-aluminum composites and other high value-added products are reviewed. The existing problems of high value utilization are analyzed and the future development trend is pointed out.
